This is a strong muscle which is 

 attached by a long tendon of origin 

 to the hinder extremity of the 

 femur and the ligaments of the 

 knee-joint. The tendon i-uns in a 

 sheath through the joint and pos- 

 teriorly becomes muscular ; the 

 muscle passes downwards on the 

 outer side of the tibio-fibula to be 

 inserted into the malleolus extermis 

 of this bone and into the anterior 

 extremity of the calcaneus. It has 

 an action similar to that of the 

 m. tibialis anticus.

As already mentioned, the ten- 

 don of the m. gasfrocnemins is, at 

 the heel, continued into a strong 

 aponeui'osis, and possesses at this 

 place a thickening ^ The aponeu- 

 rosis is of triangular form, the 

 base directed towards the toes and 

 attached to these. The lateral 

 borders of this triangle are con- 

 tinued into weaker fasciae, which 

 are attached to the two long tarsal 

 bones. The inner border in par-
