Within the pelvis it dis-tributes branches to thePyriformis, Goccygeus, andLevator ani muscles; somehaemorrhoidal branches,which supply the rectum,and occasionally take theplace of the middle hasmor-rhoidal artery; and vesicalbranches to the base andneck of the bladder, vesi-culae seminales, and pros-tate gland. External to thepelvis it gives off the coccy-geal, inferior gluteal, comesnervi ischiadici, muscular,and articular branches. The coccygeal branch runs inwards, pierces the great sacro-sciatic ligament,and supplies the Gluteus maximus, the integument, and other structures on theback of the coccyx. The inferior gluteal branches, three or four in number, supply the Gluteusmaximus muscle. The comes nervi ischiadici is a long slender vessel, which accompanies the great D D 2

The muscular branches supply the muscles on the back part of the hip, anas-tomosing with the gluteal, internal and external circumflex, and superior per-forating arteries. Some articular branches are distributed to the capsule of the hip-joint.■ The Gluteal Artery is the largest branch of the internal iliac, and appears tobe the continuation of the posterior division of that vessel. It is a short thicktrunk, which passes out of the pelvis above the upper border of the Pyriformismuscle, and immediately divides into a superficial and deep branch. Within thepelvis, it gives oif a few muscular branches to the Iliacus, Pyriformis, and Obtu-rator internus, and just previous to quitting that cavity a nutritious artery, whichenters the ilium. The superficial branch passes beneath the Gluteus maximus, and divides intonum
