Gluteus maximus (figs. 8 & 9, G. Mz). An elongated, but 
tolerably wide muscle (which I provisionally distinguish by this 
name) springs from the outside of the lower part of the ilium, and, 
passing downwards, ends in an aponeurosis which invests the knee 
anteriorly, and passes to the upper part of the front of the tibia. 
' Rectus femoris (fig. 8 & 9, R. F). This is very similar in shape 
and size to the preceding. It arises from the pelvis immediately in 
front of the gluteus maximus and of the acetabulum, and, passing 
downwards on the tibial side of the last-named muscle, is inserted by 
aponeurosis into the inner side of the upper part of the tibia. 
Gluteus medius (?) (fig. 9, G. Md). A small muscle invests the 
outer side of the femur, somewhat as a vastus externus. It arises, 
however, from the ilium just above the acetabulum. Passing down- 
wards, covered by the gluteus maximus, it is inserted into the front 
and peroneal side of the shaft of the femur down to near the external 
condyle.

Gluteus minimus (?) (fig. 9, G. 1). This is a still smaller muscle 
than the preceding, and arises from the hinder surface of the ilium 
and immediately opposite the origin of the gluteus medius, being sepa- 
rated from it only by the ilium. Passing downwards it is inserted 
beside the last-named muscle, with which it is intimately connected. 
Ilio-peroneal (figs. 9 & 10, I. P). A muscle which I propose 
thus to designate, and which is very long and slender, arises from 
the ilium immediately beneath and closely connected with the glu- 
teus maximus. It is inserted into the peroneal side of the fibula 
slightly above its middle.
