. The comparative anatomy of the domesticated animals. Veterinary anatomy. MUSCLES OF TEE ANTERIOR LIMBS. Fig. 185. The lateral extensor of the phalanges of Ruminants is thicker than in the Horse, and con- stitutes tlie proper extensor of the external digit (Fig. 185, 5). Its terminal tendon (4', 6, 7) comports itself exactly the same as thnt of the proper extensor of the internal digit, and, con- sequently, does not merit special description. We may remark, with Lecoq, that tiiese two muscles separate the digits from each other in extending tliem; they are, therefore, to a certain point, antagonists of the common extensor. The oblique flexor of the metacarpus in the Camel has a very thin ulnar portion, rather aponeurotic tliau muscular. The inferior tendon of that muscle, at its insertion into the pisi- form bone, detaches a baud to the internal border of the carpus. In this animal, the internal flexor is attached to the superior extremity f the internal border of the metacarpus. The perforatus of the Ox and Sheep is composed of two por- tions, the tendons of which unite towards the middle of tlie metacarpal region. The single tendon (Fig. 186,1, 2, 3) which results from this union afterwards divides into two branches, each of which comports itself, in regard to the digits, as the single perforatus tendon does in the Horse, except tliat they receive from the suspensory ligament a fibrous band analogous to that which, in Solipeds, goes to the perforans tendon. This band (Fig. 185, 13) concurs in the formation of the annular ligament through which the latter tendon passes. In the Camel, the muscular portion of tiie perforatus is not present, but is represented by a tendinous band, the arrangement of which is curious. It arises from the common posterior liga- ment of the carpus, and at its origin adheres firmly to the branch of the suspensory ligament of the fetlock which descends from the pisiform bone ; it goes behind the perforans tendon, where it is completely cov
