SUPPLEMENTAL HISTORY OF MAN. 175 



of Caucasian origin remaining unaffected for ages 

 by the influence of the torrid region to which they 

 had emigrated sufficiently prove. The uniform co- 

 lour of all the parts in the Negro furnish an argu- 

 ment against the effects of climate. We find also, 

 in examining the dark races, that the same people 

 inhabit the most different climates without any cor- 

 responding change of colour. In the countries 

 nearest to the pole, in Europe, Asia, and America, 

 are to be found very dark races of mankind. The 

 Moors and Arabs are born perfectly fair, and con- 

 tinue so unless much exposed. But the Laplanders 

 and Greenlanders, though never subjected to the 

 influence of even a moderate sun, are dark, nay 

 sometimes black. Buffon, to be sure, has main- 

 tained that extreme cold will produce the same 

 effect as extreme heat in darkening the skin. But 

 if so, we should observe some approximation to this 

 dark colour in the inhabitants of such climates as 

 approach in intensity of cold to the arctic regions. 

 But the reverse is the fact. Climate will no more 

 account for other varieties, than it does for that of 

 colour. The same physical characters, with a very 

 trivial variation, belong to all the natives of Europe, 

 except those of German and Mongolian origin, to 

 the Western Asiatics and the Northern Africans. 

 Climate cannot cause this similarity of character in 

 nations, spread over fifty degrees of latitude ; nor 

 are food, dress, or any other such causes adequate 

 to its explanation. The Mongolian tribes are scat- 

 tered over an immense tract of the earth, under the
