HARVEY, SIR GEORGE (1806-1876), Scottish painter, the son of a watchmaker, was born at St Ninians, near Stirling, in February 1806. Soon after his birth his parents removed to Stirling, where George was apprenticed to a bookseller. His love for art having, however, become very decided, in his eighteenth year he entered the Trustees’ Academy at Edinburgh. Here he so distinguished himself that in 1826 he was invited by the Scottish artists, who had resolved to found a Scottish academy, to join it as an associate. Harvey’s first picture, “A Village School,” was exhibited in 1826 at the Edinburgh Institution; and from the time of the opening of the Academy in the following year he continued annually to exhibit. His best-known pictures are those depicting historical episodes in religious history from a puritan or evangelical point of view, such as “Covenanters Preaching,” “Covenanters’ Communion,” “John Bunyan and his Blind Daughter,” “Sabbath Evening,” and the “Quitting of the Manse.” He was, however, equally popular in Scotland for subjects not directly religious; and “The Bowlers,” “A Highland Funeral,” “The Curlers,” “A Schule Skailin’,” and “Children Blowing Bubbles in the Churchyard of Greyfriars’, Edinburgh,” manifest the same close observation of character, artistic conception and conscientious elaboration of details. In “The Night Mail” and “Dawn Revealing the New World to Columbus” the aspects of nature are made use of in different ways, but with equal happiness, to lend impressiveness and solemnity to human concerns. He also painted landscapes and portraits. In 1829 he was elected a fellow of the Royal Scottish Academy; in 1864 he succeeded Sir J. W. Gordon as president; and he was knighted in 1867. He died at Edinburgh on the 22nd of January 1876.

Sir George Harvey was the author of a paper on the “Colour of the Atmosphere,” read before the Edinburgh Royal Society, and afterwards published with illustrations in Good Words; and in 1870 he published a small volume entitled Notes of the Early History of the Royal Scottish Academy. Selections from the Works of Sir George Harvey, P.R.S.A., described by the Rev. A. L. Simpson, F.S.A. Scot., and photographed by Thomas Annan, appeared at Edinburgh in 1869.

HARVEY, WILLIAM (1578-1657), English physician, the discoverer of the circulation of the blood, was the eldest son of Thomas Harvey, a prosperous Kentish yeoman, and was born at Folkestone on the 1st of April 1578. After passing through the grammar school of Canterbury, on the 31st of May 1593, having just entered his sixteenth year, he became a pensioner of Caius College, Cambridge, at nineteen he took his B.A. degree, and soon after, having chosen the profession of medicine, he went to study at Padua under H. Fabricius and Julius Casserius. At the age of twenty-four Harvey became doctor of medicine, in April 1602. Returning to England in the first year of James I., he settled in London; and two years later he married the daughter of Dr Lancelot Browne, who had been physician to Queen Elizabeth. In the same year he became a candidate of the Royal College of Physicians, and was duly admitted a fellow (June 1607). In 1609 he obtained the reversion of the post of physician to St Bartholomew’s hospital. His application was supported by the king himself and by Dr Henry Atkins (1558-1635), the president of the college, and on the death of Dr Wilkinson in the course of the same year he succeeded to the post. He was thrice censor of the college, and in 1615 was appointed Lumleian lecturer.

In 1616 he began his course of lectures, and first brought forward his views upon the movements of the heart and blood. Meantime his practice increased, and he had the lord chancellor, Francis Bacon, and the earl of Arundel among his patients. In 1618 he was appointed physician extraordinary to James I., and on the next vacancy physician in ordinary to his successor. In 1628, the year of the publication of the Exercitatio anatomica de motu cordis et sanguinis, he was elected treasurer of the College of Physicians, but at the end of the following year he resigned the office, in order, by command of Charles I., to accompany the young duke of Lennox (James Stuart, afterwards duke of Richmond) on his travels. He appears to have visited Italy, and returned in 1632. Four years later he accompanied the earl of Arundel on his embassy to the emperor Ferdinand II. He was eager in collecting objects of natural history, sometimes causing the earl anxiety for his safety by his excursions in a country infested by robbers in consequence of the Thirty Years’ War. In a letter written on this journey, he says: “By the way we could scarce see a dogg, crow, kite, raven, or any bird, or anything to anatomise; only sum few miserable people, the reliques of the war and the plague, whom famine had made anatomies before I came.” Having returned to his practice in London at the close of the year 1636, he accompanied Charles I. in one of his journeys to Scotland (1639 or 1641). While at Edinburgh he visited the Bass Rock; he minutely describes its abundant population of sea-fowl in his treatise De generatione, and incidentally speaks of the account then credited of the solan goose growing on trees as a fable. He was in attendance on the king at the battle of Edgehill (October 1642), where he withdrew under a hedge with the prince of Wales and the duke of York (then boys of twelve and ten years old), “and took out of his pocket a book and read. But he had not read very long before a bullet of a great gun grazed on the ground near him, which made him remove his station,” as he afterwards told John Aubrey. After the indecisive battle, Harvey followed Charles I. to Oxford, “where,” writes the same gossiping narrator, “I first saw him, but was then too young to be acquainted with so great a doctor. I remember he came several times to our college (Trinity) to George Bathurst, B.D. who had a hen to hatch eggs in his chamber, which they opened daily to see the progress and way of generation.” In Oxford he remained three years, and there was some chance of his being superseded in his office at St Bartholomew’s hospital, “because he hath withdrawn himself from his charge, and is retired to the party in arms against the Parliament.” It was no doubt at this time that his lodgings at Whitehall were searched, and not only the furniture seized but also invaluable manuscripts and anatomical preparations.1

While with the king at Oxford he was made warden of Merton College, but a year later, in 1646, that city surrendered to Fairfax, and Harvey returned to London. He was now sixty-eight years old, and, having resigned his appointments and relinquished the cares of practice, lived in learned retirement with one or other of his brothers. It was in his brother Daniel’s house at Combe that Dr (afterwards Sir George) Ent, a faithful friend and disciple (1604-1689), visited him in 1650. “I found him,” he says, “with a cheerful and sprightly countenance investigating, like Democritus, the nature of things. Asking if all were well with him—‘How can that be,’ he replied, ‘when the state is so agitated with storms and I myself am yet in the open sea? And indeed, were not my mind solaced by my studies and the recollection of the observations I have formerly made, there is nothing which should make me desirous of a longer continuance. But thus employed, this obscure life and vacation from public cares which would disgust other minds is the medicine of mine.’” The work on which he had been chiefly engaged at Oxford, and indeed since the publication of his treatise on the circulation in 1628, was an investigation into the recondite but deeply interesting subject of generation. Charles I. had been an enlightened patron of Harvey’s studies, had put the royal deer parks at Windsor and Hampton Court at his disposal, and had watched his demonstration of the growth of the chick with no less interest than the movements of the living heart. Harvey had now collected a large number of observations, though he would probably have delayed their publication. But Ent succeeded in obtaining the manuscripts, with authority to print them or not as he should find them. “I went from him,” he says, “like another Jason in possession of the golden fleece, and when I came home and perused the pieces singly, I was amazed that so vast a treasure should have been so long hidden.” The result was the publication of the Exercitationes de generatione (1651).

This was the last of Harvey’s labours. He had now reached his seventy-third year. His theory of the circulation had been opposed and defended, and was now generally accepted by the most eminent anatomists both in his own country and abroad. He was known and honoured throughout Europe, and his own college (Caius) voted a statue in his honour (1652) viro monumentis suis immortali. In 1654 he was elected to the highest post in his profession, that of president of the college; but the following day he met the assembled fellows, and, declining the honour for himself on account of the infirmities of age, recommended the re-election of the late president Dr Francis Prujean (1593-1666). He accepted, however, the office of consiliarius, which he again held in the two following years. He had already enriched the college with other gifts besides the honour of his name. He had raised for them “a noble building of Roman architecture (rustic work with Corinthian pilasters), comprising a great parlour or conversation room below and a library above”; he had furnished the library with books, and filled the museum with “simples and rarities,” as well as with specimens of instruments used in the surgical and obstetric branches of medicine. At last he determined to give to his beloved college his paternal estate at Burmarsh in Kent. His wife had died some years before, his brothers were wealthy men, and he was childless, so that he was defrauding no heir when, in July 1656, he made the transfer of this property, then valued at £56 per annum, with provision for a salary to the college librarian and for the endowment of an annual oration, which is still given on the anniversary of the day. The orator, so Harvey orders in his deed of gift, is to exhort the fellows of the college “to search out and study the secrets of nature by way of experiment, and also for the honour of the profession to continue mutual love and affection among themselves.”

Harvey, like his contemporary and great successor Thomas Sydenham, was long afflicted with gout, but he preserved his activity of mind to an advanced age. In his eightieth year, on the 3rd of June 1657, he was attacked by paralysis, and though deprived of speech was able to send for his nephews and distribute his watch, ring, and other personal trinkets among them. He died the same evening, “the palsy giving him an easy passport,” and was buried with great honour in his brother Eliab’s vault at Hempstead in Essex, annorum et famae satur. In 1883 the lead coffin containing his remains was enclosed in a marble sarcophagus and moved to the Harvey chapel within the church.

John Aubrey, to whom we owe most of the minor particulars about Harvey which have been preserved, says: “In person he was not tall, but of the lowest stature, round faced, olivaster complexion, little eyes, round, very black, full of spirits; his hair black as a raven, but quite white twenty years before he died.” The best portrait of him extant is by Cornelius Jansen in the library of the College of Physicians, one of those rescued from the great fire, which destroyed their original hall in 1666. It has been often engraved, and is prefixed to the fine edition of his works published in 1766.

