    through which it passes to become the popliteal artery. If the limb is semi-flexed at the knee and rotated outwards, a line drawn from the commencement of the vessel to the internal condyle of the femur indicates on the surface of the body the situation and direction of the artery. If pressure outwards is made on this line in the middle of the thigh, the artery will be compressed against the femur. The artery is divided into two parts, the upper half lying in Scarpa's triangle, the lower half in Hunter's canal. 72. Tlie femoral artery in Scarpa's triangle (Plate IX. fig. 1).—This portion of the vessel is superficial, being covered by skin, and the superficial and deep fasciae. It enters the triangle at Poupart's ligament, and leaves it at the apex of the space where the sartorius and adductor longus muscles meet. It is enclosed along with the vein in a distinct sheath, derived from the transversalis and iliac fasciae of the abdomen. The vein lies at first on the same plane as the artery, and to its inner side ; towards the apex of the tri- angle, although still lying to its inner side, it tends to pass to a deeper plane behind the vessel. The long saphenous nerve lies on the front of the sheath at the apex of the space. The vessel lies upon the psoas and pectineus muscles; it gives off, in addition to several cutaneous branches, the deep femoral artery, which generally arises about a couple of inches below Poupart's ligament. The cutaneous branches arise above the origin of the deep femoral. The artery below the origin of the deep femoral is free from branches. 73. This portion of the vessel is generally ligatured at the apex of the space. The limb being semi-flexed at the knee and rotated outwards, the knee resting on a pillow, an incision, the centre of which corresponds to the apex of the triangle, is made in the line of the vessel; the skin, subcutaneous fat, and muscular fascia, are divided ; the inner edge of the sartorius which overlaps the artery is exposed, the muscle is drawn outwards, and the sheath comes into view. This is carefully opened, and the artery is gently separated from its connections to an extent suflicient to
