Note 184 — Chapter II

Respecting the causes of the trade-winds, see Somerville's Connexion of the Physical Sciences, pp. 136, 137; Leslie's Natural Philosophy, p. 518; Daniell's Meteorological Essays, pp. 44, 102, 476–481; Kaemtz's Meteorology, pp. 37–39; Prout's Bridgewater Treatise, pp. 254–256. The discovery of the true theory is often ascribed to Mr. Daniell; but Hadley was the real discoverer. Note in Prout, p. 257. The monsoons, which popular writers frequently confuse with the trade-winds, are said to be caused by the predominance of land, and by the difference between its temperature and that of the sea: see Kaemtz, pp. 42–45. On what may be called the conversion of the trades into monsoons, according to the laws very recently promulgated by M. Dove, see Report of British Association for 1847 (Transac. of Sections, p. 30) and Report for 1848, p. 94. The monsoons are noticed in Humboldt's Cosmos, vol. ii. p. 485; Asiatic Researches, vol. xviii. part i. p. 261; Thirlwall's History of Greece, vol. vii. pp. 13, 55; Journal of Geograph. Society, vol. ii. p. 90, vol. iv. pp. 8, 9, 148, 149, 169, vol. xi. p. 162, vol. xv. pp. 146–149, vol. xvi. p. 185, vol. xviii. pp. 67, 68, vol. xxiii. p. 112; Low's Sarawak, p. 30.
