Flexor breri.i minimi <li,<ji,ti. 



Was a small muscle and corresponded to the third plantar inter- 

 osseous. It was inserted into the outer side of base of first phalanx. 



(>/>/>onens minimi digiti. 



This muscle, though poorly developed, was fairly well differ- 

 entiated. 



Interosaei. 



There were seven interossei, of which four were dorsal and three 

 plantar. The basal line of abduction and adduction was the middle 

 toe and not the second metatarsal as in the foot of man. Champneys 

 found the same condition, but in Hepburn's case the basal line was as 

 in man, the second metatarsal. Regarding the shifting of the basal 

 line of abduction and adduction from the middle toe to the second 

 metatarsal Hepburn observes that " so long as the foot remained 

 distinctly a grasping organ the arrangement of its basal line for ab- 

 duction and adduction harmonised with that of the hand, but when 

 the sole of the foot becomes more and more applied to the ground, 

 and the organ is utilised for support and progression, its basal line 

 moves inwards so as to become associated with the second digit, at 

 which the freedom of movement is maintained after the third digit has 

 become applied more directly to the ground ". 



MUSCLES OF ABDOMINAL WALL. 



Regarding the muscles of the abdominal wall it may be noted 

 that the external oblique, internal oblique and transversalis are all 

 well-developed muscles. In the rectus abdominis four inscriptiones 

 tendineui were observed. The posterior wall of the rectus sheath 

 was formed by the transversalis aponeurosis only, and the anterior 

 by the aponeurosis of the external and internal oblique muscles. 

 There was no pyramidalis. The cremaster consisted of several well- 

 developed muscular bundles arising in connection with the lower fibres 

 of the internal oblique.