Harvey’s Work on the Circulation.—In estimating the character and value of the discovery announced in the Exercitatio de motu cordis et sanguinis, it is necessary to bear in mind the previous state of knowledge on the subject. Aristotle taught that in man and the higher animals the blood was elaborated from the food in the liver, thence carried to the heart, and sent by it through the veins over the body. His successors of the Alexandrian school of medicine, Erasistratus and Herophilus, further elaborated his system, and taught that, while the veins carried blood from the heart to the members, the arteries carried a subtle kind of air or spirit. For the practical physician only two changes had been made in this theory of the circulation between the Christian era and the 16th century. Galen had discovered that the arteries were not, as their name implies, merely air-pipes, but that they contained blood as well as vital air or spirit. And it had been gradually ascertained that the nerves (νεῦρα) which arose from the brain and conveyed “animal spirits” to the body were different from the tendons or sinews (νεῦρα) which attach muscles to bones. First, then, the physicians of the time of Thomas Linacre knew that the blood is not stagnant in the body. So did Shakespeare and Homer, and every augur who inspected the entrails of a victim, and every village barber who breathed a vein. Plato even uses the expression to τὸ αἷμα κατὰ πάντα τὰ μέλη σφοδρῶς περιφέρεσθαι. But no one had a conception of a continuous stream returning to its source (a circulation in the true sense of the word) either in the system or in the lungs. If they used the word circulatio, as did Caesalpinus,2 it was as vaguely as the French policeman cries “Circulez.” The movements of the blood were in fact thought to be slow and irregular in direction as well as in speed, like the “circulation” of air in a house, or the circulation of a crowd in the streets of a city. Secondly, they supposed that one kind of blood flowed from the liver to the right ventricle of the heart, and thence to the lungs and the general system by the veins, and that another kind flowed from the left ventricle to the lungs and general system by the arteries. Thirdly, they supposed that the septum of the heart was pervious and allowed blood to pass directly from the right to the left side. Fourthly, they had no conception of the functions of the heart as the motor power of the movement of the blood. They doubted whether its substance was muscular; they supposed its pulsation to be due to expansion of the spirits it contained; they believed the only dynamic effect which it had on the blood to be sucking it in during its active diastole, and they supposed the chief use of its constant movements to be the due mixture of blood and spirits.

Of the great anatomists of the 16th century, Sylvius (In Hipp. et Gal. phys. partem anatom. isagoge) described the valves of the veins; Vesalius (De humani corporis fabrica, 1542) ascertained that the septum between the right and left ventricles is complete, though he could not bring himself to deny the invisible pores which Galen’s system demanded. Servetus, in his Christianismi restitutio (1553), goes somewhat farther than his fellow-student Vesalius, and says: “Paries ille medius non est aptus ad communicationem et elaborationem illam; licet aliquid resudare possit”; and, from this anatomical fact and the large size of the pulmonary arteries he concludes that there is a communication in the lungs by which blood passes from the pulmonary artery to the pulmonary vein: “Eodem artificio quo in hepate fit transfusio a vena porta ad venam cavam propter sanguinem, fit etiam in pulmone transfusio a vena arteriosa ad arteriam venosam propter spiritum.” The natural spirit of the left side and the vital spirit of the right side of the heart were therefore, he concluded, practically the same, and hence two instead of three distinct spiritus should be admitted. It seems doubtful whether even Servetus rightly conceived of the entire mass of the blood passing through the pulmonary artery and the lungs. The transference of the spiritus naturalis to the lungs, and its return to the left ventricle as spiritus vitalis, was the function which he regarded as important. Indeed a true conception of the lesser circulation as a transference of the whole blood of the right side to the left was impossible until the corresponding transference in the greater or systematic circulation was discovered. Servetus, however, was the true predecessor of Harvey in physiology, and his claims to that honour are perfectly authentic and universally admitted.3

The way then to Harvey’s great work had been paved by the discovery of the valves in the veins, and by that of the lesser circulation—the former due to Sylvius and Fabricius, the latter to Servetus—but the significance of the valves was unsuspected and the fact of even the pulmonary circulation was not generally admitted in its full meaning.

In his treatise Harvey proves (1) that it is the contraction, not the dilatation, of the heart which coincides with the pulse, and that the ventricles as true muscular sacs squeeze the blood which they contain into the aorta and pulmonary artery; (2) that the pulse is not produced by the arteries enlarging and so filling, but by the arteries being filled with blood and so enlarging; (3) that there are no pores in the septum of the heart, so that the whole blood in the right ventricle is sent to the lungs and round by the pulmonary veins to the left ventricle, and also that the whole blood in the left ventricle is again sent into the arteries, round by the smaller veins into the venae cavae, and by them to the right ventricle again—thus making a complete “circulation”; (4) that the blood in the arteries and that in the veins is the same blood; (5) that the action of the right and left sides of the heart, auricles, ventricles and valves, is the same, the mechanism in both being for reception and propulsion of liquid and not of air, since the blood on the right side, though mixed with air, is still blood; (6) that the blood sent through the arteries to the tissues is not all used, but that most of it runs through into the veins; (7) that there is no to and fro undulation in the veins, but a constant stream from the distant parts towards the heart; (8) that the dynamical starting-point of the blood is the heart and not the liver.

The method by which Harvey arrived at his complete and almost faultless solution of the most fundamental and difficult problem in physiology has been often discussed, and is well worthy of attention. He begins his treatise by pointing out the many inconsistencies and defects in the Galenical theory, quoting the writings of Galen himself, of Fabricius, Columbus and others, with great respect, but with unflinching criticism. For, in his own noble language, wise men must learn anatomy, not from the decrees of philosophers, but from the fabric of nature herself, “nec ita in verba jurare antiquitatis magistrae, ut veritatem amicam in apertis relinquant, et in conspectu omnium deserant.” He had, as we know, not only furnished himself with all the knowledge that books and the instructions of the best anatomists of Italy could give, but, by a long series of dissections, had gained a far more complete knowledge of the comparative anatomy of the heart and vessels than any contemporary—we may almost say than any successor—until the times of John Hunter and J. F. Meckel. Thus equipped, he tells us that he began his investigations into the movements of the heart and blood by looking at them—i.e. by seeing their action in living animals. After a modest preface, he heads his first chapter “Ex vivorum dissectione, qualis sit cordis motus.” He minutely describes what he saw and handled in dogs, pigs, serpents, frogs and fishes, and even in slugs, oysters, lobsters and insects, in the transparent minima squilla, “quae Anglice dicitur a shrimp,” and lastly in the chick while still in the shell. In these investigations he used a perspicillum or simple lens. He particularly describes his observations and experiments on the ventricles, the auricles, the arteries and the veins. He shows how the arrangement of the vessels in the foetus supports his theory. He adduces facts observed in disease as well as in health to prove the rapidity of the circulation. He explains how the mechanism of the valves in the veins is adapted, not, as Fabricius believed, to moderate the flow of blood from the heart, but to favour its flow to the heart. He estimates the capacity of each ventricle, and reckons the rate at which the whole mass of blood passes through it. He elaborately and clearly demonstrates the effect of obstruction of the blood-stream in arteries or in veins, by the forceps in the case of a snake, by a ligature on the arm of a man, and illustrates his argument by figures. He then sums up his conclusion thus: “Circulari quodam motu, in circuitu, agitari in animalibus sanguinem, et esse in perpetuo motu; et hanc esse actionem sive functionem cordis quam pulsu peragit; et omnino motus et pulsus cordis causam unam esse.” Lastly, in the 15th, 16th and 17th chapters, he adds certain confirmatory evidence, as the effect of position on the circulation, the absorption of animal poisons and of medicines applied externally, the muscular structure of the heart and the necessary working of its valves. The whole treatise, which occupies only 67 pages of large print in the quarto edition of 1766, is a model of accurate observation, patient accumulation of facts, ingenious experimentation, bold yet cautious hypothesis and logical deduction.

In one point only was the demonstration of the circulation incomplete. Harvey could not discover the capillary channels by which the blood passes from the arteries to the veins. This gap in the circulation was supplied several years later by the great anatomist Marcello Malpighi, who in 1661 saw in the lungs of a frog, by the newly invented microscope, how the blood passes from the one set of vessels to the other. Harvey saw all that could be seen by the unaided eye in his observations on living animals; Malpighi, four years after Harvey’s death, by another observation on a living animal, completed the splendid chain of evidence. If this detracts from Harvey’s merit it leaves Servetus no merit at all. But in fact the existence of the channels first seen by Malpighi was as clearly pointed to by Harvey’s reasoning as the existence of Neptune by the calculations of Leverrier and of Adams.

Harvey himself and all his contemporaries were well aware of the novelty and importance of his theory. He says in the admirable letter to Dr Argent, president of the College of Physicians, which follows the dedication of his treatise to Charles I., that he should not have ventured to publish “a book which alone asserts that the blood pursues its course and flows back again by a new path, contrary to the received doctrine taught so many ages by innumerable learned and illustrious men,” if he had not set forth his theory for more than nine years in his college lectures, gradually brought it to perfection, and convinced his colleagues by actual demonstrations of the truth of what he advanced. He anticipates opposition, and even obloquy or loss, from the novelty of his views. These anticipations, however, the event proved to have been groundless. If we are to credit Aubrey indeed, he found that after the publication of the De motu “he fell mightily in his practice; ’twas believed by the vulgar that he was crackbrained, and all the physicians were against him.” But the last assertion is demonstrably untrue; and if apothecaries and patients ever forsook him, they must soon have returned, for Harvey left a handsome fortune. By his own profession the book was received as it deserved. So novel a doctrine was not to be accepted without due inquiry, but his colleagues had heard his lectures and seen his demonstrations for years; they were already convinced of the truth of his theory, urged its publication, continued him in his lectureship, and paid him every honour in their power. In other countries the book was widely read and much canvassed. Few accepted the new theory; but no one dreamt of claiming the honour of it for himself, nor for several years did any one pretend that it could be found in the works of previous authors. The first attack on it was a feeble tract by one James Primerose, a pupil of Jean Riolan (Exerc. et animadv. in libr. Harvei de motu cord. et sang., 1630). Five years later Parisanus, an Italian physician, published his Lapis Lydius de motu cord. et sang. (Venice, 1635), a still more bulky and futile performance. Primerose’s attacks were “imbellia pleraque” and “sine ictu”; that of Parisanus “in quamplurimis turpius,” according to the contemporary judgment of Johann Vessling. Their dulness has protected them from further censure. Caspar Hoffmann, professor at Nuremberg, while admitting the truth of the lesser circulation in the full Harveian sense, denied the rest of the new doctrine. To him the English anatomist replied in a short letter, still extant, with great consideration yet with modest dignity, beseeching him to convince himself by actual inspection of the truth of the facts in question. He concludes: “I accept your censure in the candid and friendly spirit in which you say you wrote it; do you also the same to me, now that I have answered you in the same spirit.” This letter is dated May 1636, and in that year Harvey passed through Nuremberg with the earl of Arundel, and visited Hoffmann. But he failed to convince him; “nec tamen valuit Harveius vel coram,” writes P. M. Schlegel, who, however, afterwards succeeded in persuading the obstinate old Galenist to soften his opposition to the new doctrine, and thinks that his complete conversion might have been effected if he had but lived a little longer—“nec dubito quin concessisset tandem in nostra castra.” While in Italy the following year Harvey visited his old university of Padua, and demonstrated his views to Professor Vessling. A few months later this excellent anatomist wrote him a courteous and sensible letter, with certain objections to the new theory. The answer to this has not been preserved, but it convinced his candid opponent, who admitted the truth of the circulation in a second letter (both were published in 1640), and afterwards told a friend, “Harveium nostrum si audis, agnosces coelestem sanguinis et spiritus ingressum ex arteriis per venas in dextrum cordis sinum.” Meanwhile a greater convert, R. Descartes, in his Discours sur la méthode (1637) had announced his adhesion to the new doctrine, and refers to “the English physician to whom belongs the honour of having first shown that the course of the blood in the body is nothing less than a kind of perpetual movement in a circle.” J. Walaeus of Leyden, H. Regius of Utrecht and Schlegel of Hamburg successively adopted the new physiology. Of these professors, Regius was mauled by the pertinacious Primerose and mauled him in return (Spongia qua eluuntur sordes quae Jac. Primirosius, &c., and Antidotum adv. Spongiam venenatam Henr. Regii). Descartes afterwards repeated Harvey’s vivisections, and, more convinced than ever, demolished Professor V. F. Plempius of Louvain, who had written on the other side. George Ent also published an Apologia pro circulatione sanguinis in answer to Parisanus.

