Ruminants.—In the Ox, Sheep, and Goat, the hiceps femoris is but little distinct from tlie posterior portion of the superficial gluteus. It is longer and paler than in the Horse, and its fibres are not penniform as in Solipeds. The semitendinosus has no sacral prolongation: it arises only from the ischium. The semimembranosus is divided, inferiorly, into two branches: one, very thick, passes to the femur; the other, much smaller, termi- nates by a tendon which is insinuated iieueath ''S° 1^^* the internal lateral ligament of the femoro- tibial articulation, to gain the superior ex- tremity of the tibia. In the Camel, an important peculiarity should be noticed. In the posterior crural region is found an elastic apparatus n sem- bling that in the anterior limb of this animal. This is in the form of a thick fascia, whicii descends from the supra-spinous ligament and the aponeurotic sheath of the coccygeal muscles, is attached to the ischial tuberosity, largely covers the space between the biceps femoris and semitendinosus, crosses the sinus of the femoro-tibial angle, and lies on the retaining aponeurosis of the popliteus and lateral extensor of the phalanges. Here it divides into two portions : the smaller is com- posed of fasciculi a little apart, which pass backwards and mix with similar fasciculi from the inner surface of the thigh, and become attached to the tendon of tho gastrocnemius; the larger portion descends
