Note 80 — Chapter II

Sir J. Malcolm (History of Persia, vol. ii. p. 380), speaking of the cheapness of vegetables in the East, says, ‘in some parts of Persia fruit has hardly any value.’ Cuvier, in a striking passage (Règne Animal, vol. i. pp. 73, 74), has contrasted vegetable with animal food, and thinks that the former, being so easily obtained, is the more natural. But the truth is that both are equally natural: though when Cuvier wrote scarcely anything was known of the laws which govern the relation between climate and food. On the skill and energy required to obtain food in cold countries, see Wrangel's Polar Expedition, pp. 70, 71, 191, 192; Simpson's Discoveries on the North Coast of America, p. 249; Crantz, History of Greenland, vol. i. pp. 22, 32, 105, 131, 154, 155, vol. ii. pp. 203, 265, 324.