At last Jean Riolan ventured to publish his Enchiridium anatomicum (1648), in which he attacks Harvey’s theory, and proposes one of his own. Riolan had accompanied the queen dowager of France (Maria de’ Medici) on a visit to her daughter at Whitehall, and had there met Harvey and discussed his theory. He was, in the opinion of the judicious Haller, “vir asper et in nuperos suosque coaevos immitis ac nemini parcens, nimis avidus suarum laudum praeco, et se ipso fatente anatomicorum princeps.” Harvey replied to the Enchiridium with perfectly courteous language and perfectly conclusive arguments, in two letters De circulatione sanguinis, which were published at Cambridge in 1649, and are still well worth reading. He speaks here of the “circuitus sanguinis a me inventus.” Riolan was unconvinced, but lived to see another professor of anatomy appointed in his own university who taught Harvey’s doctrines. Even in Italy, Trullius, professor of anatomy at Rome, expounded the new doctrine in 1651. But the most illustrious converts were Jean Pecquet of Dieppe, the discoverer of the thoracic duct, and of the true course of the lacteal vessels, and Thomas Bartholinus of Copenhagen, in his Anatome ex omnium veterum recentiorumque observationibus, imprimis institutionibus beati mei parentis Caspari Bartholini, ad circulationem Harveianam et vasa lymphatica renovata (Leiden, 1651). At last Plempius also retracted all his objections; for, as he candidly stated, “having opened the bodies of a few living dogs, I find that all Harvey’s statements are perfectly true.” Hobbes of Malmesbury could thus say in the preface to his Elementa philosophiae that his friend Harvey, “solus quod sciam, doctrinam novam superata invidia vivens stabilivit.”

It has been made a reproach to Harvey that he failed to appreciate the importance of the discoveries of the lacteal and lymphatic vessels by G. Aselli, J. Pecquet and C. Bartholinus. In three letters on the subject, one to Dr R. Morison of Paris (1652) and two to Dr Horst of Darmstadt (1655), a correspondent of Bartholin’s, he discusses these observations, and shows himself unconvinced of their accuracy. He writes, however, with great moderation and reasonableness, and excuses himself from investigating the subject further on the score of the infirmities of age; he was then above seventy-four. The following quotation shows the spirit of these letters: “Laudo equidem summopere Pecqueti aliorumque in indaganda veritate industriam singularem, nec dubito quin multa adhuc in Democriti puteo abscondita sint, a venturi saeculi indefatigabili diligentia expromenda.” Bartholin, though reasonably disappointed in not having Harvey’s concurrence, speaks of him with the utmost respect, and generously says that the glory of discovering the movements of the heart and of the blood was enough for one man.

Harvey’s Work on Generation.—We have seen how Dr. Ent persuaded his friend to publish this book in 1651. It is between five and six times as long as the Exerc. de motu cord. et sang., and is followed by excursus De partu, De uteri membranis, De conceptione; but, though the fruit of as patient and extensive observations, its value is far inferior. The subject was far more abstruse, and in fact inaccessible to proper investigation without the aid of the microscope. And the field was almost untrodden since the days of Aristotle. Fabricius, Harvey’s master, in his work De formatione ovi et pulli (1621), had alone preceded him in modern times. Moreover, the seventy-two chapters which form the book lack the co-ordination so conspicuous in the earlier treatise, and some of them seem almost like detached chapters of a system which was never completed or finally revised.

Aristotle had believed that the male parent furnished the body of the future embryo, while the female only nourished and formed the seed; this is in fact the theory on which, in the Eumenides of Aeschylus, Apollo obtains the acquittal of Orestes. Galen taught almost as erroneously that each parent contributes seeds, the union of which produced the young animal. Harvey, after speaking with due honour of Aristotle and Fabricius, begins rightly “ab ovo”; for, as he remarks, “eggs cost little and are always and everywhere to be had,” and moreover “almost all animals, even those which bring forth their young alive, and man himself, are produced from eggs” (“omnia omnino animalia, etiam vivipara, atque hominem adeo ipsum, ex ovo progigni”). This dictum, usually quoted as “omne vivurn ex ovo,” would alone stamp this work as worthy of the discoverer of the circulation of the blood, but it was a prevision of genius, and was not proved to be a fact until K. E. von Baer discovered the mammalian ovum in 1827. Harvey proceeds with a careful anatomical description of the ovary and oviduct of the hen, describes the new-laid egg, and then gives an account of the appearance seen on the successive days of incubation, from the 1st to the 6th, the 10th and the 14th, and lastly describes the process of hatching. He then comments upon and corrects the opinions of Aristotle and Fabricius, declares against spontaneous generation (though in one passage he seems to admit the current doctrine of production of worms by putrefaction as an exception), proves that there is no semen foemineum, that the chalazae of the hen’s eggs are not the semen galli, and that both parents contribute to the formation of the egg. He describes accurately the first appearance of the ovarian ova as mere specks, their assumption of yelk and afterwards of albumen. In chapter xlv. he describes two methods of production of the embryo from the ovum: one is metamorphosis, or the direct transformation of pre-existing material, as a worm from an egg, or a butterfly from an aurelia (chrysalis); the other is epigenesis, or development with addition of parts, the true generation observed in all higher animals. Chapters xlvi.-l. are devoted to the abstruse question of the efficient cause of generation, which, after much discussion of the opinions of Aristotle and of Sennertius, Harvey refers to the action of both parents as the efficient instruments of the first great cause.4 He then goes on to describe the order in which the several parts appear in the chick. He states that the punctum saliens or foetal heart is the first organ to be seen, and explains that the nutrition of the chick is not only effected by yelk conveyed directly into the midgut, as Aristotle taught, but also by absorption from yelk and white by the umbilical (omphalomeseraic) veins; on the fourth day of incubation appear two masses (which he oddly names vermiculus), one of which develops into three vesicles, to form the cerebrum, cerebellum and eyes, the other into the breastbone and thorax; on the sixth or seventh day come the viscera, and lastly, the feathers and other external parts. Harvey points out how nearly this order of development in the chick agrees with what he had observed in mammalian and particularly in human embryos. He notes the bifid apex of the foetal heart in man and the equal thickness of the ventricles, the soft cartilages which represent the future bones, the large amount of liquor amnii and absence of placenta which characterize the foetus in the third month; in the fourth the position of the testes in the abdomen, and the uterus with its Fallopian tubes resembling the uterus bicornis of the sheep; the large thymus; the caecum, small as in the adult, not forming a second stomach as in the pig, the horse and the hare; the lobulated kidneys, like those of the seal (“vitulo,” sc. marino) and porpoise, and the large suprarenal veins, not much smaller than those of the kidneys (li.-lvi). He failed, however, to trace the connexion of the urachus with the bladder. In the following chapters (lxiii.-lxxii.) he describes the process of generation in the fallow deer or the roe. After again insisting that all animals arise from ova, that a “conception” is an internal egg and an egg an extruded conception, he goes on to describe the uterus of the doe, the process of impregnation, and the subsequent development of the foetus and its membranes, the punctum saliens, the cotyledons of the placenta, and the “uterine milk,” to which Sir William Turner recalled attention in later years. The treatise concludes with detached notes on the placenta, parturition and allied subjects.

Harvey’s other Writings and Medical Practice.—The remaining writings of Harvey which are extant are unimportant. A complete list of them will be found below, together with the titles of those which we know to be lost. Of these the most important were probably that on respiration, and the records of post-mortem examinations. From the following passage (De partu, p. 550) it seems that he had a notion of respiration being connected rather with the production of animal heat than, as then generally supposed, with the cooling of the blood. “Haec qui diligenter perpenderit, naturamque aeris diligenter introspexerit, facile opinor fatebitur eundem nec refrigerationis gratia nec in pabulum animalibus concedi. Haec autem obiter duntaxat de respiratione diximus, proprio loco de eadem forsitan copiosius disceptaturi.”

