wet cloth, preferably one which has been saturated with the 

 glycerin — gum mixture, to prevent dessication. 



26. Sural artery: Pophteal; by branches to popKteal 

 lymph node and fat and to both heads of the biceps femoris; 

 other branches go to the triceps surae m. (44), one of which 

 (small saphenous a.) continues along the lateral surface of the 

 lateral head of the gastrocnemius and tendon of Achilles to the 

 OS calcis, thence along the lateral and dorsal surface of the foot 

 and fifth digit and probably joins the plantar arch (29). 



27. Anterior tibial a.: Popliteal; to plantaris m. and dor- 

 sum of foot. Passes from the popliteal region craniad between 

 the tibia and fibula, along the interosseous membrane and on the 

 lateral side of the tibia; gives off a branch which passes through 

 the distal end of the interosseous membrane to the plantaris 

 m. (45), thence along the tibia and tendons of the anterior 

 tibial muscle (47), through the transverse crural ligament and 

 onto the dorsum of the foot. Frequently arteries 27 and 28 are 

 not injected. 



28. Peroneal a.: Anterior tibial, craniad of the inter- 

 osseous membrane; to toes. This artery passes along the inter- 

 osseous membrane (visible on lateral side of tibia), gives off a 

 branch which goes through the distal end of the space between 

 the tibia and fibula to the plantaris muscle (45), thence along 

 the tibia and, with the tendons of the anterior tibial muscle, 

 through the transverse crural ligament onto the dorsum of the 

 foot where it anastomoses with the dorsal interosseous branch 

 of the plantar arch. 



29. Plantar arch. The saphenous artery, through its con- 

 tinuation, the posterior tibial, forms the major portion of the 

 plantar arch, although the peroneal a. (cf. 27), anterior tibial 

 (27) or small saphenous (cf. 26), any one, or all three, may 

 contribute to the formation of this arch.
