Tlie Operation.—Extend the tarsus and forcibly flex the great toe tomake prominent the tendon of the extensor proprius hallucis; make an inci-sion about three inches inlength along the outerborder of this muscle, com-mencing at the bend of theankle; divide the fasciaand expose the fleshy innerportion of the extensorbrevis digitorum muscle;draw the muscle outward,when the artery and itssatellite veins will appear;separate the artery fromthe veins, and pass theneedle as best suits the con-venience of the operator.

The Fallacy.—The ar-tery may pass outside ofthe line indicating itsproper course. Ligature of the Poste-rior Tibial Artery.—Theposterior tibial artery issometimes ruptured infracture of the tibia. The Anatomical Points.—The posterior tibial is anartery of considerable size which comes from the popliteal at the lower border of the popliteus passes obliquely to the tibial side of the leg, there goes downward between.

The linear guide to the vessel is drawn from the middle of the poplitealspace to midway between the inner malleolus and the tuberosity of the oscalcis. This guide is not a feasible one, since to reach the artery by cuttingupon the guide necessitates the division of the fibers of the muscles of thecalf of the leg. The linear guide to the operation is a l