Of Harvey as a practising physician we know very little. Aubrey tells us that “he paid his visits on horseback with a foot-cloth, his man following on foot, as the fashion then was.” He adds—“Though all of his profession would allow him to be an excellent anatomist, I never heard any that admired his therapeutic way. I knew several practitioners that would not have given threepence for one of his bills” (the apothecaries used to collect physicians’ prescriptions and sell or publish them to their own profit), “and that a man could hardly tell by his bill what he did aim at.” However this may have been,—and rational therapeutics was impossible when the foundation stone of physiology had only just been laid,—we know that Harvey was an active practitioner, performing such important surgical operations as the removal of a breast, and he turned his obstetric experience to account in his book on generation. Some good practical precepts as to the conduct of labour are quoted by Percivall Willughby (1596-1685). He also took notes of the anatomy of disease; these unfortunately perished with his other manuscripts. Otherwise we might regard him as a forerunner of G. B. Morgagni; for Harvey saw that pathology is but a branch of physiology, and like it must depend first on accurate anatomy. He speaks strongly to this purpose in his first epistle to Riolan: “Sicut enim sanorum et boni habitus corporum dissectio plurimum ad philosophiam et rectam physiologiam facit, ita corporum morbosorum et cachecticorum inspectio potissimum ad pathologiam philosophicam.” The only specimen we have of his observations in morbid anatomy is his account of the post-mortem examination made by order of the king on the body of the famous Thomas Parr, who died in 1635, at the reputed age of 152. Harvey insists on the value of physiological truths for their own sake, independently of their immediate utility; but he himself gives us an interesting example of the practical application of his theory of the circulation in the cure of a large tumour by tying the arteries which supplied it with blood (De generat. Exerc. xix.).

The following is believed to be a complete list of all the known writings of Harvey, published and unpublished:—

Exercitatio anatomica de motu cordis et sanguinis, 4to (Frankfort-on-the-Main, 1628); Exercitationes duae anatomicae de circulatione sanguinis, ad Johannem Riolanum, filium, Parisiensem (Cambridge, 1649); Exercitationes de generatione animalium, quibus accedunt quaedam de partu, de membranis ac humoribus uteri, et de conceptione, 4to (London, 1651); Anatomia Thomae Parr, first published in the treatise of Dr John Betts, De ortu et natura sanguinis, 8vo (London, 1669). Letters: (1) to Caspar Hoffmann of Nuremberg, May 1636; (2) to Schlegel of Hamburg, April 1651; (3) three to Giovanni Nardi of Florence, July 1651, Dec. 1653 and Nov. 1655; (4) two to Dr Morison of Paris, May 1652; (5) two to Dr Horst of Darmstadt, Feb. 1654-1655 and July 1655; (6) to Dr Vlackveld of Haarlem, May 1657. His letters to Hoffmann and Schlegel are on the circulation; those to Morison, Horst and Vlackveld refer to the discovery of the lacteals; the two to Nardi are short letters of friendship. All these letters were published by Sir George Ent in his collected works (Leiden, 1687). Of two MS. letters, one on official business to the secretary Dorchester was printed by Dr Aveling, with a facsimile of the crabbed handwriting (Memorials of Harvey, 1875), and the other, about a patient, appears in Dr Robert Willis’s Life of Harvey (1878). Praelectiones anatomiae universalis per me Gul. Harveium medicum Londinensem, anat. et chir. professorem, an. dom. (1616), aetat. 37,—MS. notes of his Lumleian lectures in Latin,—are in the British Museum library; an autotype reproduction was issued by the College of Physicians in 1886. An account of a second MS. in the British Museum, entitled Gulielmus Harveius de musculis, motu locali, &c., was published by Sir G. E. Paget (Notice of an unpublished MS. of Harvey, London, 1850). The following treatises, or notes towards them, were lost either in the pillaging of Harvey’s house, or perhaps in the fire of London, which destroyed the old College of Physicians: A Treatise on Respiration, promised and probably at least in part completed (pp. 82, 550, ed. 1766); Observationes de usu Lienis; Observationes de motu locali, perhaps identical with the above-mentioned manuscript; Tractatum physiologicum; Anatomia medicalis (apparently notes of morbid anatomy); De generatione insectorum. The fine 4to edition of Harvey’s Works, published by the Royal College of Physicians in 1766, was superintended by Dr Mark Akenside; it contains the two treatises, the account of the post-mortem examination of old Parr, and the six letters enumerated above. A translation of this volume by Dr Willis, with Harvey’s will, was published by the Sydenham Society, 8vo (London, 1849).

The following are the principal biographies of Harvey: in Aubrey’s Letters of Eminent Persons, &c., vol. ii. (London, 1813), first published in 1685, the only contemporary account; in Bayle’s Dictionnaire historique et critique (1698 and 1720; Eng. ed., 1738); in the Biographia Britannica, and in Aitken’s Biographical Memoirs; the Latin Life by Dr Thomas Lawrence, prefixed to the college edition of Harvey’s Works in 1766; memoir in Lives of British Physicians (London, 1830); a Life by Dr Robert Willis, founded on that by Lawrence, and prefixed to his English edition of Harvey in 1847; the much enlarged Life by the same author, published in 1878; the biography by Dr William Munk in the Roll of the College of Physicians, vol. i. (2nd ed., 1879).

The literature which has arisen on the great discovery of Harvey, on his methods and his merits, would fill a library. The most important contemporary writings have been mentioned above. The following list gives some of the most remarkable in modern times: the article in Bayle’s dictionary quoted above; Anatomical Lectures, by Wm. Hunter, M.D. (1784); Sprengell, Geschichte der Arzneikunde (Halle, 1800), vol. iv.; Flourens, Histoire de la circulation (1854); Lewes, Physiology of Common Life (1859), vol. i. pp. 291-345; Ceradini, La Scoperta della circolazione del sangue (Milan, 1876); Tollin, Die Entdeckung des Blutkreislaufs durch Michael Servet (Jena, 1876); Kirchner, Die Entdeckung des Blutkreislaufs (Berlin, 1878); Willis, in his Life of Harvey; Wharton Jones, “Lecture on the Circulation of the Blood,” Lancet for Oct. 25 and Nov. 1, 1879; and the various Harveian Orations, especially those by Sir E. Sieveking, Dr Guy and Professor George Rolleston.

(P. H. P.-S.)

1 “Ignoscant mihi niveae animae, si, summarum injuriarum memor, levem gemitum effudero. Doloris mihi haec causa est: cum, inter nuperos nostros tumultus et bella plusquam civilia, serenissimum regem (idque non solum senatus permissione sed et jussu) sequor, rapaces quaedam manus non modo aedium mearum supellectilem omnem expilarunt, sed etiam, quae mihi causa gravior querimoniae, adversaria mea, multorum annorum laboribus parta, e museo meo summoverunt. Quo factum est ut observationes plurimae, praesertim de generatione insectorum, cum republicae literariae (ausim dicere) detrimento, perierint.”—De gen., Ex. lxviii. To this loss Cowley refers—

“O cursed war! who can forgive thee this? Houses and towns may rise again, And ten times easier ’tis To rebuild Paul’s than any work of his.”

2 Indeed the same word, περίοδος αἵματος, occurs in the Hippocratic writings, and was held by Van der Linden to prove that to the father of medicine himself, and not to Columbus or Caesalpinus, belonged the laurels of Harvey.

3 Realdo Columbus (De re anatomica, 1559) formally denies the muscularity of the heart, yet correctly teaches that blood and spirits pass from the right to the left ventricle, not through the septum but through the lungs, “quod nemo hactenus aut animadvertit aut scriptum reliquit.” The fact that Harvey quotes Columbus and not Servetus is explained by the almost entire destruction of the writings of the latter, which are now among the rarest curiosities. The great anatomist Fabricius, Harvey’s teacher at Padua, described the valves of the veins more perfectly than had Sylvius. Carlo Ruini, in his treatise on the Anatomy and Diseases of the Horse (1590), taught that the left ventricle sends blood and vital spirits to all parts of the body except the lungs—the ordinary Galenical doctrine. Yet on the strength of this phrase Professor J. B. Ercolani actually put up a tablet in the veterinary school at Bologna to Ruini as the discoverer of the circulation of the blood! The claims of Caesalpinus, a more plausible claimant to Harvey’s laurels, are scarcely better founded. In his Quaestiones peripateticae (1571) he followed Servetus and Columbus in describing what we now know as the pulmonary “circulation” under that name, and this is the only foundation for the assertion (first made in Bayle’s dictionary) that Caesalpinus knew “the circulation of the blood.” He is even behind Servetus, for he only allows part of the blood of the right ventricle to go round by this “circuit”; some, he conceives, passes through the hypothetical pores in the septum, and the rest by the superior cava to the head and arms, by the inferior to the rest of the body: “Hanc esse venarum utilitatem ut omnes partes corporis sanguinem pro nutrimento deferant. Ex dextro ventr° cordis vena cava sanguinem crassiorem, in quo calor intensus est magis, ex altero autern ventr°, sanguinem temperatissimum ac sincerissimum habente, egreditur aorta.” Caesalpinus seems to have had no original views on the subject; all that he writes is copied from Galen or from Servetus except some erroneous observations of his own. His greatest merit was as a botanist; and no claim to the “discovery of the circulation” was made by him or by his contemporaries. When it was made, Haller decided conclusively against it. The fact that an inscription has been placed on the bust of Caesalpinus at Rome, which states that he preceded others in recognizing and demonstrating “the general circulation of the blood,” is only a proof of the blindness of misplaced national vanity.

Nempe agnoscimus Deum, creatorem summum atque omnipotentem, in cunctorum animalium fabrica ubique praesentem esse, et in operibus suis quasi digito monstrari: cujus in procreatione pulli instrumenta sint gallus et gallina.... Nec cuiquam sane haec attributa conveniunt nisi omnipotenti rerum Principio, quocunque demum nomine idipsum appellare libuerit: sive Mentem divinam cum Aristotele, sive cum Platone Animam Mundi, aut cum aliis Naturam naturantem, vel cum ethnicis Saturnum aut Iovem; vel potius (ut nos decet) Creatorem ac Patrem omnium quae in coelis et terris, a quo animalia eorumque origines dependent, cujusque nutu sive effatu fiunt et generantur omnia.”

HARVEY, a city of Cook county, Illinois, U.S.A., about 18 m. S. of the Chicago Court House. Pop. (1900) 5395 (982 foreign-born); (1910) 7227. It is served by the Chicago Terminal Transfer, the Grand Trunk and the Illinois Central railways. Harvey is a manufacturing and residence suburb of Chicago. Among its manufactures are railway, foundry and machine-shop supplies, mining and ditching machinery, stone crushers, street-making and street-cleaning machinery, stoves and motor-vehicles. It was named in honour of Turlington W. Harvey, a Chicago capitalist, founded in 1890, incorporated as a village in 1891 and chartered as a city in 1895.

