no vertebral origin of the semitendinosus, nor did I find the origin 
to be in part by a fleshy slip from the biceps.

This muscle presents little variation. The ‘‘long fusiform slip” 
uniting the two parts, is so closely joined to the ‘ischio-pubio- 
femoral’ part throughout that it may be easily overlooked. - This 
slip arises from the ischium between the origin of the other parts. 
Sartorius; Plate XV, Sart.; Plate XVI, Figs. 6 and 8, Sar 
The sartorius presents a much less extensive insertion than indi- 
cated by Dr. Allen. In no case did I find the insertion extending 
more than an inch below the head of the tibia, that is not more 
than one-fifth the length of that bone, at which point the insertion 
of the gracilis began. 
Gracilis; Plate XV, Grac.; Plate XVI, Figs. 6 and 8, Gr. 
The gracilis is a broad thin muscle covering the posterior half 
of the mesal surface of the thigh. It arises muscularly from the 
whole length of the symphysis pubis, from the descending ramus 
of the pubis and membranously for an inch, in the female half an 
inch, in front of the symphysis. In one of the males there was no 
origin from the descending ramus of the pubis. The insertion is 
coterminous to the insertion of the sartorius and in the same 
plane, it extends to about the middle of the tibia. The upper part 
of the insertion is by a strong direct tendon five-eighths of an inch 
broad, the remainder consists of oblique fibers, from the caudal 
border of this muscle, which overlie the insertion of the semitendi- 
hosus. According to Dr. Allen’s description this muscle must have 
been very different in his specimens. (See p. 135 of his paper.) 
Adductor magnus; Plates XIV and XV, A. M.; Plate XVI, Figs. 1, 3 and 4, 
A. M. 
The adductor magnus was entirely free from the gracilis, instead 
of taking origin in part from the deep surface thereof. The inser- 
tion occupies not only the lower half of the posterior surface of the 
femur, but also a narrow strip extending up to the gluteal ridge. 
Pectineus and Adductor brevis; Plate XV, Pect. and A. Br,; Plate XVI,

These muscles, inseparably united, arise from the ilio-pectineal 
line as stated by Dr. Allen. In all of my specimens, however, the 
pectineus and adductor brevis were inserted, not upon the adduc- 
tor longus but upon the femur, by a well defined line mesa/ to the 
insertion of the adductor longus. This line began at the lesser
