arising from the tuberosity of the ischium in common with the com- 

 bined tendon of long head of biceps and semi-membranosus is much 

 thicker. The fibres from the aponeurosis are inserted into the fascia 

 lata mingling with those of tensor vagina; femoris. The rest is in- 

 serted into the linea aspera extending down to within 1 inches 

 of the knee joint. From the lowest fibres a septum extends 

 right down to the external condyle (remains of the septum 

 cruris). The portion of the muscle arising from the tuberosity of 

 ischium may be the representative of an agitator caudse. 



Glutens medius. 



The largest and thickest of the glutei. It arose from the fossa 

 ilii below the crest and extending as far down as the upper margin of 

 the sacro-sciatic notch. It also arose from the fibrous aponeurosis 

 covering it externally. It was a single muscle with a tendon 1 inch 

 in breadth and inserted into the great trochanter. Its anterior border 

 was attached to the, tensor vagina' femoris. Its insertion also mingles 

 with that of the vastus externus. 



Gluteus minimus. 



This muscle was multifasciculate. Four distinct parts can be 

 differentiated, two superficial and two deep. 



The first portion or most anterior and superficial portion situated 

 between the tensor vagina? femoris and the rest of the gluteus minimus 

 is really to be considered the scansorius muscle. It is of triangular 

 shape and 1 inch broad at origin, tapering to J of an inch at its in- 

 sertion, which is slightly tendinous. Its insertion is into the anterior 

 margin of the great trochanter, close to the lower edge of the tendon 

 of the gluteus minimus. 



The other three portions are perfectly distinct at origin, but join 

 later to form a common tendon (Fig. 1). 



Pyriformis. 



Is ^ an inch broad at its origin but tapers to form a long thin 

 tendon of an inch broad. The muscle is quite separate from the
