. The comparative anatomy of the domesticated animals. Veterinary anatomy. 294 THE MUSCLES. a third (Fig. 131, 9), wide, flat, and often very voluminous, situated between the preceding and the external obturator; it is attached, by its inner border, to the external border of the ischium, contracting intimate adhesions with the other two and with the tendon of the internal obturator, and becoming inserted by the whole extent of its external border into the digital fossa. Relations.—The gemelli respond posteriorly, to the sciatic nerves; anteriorly, to the capsule of the hip-joint and the external obturator, through the medium of an adipose cushion. Action.—Like the preceding muscle, these rotate the thigh outwards, and perhaps tend to produce the abduction of this ray. nnTEKENTIAL CHAEACTEKS OF THE MUSCLES OF THE THIGH IN OTHEE THAN SOLIPED ANIMALS. A. Anterior Crural Region. In the Ox, Sheep, and Goat, the muscle of the fascia lata is much wider than in Solipeds. In the Dog and Cat, this muscle offers in front a supernumerary fasciculus—• a long thick band, confounded inwardly with tue long abductor of tlie leg, and extending vertically from the external angle of the ilium to the patella, into which it is inserted by a short aponeurosis. The anterior rectus of flic thigh in the Dog and Sheep has only one originating branch. The anterior gracilis, the very email muscular fasciculus, is only present in Solipeds . and Carnivores. B. Posterior Crural Region. Epminants.—In the Ox, Sheep, and Goat, the two portions of the long vastus are but little distinct from each other, and the anterior is reinforced superiorly by the superficial gluteus, which, with the long vastus, forms but one remarkably developed muscle. Fi?. II ill,; "J The internal face of this muscle has no point of attachment on the femur; it glides behind the trochanter by means of a vast mucous bursa, which is often thc- seat of pathological alterations—synovial tumours which constitu
