PHYSICAL HISTORY OF MAN. 



Five of the races have the hair straight or flowing ; while in the 

 others it is more or less crisped, and in two of them it may with pro- 

 priety be termed wool. 



Other modes of associating the races may be also mentioned. Mari- 

 time habits, and the part they appear to have taken in colonizing the 

 globe, would lead us to separate the Malay, Negrillo, and Papuan ; or 

 the three island, from the eight continental races. 



Again, looking to their distribution over the surface of the globe : 

 six of the races may be regarded as Asiatic or East Indian, and four 

 as African ; the eleventh (the White race) being in common, or hold- 

 ing geographically an intermediate position. 



The existence of races, it should be observed, is a phenomenon in- 

 dependent of climate. All the physical races that occur in cold re- 

 gions can be traced by continuity to the Tropics ; where, moreover, 

 we find other races in addition. 



By the same evidence of geographical continuity, the population of 

 one hemisphere can be satisfactorily derived from the other ; but a 

 difficulty arises in narrowing the circle. On the one hand, it seems 

 quite impossible to trace the four African races to any part of Asia ; 

 and on the other, it will be equally difficult to connect the Mon- 

 golian race with the African continent.
