After the nerve has been separated from the artery a liga-ture is carried around the vessel from without inward and tied.

In the loTrer third of the leg the artery is more superficial, run-ning parallel with the inner border of the tendo Achillis and beingcovered onlj^ by the deep fascia and the integument. The posteriortibial artery is accompanied by two large venge comites, one on eitherside of it. Between the os calcis and the inner malleolus, and beneath theorigin of the adductor poUicis, the posterior tibial artery divides intoits terminal branches, the internal and external plantar. The in-ternal plantar, the smaller, runs along the inne
