By its deep sur-face with tlie gluteus medius, pyriformis, gemelli, obturator internus,quadratus femoris, sacro-ischiatic foramina, great sacro-ischiatic liga-ment, tuberosity of the ischium, semimembranosus, semitendinosus,biceps, and adductor magnus; the gluteal vessels and nerves, ischiaticvessels and nerves, and internal pudic vessels and nerve. By itsupper border it overlaps the gluteus medius; and by the lower borderforms the lower margin of the nates. The gluteus maximus must, be turned down from its origin, inorder to bring the next muscles into view. The Gluteus Medius is placed in front of, rather than beneath thegluteus maximus; and is covered in by a process of the deep fascia,which is very thick and dense. It arises
