ETHNOLOGICAL EELATIONS. 



Distribution and Varietal Distinctions — Question of Species or 

 Varieties — Plurality or Unity of Origin ? — Higher and Lower 

 Varieties — Relations of ttese in time and space — Lowly 

 Origin of tlie Human Eace — Question of Extinct Varieties — 

 Our Third Proposition. 



If then, it be admitted that physical conditions — that 

 is, situation, climate, food, and the like — ^in conjunc- 

 tion with other causes to be afterwards noticed, are 

 instrumental in producing varietal distinctions among 

 animals, to these we must also look for the ethnological 

 differences that prevail among mankind. Admitting 

 that man constitutes the only species of a single genus, 

 there can be no doubt that his species presents several 

 varieties and numerous sub-varieties, down even to 

 minor and more limited distinctions. We say varieties, 

 but it may be fairly questioned whether what are now 

 called varieties would not have been regarded as 

 distinct species, had zoologists had the courage to 

 apply to man the same methods of dififerentiation that 

 they are in the habit of applying to other animals. 

 There is certainly a much wider difference between
