ratores externus and interims, and gemelli. They present the same 

 attachments and disposition as the corresponding muscles in man. 



The gluteus maximus is a large, broad, and somewhat extensive 

 muscle. It arises from the upper and posterior aspect of the iliac 

 crest, from the sacral aponeurosis which covers the sacro-caudal mus- 

 cles, and from the transverse processes of the third and fourth caudal 

 vertebrae. It is inserted into the posterior aspect of the shaft of the 

 femur, occupying fully its middle three-eighths. Its upper fibres 

 only are tendinous at their insertion. 



The gluteus medius arises from the upper two-thirds of the dorsal 

 surface of the ilium, from the aponeurosis of the gluteus maximus, 

 and also that separating it from the sacro-caudal muscles ; it is more 

 or less continuous with the pyriformis muscle, and inserted along 

 with it into the great trochanter of the femur. 



The gluteus minimus preserves its usual arrangement ; the gemelli 

 and obturator interims muscles seem to be differentiations from it. 



The tensor faseice femoris is a fusiform muscle. It arises from 

 the ilium (below the sartorius) by a pointed tendon ; the muscle is 

 about an inch and a quarter long, and terminates in the fascia of the 

 thigh. 



The capsular ligament of the hip-joint is very strong ; the liga- 

 mentum teres only moderately so. 



The gastrocnemius has a sesamoid bone developed on its outer head ; 

 it presents no decidedly interesting peculiarities. 



The soleus is a single-headed muscle. It arises from the head of 

 the fibula, and from the peroneal intermuscular septum. It is in- 

 serted into the os calcis along with the preceding. 



The plantaris is a very large muscle. It arises from the outer 

 femoral condyle, and is also attached to the sesamoid bone belonging 

 to the outer head of the gastrocnemius. It terminates in a strong 

 tendon which traverses the inner aspect of the os calcis, and, be- 

 coming expanded in the sole of the foot, forms the plantar fascia. 

 It is closely associated in the sole of the foot with the flexor brevis 

 digitorum. 



In the Caracal, Dog, and Paradoxurus this muscle is not so large. 

 In other respects it does not materially differ from that of the Kin- 

 kajou. 



The popliteus muscle is very large and fleshy. The anterior tibial 

 artery passes above its upper instead of below its lower border as in 

 the human subject. Occasionally, however, this peculiar mode of 

 distribution of the artery is met with in man ; I met with one instance 

 of it during the last winter session. 



The abductor minimi digiti is aborted at the sixth metatarsal base, 

 constituting Wood's abductor ossis metatarsi quinti. 



The flexor brevis digitorum pedis is distributed only to the second, 

 third, and fourth digits ; each tendon, prior to its splitting for the 

 passage of the perforans, is joined by a fleshy slip from the accessorius, 

 given off from the latter opposite the point of junction of the long 

 flexors with the accessorius. The perforatus tendon of the fifth 

 digit is derived from a distinct wedge-shaped muscle, which springs
