on shores separated by a broad strait of the 

 sea." i 



And to take but one other instance : In con- 

 cluding his review of the causes of extinction 

 of certain animals in Patagonia, he says, " We 

 see that whole series of animals, which have 

 been created with peculiar kinds of organi- 

 zation, are confined to certain areas ; and we can 

 hardly suppose these structures are only adapta- 

 tions to peculiarities of climate or country ; for 

 otherwise, animals belonging to a distinct type, 

 and introduced by man, would not succeed so 

 admirably even to the extermination of the 

 aborigines. On such grounds it does not seem 

 a necessary conclusion, that the extinction of 

 species, more than their creation, should exclu- 

 sively depend on the nature (altered by physical 

 changes) of their country." 3 In these passages 

 we have not only the assertion of species as are 

 established distinction in animal life, we have 

 also the further assertion that these "distinct 

 species," " with peculiar kinds of organization," 

 are to be attributed to " Creation " as their 

 cause, and not " to peculiarities of climate or 

 country."
