    We cannot understand PI. 294, fig. 2. The foreshortening is probably wrong. What are described above as the internal fibres of glutceus maximus, Cuvier and Laurillard call biceps, while the deep inner fibres correspond to their “ biceps—portion femorale.” Mayer assigns to glutceus maximus an insertion into the great trochanter; he speaks further of its tendon as blending with a portion of the “ caput breve des M. occipitis.” Glutceus medius arises from the side of the upper part of the sacrum beneath glutceus maximus, from the upper half of the back of the ilium, from the dense fascia covering the muscle, and from the lower and anterior part of the crest of the ilium as far as the anterior spine. It is separated from glutceus minimus by vessels, and the superior gluteal nerve. Prom this origin the fibres converge and are inserted as follows:—The anterior two- thirds into a line which extends obliquely downwards and for- wards from the superior and posterior part of the great trochanter, the posterior third into the apex of the trochanter and into a ligament which passes thence to the acetabulum. The most posterior fibres pass down to the posterior root of the trochanter about 8 inches from its apex. C. and L.—276-7; 287-8; 294 (a1). Glutceus minimus arises from the middle third of the back of the ilium beneath glutceus medius. The fibres converge to a small tendon which is inserted into a depression on the outer aspect of the root of the trochanter. C. and L.—287-8 (a2); 294, fig. 1 (a2). The / of the last- mentioned figures, “pyramidal (sacro-trochanterien),” we have not found as a separate muscle. In the absence of a2 this would agree with our G. minimus. Biceps femoris arises by a thin round tendon from the tuber- osity of the ischium beneath and external to the other hamstring muscles. It is narrow above, but widens greatly below. The more anterior fibres are continuous with the lower fibres of glutceus maximus, and are inserted into the outer side of the femur for several inches above the knee. A separable strap-like bundle of the most, posterior fibres proceeds from the belly of the biceps to the fascia of the leg. The peroneal nerve separ- ates the anterior from the posterior division of the muscle. C. and L. (biceps—portion femorale).—274-5; 276-7; 287-8;
