as in the higher races of Men. This feature is not, however, 
marked during foetal life, when the form of the pelvis recalls 
that found in the adults of the lower races of Men and in the 
Apes.t The whole embryonic pelvis is comparatively long and 
narrow; its angle of inclination is much greater than in the

adult, and the long axis of the symphysis pubis forms anteriorly 
with the axial line of the body a very acute angle. We herein 
meet with a form of sacrum resembling that of lower Mammals, 
and a promontory which only slightly projects (cf. Fig. 43). 
As a consequence, the entrance to the pelvis is also like that of 
the lower Mammals, and differs greatly from that of the later 
adult form. 
1 The pelvis of the Veddah, according to the Sarasins, differs from that of the 
European in its relative length aud narrowness.
