Flexor accessorius quarti digiti (figs. 15 & 16) arises from a de- 

 pression on the dorsal side of the anterior edge of the astragalo- 

 calcaneum by a slender tendon, which, passing between this bone 

 and the cuboid, then through a deep groove in the latter, becomes 

 muscular in the sole, and is inserted into the tendon of the flexor 

 perforans opposite the distal extremity of the fourth metatarsal bone ; 

 tbis muscle serves to give a straight direction to that tendon, which 

 would otherwise be weakened by having its direction of effort too 

 oblique.

Deep muscles on plantar surface of the foot. Flexor perforans turned back. 



Adductor digitorum pedis (fig. 15) arises from the tibial side of the 

 apophysis of the cuboid for articulation with the fifth digit, by a flat 

 tendon, which gives off three muscular slips, to be inserted on the 

 peroneal side of the base of the first phalanx of the hallux, and of 

 the second and third digits. 



Flexor brevis quarti digiti (fig. 15) arises from the base of the 

 same articular apophysis, on tbe peroneal side and slightly on the 

 dorsal surface, and is inserted into the peroneal side of the base of 

 the first phalanx of the fourth digit. 



Flexor brevis hallucis (fig. 15), smaller than the last, arises from 

 the edge of the tendon of tibialis posticus and the bone beneath, and 

 is inserted into the base of the first phalanx of the hallux. 



Interossei palmares are two in number : one arises from the 

 proximal half of the tibial side of the fourth metatarsal bone, and 

 from the opposite side of the third, and is inserted into the pero- 

 neal side of the heads of the latter and second ; the other arises 

 from the opposite sides of the second and third metatarsals, and
