** TJte names of the stocks known only since the fifteenth century 

 are put into italics. If the " Skralings " of the Norse discoverers of 

 America were Esquimaux, Europeans became acquainted with the 

 latter six or seven centuries earlier. 



It is curious to observe that almost all the woolly- 

 headed people are also long-headed ; while among the 

 straight-haired nations broad heads preponderate, and 

 only two stocks, the Esquimaux and the Australians, are 

 exclusively long-headed. 



One of the acutest and most original of ethnologists, 

 Desmoulins, originated the idea, which has subsequently 

 been fully developed by Agassiz, that the distribution 

 of the persistent modifications of man is governed by 

 the same laws as that of other animals, and that both 

 fall into the same great distributional provinces. Thus, 

 Australia ; America, south of Mexico ; the Arctic regions ; 

 Europe, Syria, Arabia, and North Africa, taken together, 

 are each regions eminently characterized by the nature 

 of their animal and vegetable populations, and each, as 

 we have seen, has its peculiar and characteristic form of 

 man. But it may be doubted whether the parallel thus 

 drawn will hold good strictly, and in all cases. The 

 Tasmanian Fauna and Flora are essentially Australian, 

 and the like is true to a less extent of many, if not of
