MR. MIVART AND MR. DARWIN. 289 



varied successfully, intermarrying, are, I think, greater 

 than the reviewer above quoted from would admit. I 

 believe that on the hypothesis that the variations are 

 fortuitous, and certainly on the supposition that they 

 are intelligent, they might be looked for in members of

 " would " happen to what " does " happen, we find 

 that a few white families have nearly driven the 

 Indian from the United States, the Australian natives 

 from Australia, and the Maories from New Zealand. 

 True, these few families have been helped by immi-

 accelerated a result which would otherwise, none the

There is all the difference between a sudden sport, 

 or even a variety introduced from a foreign source, and 

 the gradual, intelligent, and, in the main, steady, growth 

 of a race towards ends always a little, but not much, in 

 advance of what it can at present compass, until it has 

 reached equilibrium with its surroundings. So far as
