M. FLEXOR DIGITOEUM BEEVis.-In the dissection of the leg the 

 plantans tendon was found to be flattened where it plays over the 

 summit of the tuber calcanei, and to be attached by slips to the sides 

 of the tuber. From this point the tendon appears to be continued down

the back of the metatarsus ; but there is good ground for supposing 



that the short flexor of the digit has lost its muscular tissue and has 



become continuous with the extremity of the plantaris tendon. The 



long, flattened continuous tendon thus produced comports itself exactly 



as does the metacarpal portion of the superficial flexor tendon of the 



thoracic limb (q.v.). 



M. FLEXOR DIGITORUM PROFUNDUS. — As has been seen, the strong, 



rounded tendon produced by the union of the flexor hallucis longus and 



tibialis posterior immediately proximal to the end of the tibia traverses 



the grooved posterior surface of the calcaneus, where it is bound down 



by a stout ligamentous band, and thence continues down the back of the 



metatarsus. In the proximal third of this region it is ioined by the
