The Gorilla generally adopts a squatting position, with its arms folded across its breast. When asleep he lies stretched out at full length on his back or side, with one arm under his head. The Gorilla is very delicate, and rarely lives long in captivity, even in his own land. THE CHIMPANZEES. GENUS ANTHROPOPITHECUS. _Anthropopithecus_, De Blainville, Leçons Orales (1839). _Troglodytes_ (nec V.), Geoffr., Ann. Mus., xix., p. 87 (1812). {188}This genus contains those Apes which stand highest, next to Man, in the animal kingdom. This proximity, however, refers only to his external conformation and his anatomical structure. The Chimpanzees approach very closely to the Gorilla in structure. Indeed the Gorilla was at first placed in the same genus as the Chimpanzee, which was much earlier known to science than its larger cousin, although an excellent description of the Gorilla, under the name of Pongo, was brought to this country by Andrew Battell, an English prisoner of the Portuguese in Angola, early in the seventeenth century, and published in "Purchas his Pilgrimage," in 1613, a story which for the first time referred definitely to the Chimpanzee. The body is heavily built, but shorter and less robust than that of the Gorilla. The crown is depressed, and the supra-orbital ridges, from which rise stiff strong eye-brows, are prominent, but not remarkably so. The eye-lids are wrinkled, and their margins set with eye-lashes. The nose, of which the ridge is shorter than in the Gorilla, is depressed in the middle, flatter at the extremity, and, as in the last-named species, is furrowed longitudinally, its nostrils looking more downward and forwards. The lips are extremely mobile and protrusile, the upper one broad and the lower one retreating from the mouth, and not forming a true human-like chin, though it is more prominent than in the Orang. The cheeks are more wrinkled than in that Ape. The ears are large and projecting from the side of the head, and often carry a lobule. They are strangely like those of Man, and, as Mr. Darwin has remarked, the Chimpanzee never moves or erects its ears, so that they are equally rudimentary, as far as that function is concerned, as in Man. The shoulders and chest are broad, and indicate great strength. Their lower limbs are longer in proportion than in the Orang. {189}The foot, which is anatomically in no respect a hand, is sometimes shorter than the latter, the great-toe is thick, opposable, and thumb-like, the other four toes are united together by a web, the heel is somewhat developed, and the whole of the sole of the foot is applied to the ground when walking. The arms, of which the humeral segment is about equal in length to the fore-arm, are long, but reach only a little below the knee--their span being about a half more than the height of the body. The hands, which are wonderfully human in form, are broad, comparatively short, and less hook-like than in the Orang.
