Note 217 — Chapter IV
Reading edition
Isidore Geoffroy St.-Hilaire remarks (‘Hist. Nat. Générale,’ tom. ii. 1859, p. 215-217) on the head of man being covered with long hair; also on the upper surfaces of monkeys and of other mammals being more thickly clothed than the lower surfaces. This has likewise been observed by various authors. Prof. P. Gervais (‘Hist. Nat. des Mammifères,’ tom. i. 1854, p. 28), however, states that in the Gorilla the hair is thinner on the back, where it is partly rubbed off, than on the lower surface.
