THE COMING OF EVOLUTION . 213 



Now that the conception of evolution has become 

 general property, it is difficult to realize how very 

 limited were the numbers of men who were in a position 

 really to judge of the value of the evidence laid before 

 them, evidence that depended on the detailed examina-

 theory of the Universe. 



And even to some naturalists the new ideas were re- 

 pugnant. Owen, the great anatomist, wrote a strongly

 band of evolutionists " Darwin's bulldog," as he 

 called himself. With magnificent courage, ability, 

 and clearness of exposition, he bore the chief brunt 

 of the attack made from all sides on Darwin's book,
