PREFACE, By the Translator.

The Author of these Memoirs, who is a Person of an honourable Family in Prussia, and confess'd by all that know him to be a Gentleman of extraordinary Talents, is one that may be truly said to have seen the World; he having not only travell'd twice thro' the principal Parts of Europe, but by his Acquaintance with People of the first Rank, and a diligent Inquiry and nice Inspection into Men and Things, attained to that Knowledge of Both, which is of such Service and Entertainment to Mankind in the general, and so particularly necessary for All who attend to what is doing in high Life.

He has succeeded very happily in the right Narrative Stile; and the French Language, in which he wrote the following Letters, seems to be as natural to him as if it was his Mother-Tongue. But the Thing which has most contributed to the Demand for these Memoirs, is the Multitude of Characters that the Baron has interspers'd, not only of the Deceas'd, but even of Persons that are still living, and distinguish'd by the exalted Spheres in which they move.

That every one of those Characters is equally just, or that every Circumstance relating to them is told with the utmost Exactness, is not to be imagin'd: For supposing the Author to have been ever so circumspect and impartial, how was it possible for him to take the true Likeness of every one, in such a Variety of Personages of both Sexes, and to be perfectly sure of every Particular that he mentions; since he could not be Eye-Witness of every thing, and must be oblig'd for many to Information from other Persons, of whom, 'tis no wonder if some were prejudic'd? But to do the Baron Justice, it must be allow'd, that he no where fails in that Respect and Decorum to Princes which are their due; and that he has not discover'd a predominant Passion for Satire: because where he has painted in the strongest Colours, and represented his Subjects in the most disadvantageous Light, they were such whose Follies or whose Vices were too flagrant and notorious to be either conceal'd or disguis'd: And, considering the Groupe of Courtiers whom he has crouded into his Canvass, the Reader will rather be surpris'd to meet with so few Imperfections in his Characters, and so many excellent Qualities. By this means, his Memoirs have, upon the whole, done Honour to his Understanding, without offending his Conscience, or hurting his Fortune; he being, at this very time, upon a handsome Establishment at the Court of Prussia.

It cannot possibly escape the Observation of the Reader, that the Baron, when he wrote these Letters to his noble Friend, was a profess'd Member of the Church of Rome; but that nevertheless, he was not such a Bigot to its Constitution, nor such a Believer in the Legends of its Writers, or the pretended Miracles of its Saints, as to incur the Character of a blind and furious Zealot; it appearing on the contrary, from several Declarations of his Mind in the following Pages, that he did not want Charity either in his Nature or Principles for those from whom he differ'd in religious Sentiments. Such a Catholic Spirit, assisted by his good Sense, made it, no doubt, much easier for him, after reflecting upon the Fopperies and Impostures which he had seen in that Church during his Travels, to abjure the Romish and to embrace the Protestant Religion, which he did accordingly with great Devotion last Summer, at Berlin; after which, his Prussian Majesty was pleas'd to distinguish him with peculiar Marks of his Favour and Esteem, by declaring him one of the Gentlemen of his Bed-Chamber, and Chief Cup-Bearer of his Court; and he has very lately given him a considerable Prebend.

To the new Edition of his Memoirs, from which the following Sheets are translated, there's not only a great number of material Additions in the Body of the Work, as is observ'd by the Editor of it, Amsterdam, but several new Notes: In this Translation, these Notes are likewise considerably augmented, for the sake of continuing the Thread of the History to the present Time, by the Notice taken of certain remarkable Alterations, or other curious Particulars that have happen'd to the Persons or the Places mentioned, since 1734, when the said Edition was publish'd.

One great Defect for which the foreign Editor has been very much blam'd, was the want of a Table to these Memoirs; which, if not absolutely necessary in a Work of this kind, wherein so many Persons and Facts are mentioned, cannot be necessary for any Book whatsoever that comes from the Press. To supply this Defect, the Translator has added an Alphabetical Index to each of the two Volumes; which Indexes are the more copious, that the Reader might know where to turn in an Instant for some Account of the Characters, Conduct, or Familys of those public Personages, whose Names so often occur in the News-Papers.
