Note 612 — Chapter VII

This was discovered by Boyle about 1650, and confirmed by Mariotte in 1676. See Whewell's Hist. of the Inductive Sciences, vol. ii. pp. 557, 588; Thomson's Hist. of Chemistry, vol. i. p. 215; Turner's Chemistry, vol. i. pp. 41, 200; Brande's Chemistry, vol. i. p. 363. This law has been empirically verified by the French Institute, and found to hold good for a pressure even of twenty-seven atmospheres. See Challis on the Mathematical Theory of Fluids, in Sixth Report of Brit. Assoc. p. 226; and Herschel's Nat. Philos. p. 231. Although Boyle preceded Mariotte by a quarter of a century, the discovery is rather unfairly called the law of Boyle and Mariotte; while foreign writers, refining on this, frequently omit the name of Boyle altogether, and term it the law of Mariotte! See, for instance, Liebig's Letters on Chemistry, p. 126; Monteil Divers Etats, vol. viii. p. 122; Kaemtz's Meteorology, p. 236; Comte, Philos. Pos. vol. i. pp. 583, 645, vol. ii. pp. 484, 615; Pouillet, Elémens de Physique, vol. i. p. 339, vol. ii. pp. 58, 183.
