to the human type, and the large cranial capacity, added to consider-

pared with those of Neanderthal man, the chimpanzee, and the gibbon; all drawn 
to the same scale 
ations on the brain-quantities in nearly allied mammalian genera, all 
this leads me to the conclusion that Pithecanthropus should be con- 
sidered as a member, but a distinct genus, of the family of the Ho- 
minidae. 
The resemblance of the fossil femur to that of man, in 
contrast to the apes, is very marked in the knee joint, 
which was adapted for perfect extension of the leg. 
A discussion of the characters of the femur leads Doctor 
Dubois to remark: 
. . . Pithecanthropus cannot have possessed a human-shaped pelvis, 
but as the femur could to all appearance be extended to a human 
degree, the pelvis may have been comparatively more human than 
that of Hy/obates and chimpanzee. . . With such an unhuman pelvis 
the locomotion of Pithecanthropus cannot have been exclusively, per-
