. The comparative anatomy of the domesticated animals. Horses; Veterinary anatomy. US THE BONES. DiPrERENTIAL CHARACTERS IN THE DIGITAL REGION OF OTHER AnIMALS. In the other domesticated animals, the number of complete digits ia as follows:— Carnivora 5 Pig * Ruminants 2 A. Ox, Sheep, Goat.—These animals certainly possess four digits, but only two are per. feet—the midius and annularis—and these articulate with the inferior extremity of the principal metacarpal (Fig. 71). The two others—the index and auricularis—are in a rudimentary con- dition, and are represented by two small bones situated above and behind the metacarpo- phalangeal articulation. In the Ox, Sheep, and Goat, each of the perfect digits comprises (like the single digit of the Horse) three phalanges and three sesamoids. The first phalanx fairly represents the moiety of this phalanx in the Horse. It has no Fig. 77. Fig. 76. «?/. ANTERIOR LIMB OF THE PIO.

This internal face is plane, and the external convex; these characters are repeated in the other two phalanges. It is also remarked in all the phalangeal bdues, that the external articular facet of the extremities is always larger than the internal. Of the two sesamoids, the t-xternal.
