FIG. XIV. The muscles of the hind-limb, ventral aspect. 



The superficial muscles are shown on the right side ; the sartorius was reflected, the 

 adductor-longus, adductor-magnus, and gastrocnemius were slightly displaced. On the left 

 side the sartorius was left uninjured ; it and the adductor-magnus were a little displaced 

 and the rectus-internus reflected, in order to render visible the semi-tendinosus. 



FIG. XV. The muscles of the hind-limb, dorsal aspect. 



On the left side, the vastus externus, and on the right the biceps-femoris have been 

 reflected. The semi-membranosus and the head of the gastrocnemius of the right side were 

 displaced. 



FIG. XVI. The deep muscles inserted into the head of the femur. 



Bight side from without. 



The cut ends of the muscles removed are all shown.
