MYOLOGY 89 



Its tendinous origin is also from the plantar process of the 

 calcaneum, and insertion is upon the base of the first 

 phalanx of digit five. 



M. adductor digiti quarti has origin apparently from 

 the entocuneiform and insertion upon the medial sesa- 

 moid of digit four. 



M. adductor digiti secundi lies partly deep to the 

 last, with origin from the ectocuneiform, and insertion onto 

 the lateral sesamoid of digit two. 



Mm. interossei are quite well developed and apparently 

 number eight — two to each of the three middle digits and 

 one internal to each of digits one and five. Origin is from 

 the bases of the metatarsi, and insertion is upon the sesa- 

 moids of their respective digits.
