But a dog, clutched by the neck from the back, can never be a match for two men, gifted with the intelligence and deftness of men, each of them two-handed with four fingers and an opposable thumb to each hand.

The nails, except those of the hind thumbs, are long and claw-shaped like those of squirrels, and the thumbs of the fore extremities, or hands, are not opposable to the other fingers.

And as to the foot, the great toe of the Marmoset is still more insignificant in proportion than that of the Orang--while in the Lemurs it is very large, and as completely thumb-like and opposable as in the Gorilla--but in these animals the second toe is often irregularly modified, and in some species the two principal bones of the tarsus, the 'astragalus' and the 'os calcis', are so immensely elongated as to render the foot, so far, totally unlike that of any other mammal.

The gorilla has massive spines on the cervical vertebrae above the scapula”; and, like the other quadrumana (4-handed animals) has an opposable thumb on the hind foot.

The greatest of these are, that the feet of the anthropoid or man-like apes, as well as those of all monkeys, are formed like hands, with large opposable thumbs fitted to grasp the branches of trees, but unsuitable for erect walking, while the hands have weak, small thumbs, but very long and powerful fingers, forming a hook, rather than a hand, adapted for climbing up trees and suspending the whole weight from horizontal branches.
