allied though distinct species do not differ nearly so much 

 from each other as do the adults, so it is with the children 

 of the different races of man. Some have even maintained 

 that race differences cannot be detected in the infantile 

 skull." In regard to color, the newborn negro child is red- 

 dish nut-brown, which soon becomes slaty gray; the black 

 color being fully developed within a year in the Soudan, 

 but not until three years in Egypt. The eyes of the negro 

 are at first blue, and the hair chestnut brown rather than 

 black, being curled only at the ends. The children of the 

 Australians immediately after birth are yellowish brown, 

 and become dark at a later age. Those of the Guaranys 

 of Paraguay are whitish yellow, but they acquire in the 

 coiu'se of a few weeks the yellowish brown tint of their 

 parents. Similar observations have been made in other 

 parts of America.' 



I have specified the foregoing differences between the 

 male and female sex in mankind, because they are curi- 

 ously like those of the Quadrumana. With these animals 

 the female is mature at an earlier age than the male; at 

 least this is certainly the case in the Cebus azaroe.'' The 

 males of most species are larger and stronger than the 

 females, of which fact the gorilla affords a well-known 

 instance. Even in so trifling a character as the greater 

 prominence of the superciliary ridge, the males of certain 

 monkeys differ from the females,' and agree in this respect 

 with mankind. In the gorilla and certain other monkeys, 

 the cranium of the adult male presents a strongly marked