HARWICH, a municipal borough and seaport in the Harwich parliamentary division of Essex, England, on the extremity of a small peninsula projecting into the estuary of the Stour and Orwell, 70 m. N.E. by E. of London by the Great Eastern railway. Pop. (1901), 10,070. It occupies an elevated situation, and a wide view is obtained from Beacon Hill at the southern end of the esplanade. The church of St Nicholas was built of brick in 1821; and there are a town hall and a custom-house. The harbour is one of the best on the east coast of England, and in stormy weather is largely used for shelter. A breakwater and sea-wall prevent the blocking of the harbour entrance and encroachments of the sea; and there is another breakwater at Landguard Point on the opposite (Suffolk) shore of the estuary. The principal imports are grain and agricultural produce, timber and coal, and the exports cement and fish. Harwich is one of the principal English ports for continental passenger traffic, steamers regularly serving the Hook of Holland, Amsterdam, Rotterdam, Antwerp, Esbjerg, Copenhagen and Hamburg. The continental trains of the Great Eastern railway run to Parkeston Quay, 1 m. from Harwich up the Stour, where the passenger steamers start. The fisheries are important, principally those for shrimps and lobsters. There are cement and shipbuilding works. The port is the headquarters of the Royal Harwich Yacht Club. There are batteries at and opposite Harwich, and modern works on Shotley Point, at the fork of the two estuaries. There are also several of the Martello towers of the Napoleonic era. At Landguard Fort there are important defence works with heavy modern guns commanding the main channel. This has been a point of coast defence since the time of James I. Between the Parkeston Quay and Town railway stations is that of Dovercourt, an adjoining parish and popular watering-place. Harwich is under a mayor, 4 aldermen and 12 councillors. Area, 1541 acres.

Harwich (Herewica, Herewyck) cannot be shown to have been inhabited very early, although in the 18th century remains of a camp, possibly Roman, existed there. Harwich formed part of the manor of Dovercourt. It became a borough in 1319 by a charter of Edward II., which was confirmed in 1342 and 1378, and by each of the Lancastrian kings. The exact nature and degree of its self-government is not clear. Harwich received charters in 1547, 1553 and 1560. In 1604 James I. gave it a charter which amounted to a new constitution, and from this charter begins the regular parliamentary representation. Two burgesses had attended parliament in 1343, but none had been summoned since. Until 1867 Harwich returned two members; it then lost one, and in 1885 it was merged in the county. Included in the manor of Dovercourt, Harwich from 1086 was for long held by the de Vere family. In 1252 Henry III. granted to Roger Bigod a market here every Tuesday, and a fair on Ascension day, and eight days after. In 1320 a grant occurs of a Tuesday market, but no fair is mentioned. James I. granted a Friday market, and two fairs, at the feast of St Philip and St James, and on St Luke’s day. The fair has died out, but markets are still held on Tuesday and Friday. Harwich has always had a considerable trade; in the 14th century merchants came even from Spain, and there was much trade in wheat and wool with Flanders. But the passenger traffic appears to have been as important at Harwich in the 14th century as it is now. Shipbuilding was a considerable industry at Harwich in the 17th century.

HARZBURG, a town of Germany, in the duchy of Brunswick, beautifully situated in a deep and well-wooded vale at the north foot of the Harz Mountains, at the terminus of the Brunswick-Harzburg railway, 5 m. E.S.E. from Goslar and 18 m. S. from Wolfenbüttel. Pop. (1905), 4396. The Radau, a mountain stream, descending from the Brocken, waters the valley and adds much to its picturesque charm. The town is much frequented as a summer residence. It possesses brine and carbonated springs, the Juliushall saline baths being about a mile to the south of the town, and a hydropathic establishment. A mile and a half south from the town lies the Burgberg, 1500 ft. above sea-level, on whose summit, according to tradition, was once an altar to the heathen idol Krodo, still to be seen in the Ulrich chapel at Goslar. There are on the summit of the hill the remains of an old castle, and a monument erected in 1875 to Prince Bismarck, with an inscription taken from one of his speeches against the Ultramontane claims of Rome—“Nach Canossa gehen wir nicht.”

The castle on the Burgberg called the Harzburg is famous in German history. It was built between 1065 and 1069, but was laid in ruins by the Saxons in 1074; again it was built and again destroyed during the struggle between the emperor Henry IV. and the Saxons. By Frederick I. it was granted to Henry the Lion, who caused it to be rebuilt about 1180. It was a frequent residence of Otto IV., who died therein, and after being frequently besieged and taken, it passed to the house of Brunswick. It ceased to be of importance as a fortress after the Thirty Years’ War, and gradually fell into ruins.

See Delius, Untersuchungen über die Geschichte der Harzburg (Halberstadt, 1826); Dommes, Harzburg und seine Umgebung (Goslar, 1862); Jacobs, Die Harzburg und ihre Geschichte (1885); and Stolle, Führer von Bad Harzburg (1899).

HARZ MOUNTAINS (also spelt Hartz, Ger. Harzgebirge, anc. Silva Hercynia), the most northerly mountain-system of Germany, situated between the rivers Weser and Elbe, occupy an area of 784 sq. m., of which 455 belong to Prussia, 286 to Brunswick and 43 to Anhalt. Their greatest length extends in a S.E. and N.W. direction for 57 m., and their maximum breadth is about 20 m. The group is made up of an irregular series of terraced plateaus, rising here and there into rounded summits, and intersected in various directions by narrow, deep valleys. The north-western and higher part of the mass is called the Ober or Upper Harz; the south-eastern and more extensive part, the Unter or Lower Harz; while the N.W. and S.W. slopes of the Upper Harz form the Vorharz. The Brocken group, which divides the Upper and Lower Harz, is generally regarded as belonging to the first. The highest summits of the Upper Harz are the Brocken (3747 ft.), the Heinrichshöhe (3425 ft.), the Königsberg (3376 ft.) and the Wurmberg (3176 ft.); of the Lower Harz, the Josephshöhe in the Auerberg group and the Viktorhöhe in the Ramberg, each 1887 ft. Of these the Brocken (q.v.) is celebrated for the legends connected with it, immortalized in Goethe’s Faust. Streams are numerous, but all small. While rendered extensively useful, by various skilful artifices, in working the numerous mines of the district, at other parts of their course they present the most picturesque scenery in the Harz. Perhaps the finest valley is the rocky Bodethal, with the Rosstrappe, the Hexentanzplatz, the Baumannshöhle and the Bielshöhle.

The Harz is a mass of Palaeozoic rock rising through the Mesozoic strata of north Germany, and bounded on all sides by faults. Slates, schists, quartzites and limestones form the greater part of the hills, but the Brocken and Victorshöhe are masses of intrusive granite, and diabases and diabase tuffs are interstratified with the sedimentary deposits. The Silurian, Devonian and Carboniferous systems are represented—the Silurian and Devonian forming the greater part of the hills S.E. of a line drawn from Lauterberg to Wernigerode, while N.W. of this line the Lower Carboniferous predominates. A few patches of Upper Carboniferous are found on the borders of the hills near Ilfeld, Ballenstedt, &c., lying unconformably upon the Devonian. The structure of the Harz is very complicated, but the general strike of the folds, especially in the Oberharz plateau, is N.E. or N.N.E. The whole mass evidently belongs to the ancient Hercynian chain of North Europe (which, indeed, derives its name from the Harz), and is the north-easterly continuation of the rocks of the Ardennes and the Eifel. The folding of the old rocks took place towards the close of the Palaeozoic era; but the faulting to which they owe their present position was probably Tertiary. Metalliferous veins are common, amongst the best-known being the silver-bearing lead veins of Klausthal, which occur in the Culm or Lower Carboniferous.

Owing to its position as the first range which the northerly winds strike after crossing the north German plain, the climate on the summit of the Harz is generally raw and damp, even in summer. In 1895 an observatory was opened on the top of the Brocken, and the results of the first five years (1806-1900) showed a July mean of 50° Fahr., a February mean of 24.7°, and a yearly mean of 36.6°. During the same five years the rainfall averaged 641⁄3 ins. annually. But while the summer is thus relatively ungenial on the top of the Harz, the usual summer heat of the lower-lying valleys is greatly tempered and cooled; so that, adding this to the natural attractions of the scenery, the deep forests, and the legendary and romantic associations attaching to every fantastic rock and ruined castle, the Harz is a favourite summer resort of the German people. Among the more popular places of resort are Harzburg, Thale and the Bodethal; Blankenburg, with the Teufelsmauer and the Hermannshöhle; Wernigerode, Ilsenburg, Grund, Lauterberg, Hubertusbad, Alexisbad and Suderode. Some of these, and other places not named, add to their natural attractions the advantage of mineral springs and baths, pine-needle baths, whey cures, &c. The Harz is penetrated by several railways, among them a rack-railway up the Brocken, opened in 1898. The district is traversed by excellent roads in all directions.

The northern summits are destitute of trees, but the lower slopes of the Upper Harz are heavily wooded with pines and firs. Between the forests of these stretch numerous peat-mosses, which contain in their spongy reservoirs the sources of many small streams. On the Brocken are found one or two arctic and several alpine, plants. In the Lower Harz the forests contain a great variety of timber. The oak, elm and birch are common, while the beech especially attains an unusual size and beauty. The walnut-tree grows in the eastern districts.

The last bear was killed in the Harz in 1705, and the last lynx in 1817, and since that time the wolf too has become extinct; but deer, foxes, wild cats and badgers are still found in the forests.

The Harz is one of the richest mineral storehouses in Germany, and the chief industry is mining, which has been carried on since the middle of the 10th century. The most important mineral is a peculiarly rich argentiferous lead, but gold in small quantities, copper, iron, sulphur, alum and arsenic are also found. Mining is carried on principally at Klausthal and St Andreasberg in the Upper Harz. Near the latter is one of the deepest mining shafts in Europe, namely the Samson, which goes down 2790 ft. or 720 ft. below sea-level. For the purpose of getting rid of the water, and obviating the flooding of such deep workings, it has been found necessary to construct drainage works of some magnitude. As far back as 1777-1799 the Georgsstollen was cut through the mountains from the east of Klausthal westward to Grund, a distance of 4 m.; but this proving insufficient, another sewer, the Ernst-Auguststollen, no less than 14 m. in length, was made from the same neighbourhood to Gittelde, at the west side of the Harz, in 1851-1864. Marble, granite and gypsum are worked; and large quantities of vitriol are manufactured. The vast forests that cover the mountain slopes supply the materials for a considerable trade in timber. Much wood is exported for building and other purposes, and in the Harz itself is used as fuel. The sawdust of the numerous mills is collected for use in the manufacture of paper. Turf-cutting, coarse lace-making and the breeding of canaries and native song-birds also occupy many of the people. Agriculture is carried on chiefly on the plateaus of the Lower Harz; but there is excellent pasturage both in the north and in the south. In the Lower Harz, as in Switzerland, the cows, which carry bells harmoniously tuned, are driven up into the heights in early summer, returning to the sheltered regions in late autumn.

