196 ON THE LATE PROF. GARROD's CONTRIBUTIONS 



(2) The glutens primus. In Garrod's earlier papers this muscle is 

 called the " tensor fascice ;" and it is described under that name in the 

 first of the two papers quoted. 



Like the four next muscles, this lies on the upper (or outer) surface of 

 the thigh, and with them may be seen in the annexed figure. It is en- 

 tirely superficial, lying beneath the skin, and not requiring any dissection

or its display. More or less triangular in shape, it arises " from the 

 Ibis, 1881, whole length of the postacetabular ridge," as the ridge separating the 

 P- 11- lateral from the dorsal surface of the postacetabular area of the pelvis 

 may be called, " as well as from the posterior border of the ischium, as 

 far forward as its junction with the pubis." Its fibres converge and be- 

 come blended with those of the extensor femoris, forming with them a 

 broad thin aponeurosis which covers the front of the knee and is inserted 

 into the tibia-head the patella, when present, being developed in it.
