Note 766 — Chapter VII · (continued 2)

Desaguliers and Hill were the two first writers who gave themselves up to popularizing physical truths. At the beginning of the reign of George I. Desaguliers was ‘the first who read lectures in London on experimental philosophy.’ Southey's Commonplace Book, 3d series, 1850, p. 77. See also Penny Cyclopædia, vol. viii. p. 430; and, on his elementary works, compare Nichols's Lit. Anec. vol. vi. p. 81. As to Hill, he is said to have set the example of publishing popular scientific works in numbers; a plan so well suited to that inquisitive age, that, if we believe Horace Walpole, he ‘earned fifteen guineas a week.’ Letter to Henry Zouch, January 3rd, 1761, in Walpole's Letters, vol. iv. p. 117, edit. 1840.

In the latter half of the eighteenth century, the demand for books on the natural sciences rapidly increased (see, among many other instances which might be quoted, a note in Pulteney's Hist. of Botany, vol. ii. p. 180); and, early in the reign of George III., Priestley began to write popularly on physical subjects. (Memoirs of Priestley, vol. i. pp. 288, 289.) Goldsmith did something in the same direction (Prior's Life of Goldsmith, vol. i. pp. 414, 469, vol. ii. p. 198); and Pennant, whose earliest work appeared in 1766, was ‘the first who treated the natural history of Britain in a popular and interesting style.’ Swainson on the Study of Natural History, p. 50. In the reign of George II., publishers began to encourage elementary works on chemistry. Nichols's Lit. Anec. vol. ix. p. 763.