The inhabitants are descended from various stocks. The Upper and Lower Saxon, the Thuringian and the Frankish races have all contributed to form the present people, and their respective influences are still to be traced in the varieties of dialect. The boundary line between High and Low German passes through the Harz. The Harz was the last stronghold of paganism in Germany, and to that fact are due the legends, in which no district is richer, and the fanciful names given by the people to peculiar objects and appearances of nature.

HASA, EL (Ahsa, Al Hasa), a district in the east of Arabia stretching along the shore of the Persian Gulf from Kuwét in 29° 20′ N. to the south point of the Gulf of Bahrein in 25° 10′ N., a length of about 360 m. On the W. it is bounded by Nejd, and on the S.E. by the peninsula of El Katr which forms part of Oman. The coast is low and flat and has no deep-water port along its whole length with the exception of Kuwét; from that place to El Katif the country is barren and without villages or permanent settlements, and is only occupied by nomad tribes, of which the principal are the Bani Hajar, Ajman and Khālid. The interior consists of low stony ridges rising gradually to the inner plateau. The oases of Hofuf and Katif, however, form a strong contrast to the barren wastes that cover the greater part of the district. Here an inexhaustible supply of underground water (to which the province owes its name Hasa) issues in strong springs, marking, according to Arab geographers, the course of a great subterranean river draining the Nejd highlands. Hofuf the capital, a town of 15,000 to 20,000 inhabitants, with its neighbour Mubāriz scarcely less populous, forms the centre of a thriving district 50 m. long by 15 m. in breadth, containing numerous villages each with richly cultivated fields and gardens. The town walls enclose a space of 1½ by 1 m., at the north-west angle of which is a remarkable citadel attributed to the Carmathian princes. Mubāriz is celebrated for its hot spring, known as Um Sabā or “mother of seven,” from the seven channels by which its water is distributed. Beyond the present limits of the oasis much of the country is well supplied with water, and ruined sites and half-obliterated canals show that it has only relapsed into waste in recent times. Cultivation reappears at Katif, a town situated on a small bay some 35 m. north-west of Bahrein. Date groves extend for several miles along the coast, which is low and muddy. The district is fertile but the climate is hot and unhealthy; still, owing to its convenient position, the town has a considerable trade with Bahrein and the gulf ports on one side and the interior of Nejd on the other. The fort is a strongly built enclosure attributed, like that at Hofuf, to the Carmathian prince Abu Tahir.

‘Uker or ‘Ujer is the nearest port to Hofuf, from which it is distant about 40 m.; large quantities of rice and piece goods transhipped at Bahrein are landed here and sent on by caravan to Hofuf, the great entrepôt for the trade between southern Nejd and the coast. It also shares in the valuable pearl fishery of Bahrein and the adjacent coast.

Politically El Hasa is a dependency of Turkey, and its capital Hofuf is the headquarters of the sanjak or district of Nejd. Hofuf, Katif and El Katr were occupied by Turkish garrisons in 1871, and the occupation has been continued in spite of British protest as to El Katr, which according to the agreement made in 1867, when Bahrein was taken under British protection, was tributary to the latter. Turkish claims to Kuwēt have not been admitted by Great Britain.

ḤASAN and ḤOSAIN (or Ḥusein), sons of the fourth Mahommedan caliph Ali by his wife Fatima, daughter of Mahomet. On Ali’s death Ḥasan was proclaimed caliph, but the strength of Moawiya who had rebelled against Ali was such that he resigned his claim on condition that he should have the disposal of the treasure stored at Kufa, with the revenues of Darabjird. This secret negotiation came to the ears of Ḥasan’s supporters, a mutiny broke out and Ḥasan was wounded. He retired to Medina where he died about 669. The story that he was poisoned at Moawiya’s instigation is generally discredited (see Caliphate, sect. B, § 1). Subsequently his brother Ḥosain was invited by partisans in Kufa to revolt against Moawiya’s successor Yazid. He was, however, defeated and killed at Kerbela on the 10th of October (Muharram) 680 (see Caliphate, sect. B, § 2 ad init.). Ḥosain is the hero of the Passion Play which is performed annually (e.g. at Kerbela) on the anniversary of his death by the Shi’ites of Persia and India, to whom from the earliest times the family of Ali are the only true descendants of Mahomet. The play lasts for several days and concludes with the carrying out of the coffins (tabūt) of the martyrs to an open place in the neighbourhood.

ḤASAN UL-BAṢRĪ [Abū Sa‘ūd ul-Ḥasan ibn Abī-l-Ḥasan Yassār ul-Baṣrī], (642-728 or 737), Arabian theologian, was born at Medina. His father was a freedman of Zaid ibn Thābit, one of the Anṣār (Helpers of the Prophet), his mother a client of Umm Salama, a wife of Mahomet. Tradition says that Umm Salama often nursed Ḥasan in his infancy. He was thus one of the Tābi‘ūn (i.e. of the generation that succeeded the Helpers). He became a teacher of Baṣra and founded a school there. Among his pupils was Wāṣil ibn ‘Atā, the founder of the Mo‘tazilites. He himself was a great supporter of orthodoxy and the most important representative of asceticism in the time of its first development. With him fear is the basis of morality, and sadness the characteristic of his religion. Life is only a pilgrimage, and comfort must be denied to subdue the passions. Many writers testify to the purity of his life and to his excelling in the virtues of Mahomet’s own companions. He was “as if he were in the other world.” In politics, too, he adhered to the earliest principles of Islam, being strictly opposed to the inherited caliphate of the Omayyads and a believer in the election of the caliph.

His life is given in Nawāwī’s Biographical Dictionary (ed. F. Wüstenfeld, Göttingen, 1842-1847). Cf. R. Dozy, Essai sur l’histoire de l’islamisme, pp. 201 sqq. (Leiden and Paris, 1879); A. von Kremer, Culturgeschichtliche Streifzüge, p. 5 seq.; R. A. Nicholson, A Literary History of the Arabs, pp. 225-227 (London, 1907).

HASBEYA, or Hasbeiya, a town of the Druses, about 36 m. W. of Damascus, situated at the foot of Mt. Hermon in Syria, overlooking a deep amphitheatre from which a brook flows to the Hasbāni. The population is about 5000 (4000 Christians). Both sides of the valley are planted in terraces with olives, vines and other fruit trees. The grapes are either dried or made into a kind of syrup. In 1846 an American Protestant mission was established in the town. This little community suffered much persecution at first from the Greek Church, and afterwards from the Druses, by whom in 1860 nearly 1000 Christians were massacred, while others escaped to Tyre or Sidon. The castle in Hasbeya was held by the crusaders under Count Oran; but in 1171 the Druse emirs of the great Shehāb family (see Druses) recaptured it. In 1205 this family was confirmed in the lordship of the town and district, which they held till the Turkish authorities took possession of the castle in the 19th century. Near Hasbeya are bitumen pits let by the government; and to the north, at the source of the Hasbāni, the ground is volcanic. Some travellers have attempted to identify Hasbeya with the biblical Baal-Gad or Baal-Hermon.

ḤASDAI IBN SHAPRUT, the founder of the new culture of the Jews in Moorish Spain in the 10th century. He was both physician and minister to Caliph Abd ar-Raḥman III. in Cordova. A man of wide learning and culture, he encouraged the settlement of Jewish scholars in Andalusia, and his patronage of literature, science and art promoted the Jewish renaissance in Europe. Poetry, philology, philosophy all flourished under his encouragement, and his name was handed down to posterity as the first of the many Spanish Jews who combined diplomatic skill with artistic culture. This type was the creation of the Moors in Andalusia, and the Jews ably seconded the Mahommedans in the effort to make life at once broad and deep.

HASDEU, or Hăjdeu, BOGDAN PETRICEICU (1836-1907), Rumanian philologist, was born at Khotin in Bessarabia in 1836, and studied at the university of Kharkov. In 1858 he first settled in Jassy as professor of the high school and librarian. He may be considered as the pioneer in many branches of Rumanian philology and history. At Jassy he started his Archiva historica a Romaniei (1865-1867), in which a large number of old documents in Slavonic and Rumanian were published for the first time. In 1870 he inaugurated Columna lui Traian, the best philological review of the time in Rumania. In his Cuvente den Bătrăni (2 vols., 1878-1881) he was the first to contribute to the history of apocryphal literature in Rumania. His Historia critica a Romanilor (1875), though incomplete, marks the beginning of critical investigation into the history of Rumania. Hasdeu edited the ancient Psalter of Coresi of 1577 (Psaltirea lui Coresi, 1881). His Etymologicum magnum Romaniae (1886, &c.) is the beginning of an encyclopaedic dictionary of the Rumanian language, though never finished beyond the letter B. In 1876 he was appointed director of the state archives in Bucharest and in 1878 professor of philology at the university of Bucharest. His works, which include one drama, Rasvan şi Vidra, bear the impress of great originality of thought, and the author is often carried away by his profound erudition and vast imagination. Hasdeu was a keen politician. After the death of his only child Julia in 1888 he became a mystic and a strong believer in spiritism. He died at Campina on the 7th of September 1907.

HASDRUBAL, the name of several Carthaginian generals, among whom the following are the most important:—

1. The son-in-law of Hamilcar Barca (q.v.), who followed the latter in his campaign against the governing aristocracy at Carthage at the close of the First Punic War, and in his subsequent career of conquest in Spain. After Hamilcar’s death (228) Hasdrubal, who succeeded him in the command, extended the newly acquired empire by skilful diplomacy, and consolidated it by the foundation of New Carthage (Cartagena) as the capital of the new province, and by a treaty with Rome which fixed the Ebro as the boundary between the two powers. In 221 he was killed by an assassin.

Polybius ii. 1; Livy xxi. 1; Appian, Hispanica, 4-8.

