" The vein which returns the blood of the inferior extremities is divided in the pelvis into two branches, which correspond with the femoral and ischiadic arteries; the one passes through the ischiadic foramen, and the other through the hole upo/i the anterior margin of the pelvis; but the proportion they bear to each other in magnitude is the very reverse of what occurs in the arteries; for the anterior vein is the principal one, whilst the other is not a very considerable vessel, and receives its supply of blood from the muscles at the pos- terior part of the joint. ' Thefemoral vein (a a), immediately without the pelvis, gives branches on both sides, which receive the blood of the extensor and adductor muscles at their superior part: the trunk passes obliquely under the accessory muscle of the flexor digitorum, and over the os femoris, where it liessuperficially; it then winds under the adductor muscles, and gets into the ham (b />), where it receives many muscular branches, and comes into company with the artery and nerve. It here divides into the tibial (c c) and peroneal veins. The first is joined by some branches from the surface of the joint answer- ing to the articular arteries; it also receives the anterior tibial vein which accompanies the artery of the same name. The tibial vein pro- ceeds down the leg along with the artery on the inside of the deep-seated flexors of the heel: it turns over the fore part of the articu- lation of the tibia with the metatarsal bone, in order to get upon the inner side of the me- tatarsus; above the origin of the pollex, it receives a communicating branch from the peroneal vein, and immediately after two branches from the toes: one of them comes from the inside of the inte
