MUSCLES OF THE HIND-LEG. 



1. The Sartorius is a broad, thin muscle which 

 covers the anterior and internal parts of the thigh. 

 It arises from the anterior ventral margin of the 

 ilium, and is inserted both on the ligament of the 

 patella and the internal tuberosity of the tibia. 

 (Plates II., III., and IV.) 



2. The Tensor Vaginae Femoris is a large muscle 

 which arises from the anterior end of the ilium 

 and the adjacent fascia. It is inserted by a strong 

 fascia, which dips in between the muscles, and ex- 

 tends down to the external condyle of the femur. 

 (Plates II. and IV.) 



3. The Biceps Femoris is a very large muscle, cov- 

 ering the greater part of the external surface of 

 the thigh. It arises from the tuberosity of the 

 ischium, and is inserted by a strong fascia on the 

 outer side of the tibia, for the greater part of its 

 length. (Plate II.) 



4. The Gluteus Maximus is the muscle lying be- 

 tween the biceps femoris and the tensor vaginae 

 femoris. It arises partly from the sacrum and the 

 fascia covering it dorsally, and partly from the 

 first two caudal vertebrae, and is inserted on the 

 great trochanter and shaft of the femur by a sheet 

 of fascia. (Plate II.) 



5. The Tenuissimus is a long and very slender 

 muscle which arises from the caudal vertebrae, be- 

 low the origin of the gluteus maximus. It runs