2. The second son of Hamilcar Barca, and younger brother of Hannibal. Left in command of Spain when Hannibal departed to Italy (218), he fought for six years against the brothers Gnaeus and Publius Scipio. He had on the whole the worst of the conflict, and a defeat in 216 prevented him from joining Hannibal in Italy at a critical moment; but in 212 he completely routed his opponents, both the Scipios being killed. He was subsequently outgeneralled by Publius Scipio the Younger, who in 209 captured New Carthage and gained other advantages. In the same year he was summoned to join his brother in Italy. He eluded Scipio by crossing the Pyrenees at their western extremity, and, making his way thence through Gaul and the Alps in safety, penetrated far into Central Italy (207). He was ultimately checked by two Roman armies, and being forced to give battle was decisively defeated on the banks of the Metaurus. Hasdrubal himself fell in the fight; his head was cut off and thrown into Hannibal’s camp as a sign of his utter defeat.

HASE, CARL BENEDICT (1780-1864), French Hellenist, of German extraction, was born at Sulza near Naumburg on the 11th of May 1780. Having studied at Jena and Helmstedt, in 1801 he made his way on foot to Paris, where he was commissioned by the comte de Choiseul-Gouffier, late ambassador to Constantinople, to edit the works of Johannes Lydus from a MS. given to Choiseul by Prince Mourousi. Hase thereupon decided to devote himself to Byzantine history and literature, on which he became the acknowledged authority. In 1805 he obtained an appointment in the MSS. department of the royal library; in 1816 became professor of palaeography and modern Greek at the École Royale, and in 1852 professor of comparative grammar in the university. In 1812 he was selected to superintend the studies of Louis Napoleon (afterwards Napoleon III.) and his brother. He died on the 21st of March 1864. His most important works are the editions of Leo Diaconus and other Byzantine writers (1819), and of Johannes Lydus, De ostentis (1823), a masterpiece of textual restoration, the difficulties of which were aggravated by the fact that the MS. had for a long time been stowed away in a wine-barrel in a monastery. He also edited part of the Greek authors in the collection of the Historians of the Crusades and contributed many additions (from the fathers, medical and technical writers, scholiasts and other sources) to the new edition of Stephanus’s Thesaurus.

See J. D. Guigniaut, Notice historique sur la vie et les travaux de Carl Benedict Hase (Paris, 1867); articles in Nouvelle Biographie générale and Allgemeine deutsche Biographie; and a collection of autobiographical letters, Briefe von der Wanderung und aus Paris, edited by O. Heine (1894), containing a vivid account of Hase’s journey, his enthusiastic impressions of Paris and the hardships of his early life.

HASE, KARL AUGUST VON (1800-1890), German Protestant theologian and Church historian, was born at Steinbach in Saxony on the 25th of August 1800. He studied at Leipzig and Erlangen, and in 1829 was called to Jena as professor of theology. He retired in 1883 and was made a baron. He died at Jena on the 3rd of January 1890. Hase’s aim was to reconcile modern culture with historical Christianity in a scientific way. But though a liberal theologian, he was no dry rationalist. Indeed, he vigorously attacked rationalism, as distinguished from the rational principle, charging it with being unscientific inasmuch as it ignored the historical significance of Christianity, shut its eyes to individuality and failed to give religious feeling its due. His views are presented scientifically in his Evangelisch-protestantische Dogmatik (1826; 6th ed., 1870), the value of which “lies partly in the full and judiciously chosen historical materials prefixed to each dogma, and partly in the skill, caution and tact with which the permanent religious significance of various dogmas is discussed” (Otto Pfleiderer). More popular in style is his Gnosis oder prot.-evang. Glaubenslehre (3 vols., 1827-1829; 2nd ed. in 2 vols., 1869-1870). But his reputation rests chiefly on his treatment of Church history in his Kirchengeschichte, Lehrbuch zunächst für akademische Vorlesungen (1834, 12th ed., 1900).

His biographical studies, Franz von Assisi (1856; 2nd ed., 1892), Katerina von Siena (1864; 2nd ed., 1892), Neue Propheten (Die Jungfrau von Orleans, Savonarola, Thomas Münzer) are judicious and sympathetic. Other works are: Hutterus redivivus oder Dogmatik der evang.-luth. Kirche (1827; 12th ed., 1883), in which he sought to present the teaching of the Protestant church in such a way as Hutter would have reconstructed it, had he still been alive; Leben Jesu (1829; 5th ed., 1865; Eng. trans., 1860); in an enlarged form, Geschichte Jesu (2nd ed., 1891); and Handbuch der prot. Polemik gegen die röm.-kath. Kirche (1862; 7th ed., 1900; Eng. trans., 1906).

For his life see his Ideale und Irrtümer (1872; 5th ed., 1894) and Annalen meines Lebens (1891); and cf. generally Otto Pfleiderer, Development of Theology (1890); F. Lichtenberger, Hist. of German Theology (1889).

HASHISH, or Hasheesh, the Arabic name, meaning literally “dried herb,” for the various preparations of the Indian hemp plant (Cannabis indica), used as a narcotic or intoxicant in the East, and either smoked, chewed or drunk (see Hemp and Bhang). From the Arabic hashīshīn, i.e. “hemp-eaters,” comes the English “assassin” (see Assassin).

HASLEMERE, a market-town in the Guildford parliamentary division of Surrey, England, 43 m. S.W. from London by the London & South-Western railway. It is situated in an elevated valley between the bold ridges of Hindhead (895 ft.) and Blackdown (918 ft.). Their summits are open and covered with heath, but their flanks and the lower ground are magnificently wooded. The hills are deeply scored by steep and picturesque valleys, of which the most remarkable is the Devil’s Punch Bowl, a hollow of regular form on the west flank of Hindhead. The invigorating air has combined with scenic attraction to make the district a favourite place of residence. Professor Tyndall built a house on the top of Hindhead, setting an example followed by many others. On Blackdown, closely screened by plantations, is Aldworth, built for Alfred, Lord Tennyson, who died here in 1892. George Eliot stayed for a considerable period at Shottermill, a neighbouring village. Pop. of Haslemere (1901), 2614; of Hindhead, 666.

HASLINGDEN, a market-town and municipal borough in the Rossendale and Heywood parliamentary divisions of Lancashire, England, 19 m. N. by W. from Manchester by the Lancashire & Yorkshire railway. Pop. (1901), 18,543. It lies in a hilly district on the borders of the forest of Rossendale, and is supposed by some to derive its name from the hazel trees which formerly abounded in its neighbourhood. The old town stood on the slope of a hill, but the modern part has extended about its base. The parish church of St James was rebuilt in 1780, with the exception of the tower, which dates from the time of Henry VIII. The woollen manufacture was formerly the staple. The town, however, steadily increasing in importance, has cotton, woollen and engineering works—coal-mining, quarrying and brickmaking are carried on in the neighbourhood. The borough, as incorporated in 1891, comprised several townships and parts of townships, but under the Local Government Act of 1894 these were united into one civil parish. The corporation consists of a mayor, 6 aldermen and 18 councillors. Area, 8196 acres.

HASPE, a town of Germany, in the Prussian province of Westphalia, in the valley of the Ennepe, at the confluence of the Hasper, and on the railway from Düsseldorf to Dortmund, 10 m. N.E. of Barmen by rail. Pop. (1905), 19,813. Its industries include iron foundries, rolling mills, puddling furnaces, and manufactures of iron, steel and brass wares and of machines. Haspe was raised to the rank of a town in 1873.

HASSAM, CHILDE (1859- ), American figure and landscape painter, born in Boston, Massachusetts, was a pupil of Boulanger and Lefebvre in Paris. He soon fell under the influence of the Impressionists, and took to painting in a style of his own, in brilliant colour, with effective touches of pure pigment. He won a bronze medal at the Paris Exhibition of 1889; medals at the World’s Fair, Chicago, 1893; Boston Art Club, 1896; Philadelphia Art Club, 1892; Carnegie Institute, Pittsburg, 1898; Buffalo Pan-American, 1901; Temple gold medal, Pennsylvania Academy of Fine Arts, Philadelphia, 1899; and silver medal, Paris Exhibition, 1900. He became a member of the National Academy of Design, the Society of American Artists, the Ten Americans, the American Water Colour Society, the Société Nationale des Beaux Arts, Paris, and the Secession Society, Munich.

HASSAN, a town and district of Mysore, India. The town dates from the 11th century and had in 1901 a population of 8241. The district naturally divides into two portions, the Malnad, or hill country, which includes some of the highest ranges of the Western Ghats, and the Maidan or plain country, sloping towards the south. The Hemavati, which flows into the Cauvery in the extreme south, is the most important river of the district. The upper slopes of the Western Ghats are abundantly clothed with magnificent forests, and wild animals abound. Among the mineral products are kaolin, felspar and quartz. The soil of the valleys is a rich red alluvial loam. The area is 2547 sq. m. Population (1901), 568,919, showing an increase of 11% in the decade. The district contains some of the most remarkable archaeological monuments in India, such as the colossal Jain image at Sravana Belgola (a monolith 57 ft. high on the summit of a hill) and the great temple at Halebid. Coffee cultivation has been on the increase of late years. The first plantation was opened in 1843, and now there are many coffee estates owned by Europeans and also native holdings. The exports are large, consisting chiefly of food-grains and coffee. The imports are European piece-goods, hardware of all sorts and spices. The largest weekly fair is held at Alur. A great annual religious gathering and fair, attended by about 10,000 persons, takes place every year at Melukot. The Southern Mahratta railway traverses the north-east of the district.

The real history of Hassan does not begin until the epoch of the Hoysala dynasty, which lasted from the 11th till the 14th century. Their capital was at Dwarasamundra (Dwaravati-pura), the ruins of which are still to be seen scattered round the village of Halebid. The earlier kings professed the Jain faith, but the finest temples were erected to Siva by the later monarchs of the line. While they were at the zenith of their power the whole of southern India acknowledged their sway.

HASSANĪA, an African tribe of Semitic stock. They inhabit the desert between Merawi and the Nile at the 6th Cataract, and the left bank of the Blue Nile immediately south of Khartum.

HASSĀN IBN THĀBIT (died 674), Arabian poet, was born in Yathrib (Medina), a member of the tribe Khazraj. In his youth he travelled to Hira and Damascus, then settled in Medina, where, after the advent of Mahomet, he accepted Islam and wrote poems in defence of the prophet. His poetry is regarded as commonplace and lacking in distinction.

