borders respectively of the deep flexor tendon, and behave in the 

 same manner as the volar nerves of the thoracic limb. The oblique 

 anastomotic branch from the medial to the lateral nerve is always 

 smaller than that in the metacarpus, and is frequently absent alto- 

 gether.

posterior tibial, has already been observed to produce a double curve 



on a level with the summit of the tuber calcanei, and the origin 



of the recurrent tibial artery from the convexity of the second curve 



has also been noted. After the formation of the second curve the 



medial tarsal artery proceeds in a distal direction upon the deep 



flexor tendon in company with the plantar nerves. Just before the 



base of the metatarsal bone is reached the vessel divides into the 



medial and lateral plantar arteries (a. plantaris medialis ; a. plantaris 



lateralis). 



Of the two plantar arteries the lateral is the larger, and follows the 



lateral plantar nerve (posterior to the nerve) along the border of the
