218 THE DESCENT OF MAN. Pabt I. 



Dr. Lund, 6 that the human skulls found in the caves of 

 Brazil, entombed with many extinct mammals, belonged 

 to the same type as that now prevailing throughout the 

 American Continent. 



Our naturalist would then perhaps turn to geogra- 

 phical distribution, and he would probably declare that 

 forms differing not only in appearance, but fitted for 

 the hottest and dampest or driest countries, as well as 

 for the arctic regions, must be distinct species. He 

 might appeal to the fact that no one species in the 

 group next to man, namely the Quaclrumana, can resist 

 a low temperature or any considerable change of climate ; 

 and that those species which come nearest to man have 

 never been reared to maturity, even under the temperate 

 climate of Europe. He would be deeply impressed with 

 the fact, first noticed by Agassiz, 7 that the different 

 races of man are distributed over the world in the same 

 zoological provinces, as those inhabited by undoubtedly 

 distinct species and genera of mammals. This is mani- 

 festly the case with the Australian, Mongolian, and 

 Negro races of man ; in a less well-marked manner with 

 the Hottentots ; but plainly with the Papuans and 

 Malays, who are separated, as Mr. Wallace has shewn, 

 by nearly the same line which divides the great Malayan 

 and Australian zoological provinces. The aborigines 

 of America range throughout the Continent ; and this 

 at first appears opposed to the above rule, for most of 

 the productions of the Southern and Northern halves 

 differ widely ; yet some few living forms, as the 



but Messrs. Nott and Gliddon (ibid. p. 146, fig. 53) describe him as 

 " a hybrid, but not of negro intermixture."

 They give also corroborative evidence ; but C. Vogt thinks that the 

 subject requires further investigation.