His diwan has been published at Bombay (1864), Tunis (1864) and Lahore (1878). See H. Hirschfeld’s “Prolegomena to an edition of the Diwan of Hassan” in Transactions of Oriental Congress (London, 1892).

HASSE, JOHANN ADOLPH (1699-1783), German musical composer, was born at Bergedorf near Hamburg, on the 25th of March 1699, and received his first musical education from his father. Being possessed of a fine tenor voice, he chose the theatrical career, and joined the operatic troupe conducted by Reinhard Keiser, in whose orchestra Handel had played the second violin some years before. Hasse’s success led to an engagement at the court theatre of Brunswick, and it was there that, in 1723, he made his début as a composer with the opera Antigonus. The success of this first work induced the duke to send Hasse to Italy for the completion of his studies, and in 1724 he went to Naples and placed himself under Porpora, with whom, however, he seems to have disagreed both as a man and as an artist. On the other hand he gained the friendship of Alessandro Scarlatti, to whom he owed his first commission for a serenade for two voices, sung at a family celebration of a wealthy merchant by two of the greatest singers of Italy, Farinelli and Signora Tesi. This event established Hasse’s fame; he soon became very popular, and his opera Sesostrato, written for the Royal Opera at Naples in 1726, made his name known all over Italy. At Venice, where he went in 1727, he became acquainted with the celebrated singer Faustina Bordogni (born at Venice in 1700), who became the composer’s wife in 1730. The two artists soon afterwards went to Dresden, in compliance with a brilliant offer made to them by the splendour-loving elector of Saxony, Augustus II. There Hasse remained for two years, after which he again journeyed to Italy, and also in 1733 to London, in which latter city he was tempted by the aristocratic clique inimical to Handel to become the rival and antagonist of that great master. But this he modestly and wisely declined, remaining in London only long enough to superintend the rehearsals for his opera Artaserse (first produced at Venice, 1730). All this while Faustina had remained at Dresden, the declared favourite of the public and unfortunately also of the elector, nor was her husband, who remained attached to her, allowed to see her except at long intervals. In 1739, after the death of Augustus II., Hasse settled permanently at Dresden till 1763, when he and his wife retired from court service with considerable pensions. But Hasse was still too young to rest on his laurels. He went with his family to Vienna, and added several operas to the great number of his works already in existence. His last work for the stage was the opera Ruggiero (1771), written for the wedding of Archduke Ferdinand at Milan. On the same occasion a work by Mozart, then fourteen years old, was performed, and Hasse observed “this youngster will surpass us all.” By desire of his wife Hasse settled at her birthplace Venice, and there he died on the 23rd of December 1783. His compositions include as many as 120 operas, besides oratorios, cantatas, masses, and almost every variety of instrumental music. During the siege of Dresden by the Prussians in 1760, most of his manuscripts, collected for a complete edition to be brought out at the expense of the elector, were burnt. Some of his works, amongst them an opera Alcide al Bivio (1760), have been published, and the libraries of Vienna and Dresden possess the autographs of others. Hasse’s instrumentation is certainly not above the low level attained by the average musicians of his time, and his ensembles do not present any features of interest. In dramatic fire also he was wanting, but he had a fund of gentle and genuine melody, and by this fact his enormous popularity during his life must be accounted for. The two airs which Farinelli had to repeat every day for ten years to the melancholy king of Spain, Philip V., were both from Hasse’s works. Of Faustina Hasse it will be sufficient to add that she was, according to the unanimous verdict of the critics (including Dr Burney), one of the greatest singers of a time rich in vocal artists. The year of her death is not exactly known. Most probably it shortly preceded that of her husband.

HASSELQUIST, FREDERIK (1722-1752), Swedish traveller and naturalist, was born at Törnevalla, East Gothland, on the 3rd of January 1722. On account of the frequently expressed regrets of Linnaeus, under whom he studied at Upsala, at the lack of information regarding the natural history of Palestine, Hasselquist resolved to undertake a journey to that country, and a sufficient subscription having been obtained to defray expenses, he reached Smyrna towards the end of 1749. He visited parts of Asia Minor, Egypt, Cyprus and Palestine, making large natural history collections, but his constitution, naturally weak, gave way under the fatigues of travel, and he died near Smyrna on the 9th of February 1752 on his way home. His collections reached home in safety, and five years after his death his notes were published by Linnaeus under the title Resa till Heliga Landet förättad från år 1749 till 1752, which was translated into French and German in 1762 and into English in 1766.

HASSELT, ANDRÉ HENRI CONSTANT VAN (1806-1874), Belgian poet, was born at Maastricht, in Limburg, on the 5th of January 1806. He was educated in his native town, and at the university of Liége. In 1833 he left Maastricht, then blockaded by the Belgian forces, and made his way to Brussels, where he became a naturalized Belgian, and was attached to the Bibliothèque de Bourgogne. In 1843 be entered the education department, and eventually became an inspector of normal schools. His native language was Dutch, and as a French poet André van Hasselt had to overcome the difficulties of writing in a foreign language. He had published a Chant hellénique in honour of Canaris in the columns of La Sentinelle des Pays-Bas as early as 1826, and other poems followed. His first volume of verse, Primevères (1834), shows markedly the influence of Victor Hugo, which had been strengthened by a visit to Paris in 1830. His relations with Hugo became intimate in 1851-1852, when the poet was an exile in Brussels. In 1839 he became editor of the Renaissance, a paper founded to encourage the fine arts. His chief work, the epic of the Quatre Incarnations du Christ, was published in 1867. In the same volume were printed his Études rythmiques, a series of metrical experiments designed to show that the French language could be adapted to every kind of musical rhythm. With the same end in view he executed translations of many German songs, and wrote new French libretti for the best-known operas of Mozart, Weber and others. Hasselt died at Saint Josse ten Noode, a suburb of Brussels, on the 1st of December 1874.

A selection from his works (10 vols., Brussels, 1876-1877) was edited by MM. Charles Hen and Louis Alvin. He wrote many books for children, chiefly under the pseudonym of Alfred Avelines; and studies on historical and literary subjects. The books written in collaboration with Charles Hen are signed Charles André. A bibliography of his writings is appended to the notice by Louis Alvin in the Biographie nat. de Belgique, vol. vii. Van Hasselt’s fame has continued to increase since his death. A series of tributes to his memory are printed in the Poésies choisies (1901), edited by M. Georges Barral for the Collection des poètes français de l’étranger. This book contains a biographical and critical study by Jules Guillaume, and some valuable notes on the poet’s theories of rhythm.

HASSELT, the capital of the Belgian province of Limburg. Pop. (1904), 16,179. It derives its name from Hazel-bosch (hazel wood). It stands at the junction of several important roads and railways from Maaseyck, Maastricht and Liége. It has many breweries and distilleries, and the spirit known by its name, which is a coarse gin, has a certain reputation throughout Belgium. On the 6th of August 1831 the Dutch troops obtained here their chief success over the Belgian nationalists during the War of Independence. Hasselt is best known for its great septennial fête held on the day of Assumption, August 15th. The curious part of this fête, which is held in honour of the Virgin under the name of Virga Jesse, is the conversion of the town for the day into the semblance of a forest. Fir trees and branches from the neighbouring forest are collected and planted in front of the houses, so that for a few hours Hasselt has the appearance of being restored to its primitive condition as a wood. The figure of the giant who is supposed to have once held the Hazel-bosch under his terror is paraded on this occasion as the “lounge man.” Originally this celebration was held annually, but in the 18th century it was restricted to once in seven years. There was a celebration in 1905.

HASSENPFLUG, HANS DANIEL LUDWIG FRIEDRICH (1794-1862), German statesman, was born at Hanau in Hesse on the 26th of February 1794. He studied law at Göttingen, graduated in 1816, and took his seat as Assessor in the judicial chamber of the board of government (Regierungskollegium) at Cassel, of which his father Johann Hassenpflug was also a member. In 1821 he was nominated by the new elector, William II., Justizrat (councillor of justice); in 1832 he became Ministerialrat and reporter (Referent) to the ministry of Hesse-Cassel, and in May of the same year was appointed successively minister of justice and of the interior. It was from this moment that he became conspicuous in the constitutional struggles of Germany.

The reactionary system introduced by the elector William I. had broken down before the revolutionary movements of 1830, and in 1831 Hesse had received a constitution. This development was welcome neither to the elector nor to the other German governments, and Hassenpflug deliberately set to work to reverse it. In doing so he gave the lie to his own early promise; for he had been a conspicuous member of the revolutionary Burschenschaft at Göttingen, and had taken part as a volunteer in the War of Liberation. Into the causes of the change it is unnecessary to inquire; Hassenpflug by training and tradition was a strait-laced official; he was also a first-rate lawyer; and his naturally arbitrary temper had from the first displayed itself in an attitude of overbearing independence towards his colleagues and even towards the elector. To such a man constitutional restrictions were intolerable, and from the moment he came into power he set to work to override them, by means of press censorship, legal quibbles, unjustifiable use of the electoral prerogatives, or frank supersession of the legislative rights of the Estates by electoral ordinances. The story of the constitutional deadlock that resulted belongs to the history of Hesse-Cassel and Germany; so far as Hassenpflug himself was concerned, it made him, more even than Metternich, the Mephistopheles of the Reaction to the German people. In Hesse itself he was known as “Hessen’s Hass und Fluch” (Hesse’s hate and curse). In the end, however, his masterful temper became unendurable to the regent (Frederick William); in the summer of 1837 he was suddenly removed from his post as minister of the interior and he thereupon left the elector’s service.

In 1838 he was appointed head of the administration of the little principality of Hohenzollern-Sigmaringen, an office which he exchanged in the following year for that of civil governor of the grand-duchy of Luxemburg. Here, too, his independent character suffered him to remain only a year: he resented having to transact all business with the grand-duke (king of the Netherlands) through a Dutch official at the Hague; he protested against the absorption of the Luxemburg surplus in the Dutch treasury; and, failing to obtain redress, he resigned (1840). From 1841 to 1850 he was in Prussian service, first as a member of the supreme court of justice (Obertribunal) and then (1846) as president of the high court of appeal (Oberappellationsgericht) at Greifswald. In 1850 he was tried for peculation and convicted; and, though this judgment was reversed on appeal, he left the service of Prussia.
