    a facet of tlie tuberosity Mglier up than the com- bined origin of the two other hamstring muscles,, and passing down in front of them. Still more in- ternal than the ischial tuberosity, the great sacro- sciatic ligament, with the coccygeal branch of the sciatic artery perforating it, is laid bare by removal of the gluteus maximus. The deep branches of the gluteal artery will be seen, coming ofi* from the parent trunk, and passing^ in beneath the gluteus medius ; and they may be- taken as a guide for the separation of that muscle from the gluteus minimus which it conceals. The- gluteus medius is to be separated from the ilium, so- as to show the extent of its origin as far forwards as the position of the body renders convenient; but its most anterior part is to be left to be dissected when the subject is turned. The su])erior and in^ ferioT branches of the gluteal artery will then be ex- posed ; and the superior ghiteal nerve, a branch from the lumbo-sacral cord, will be seen to supply the gluteus medius and minimus muscles, and to send a branch further forward than can at present be traced, which will afterwards be followed into the tensor vaginae femoris. The gluteus minimus should be detached from the ilium in the same manner aa the gluteus medius, to show the extent of its origin. In contact with the femoral attachment of the quadratus femoris is the upper border of the ad- ductor magnus muscle, which ought to be dissected out. The nerve to the quadratus femoris will be found descending from the sacral plexus, beneath the ob- turator internus and gemelli; and, above the quad-
