 that found in the adults of the lower races of Men and in the 

 Apes. 1 The whole embryonic pelvis is comparatively long and 

 narrow ; its angle of inclination is much greater than in the

 meet with a form of sacrum resembling that of lower Mammals, 

 and a promontory which only slightly projects (cf. Fig. 53). 

 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 and narrowness.
