" The want of a practical acquaintance with Natural History 

 leads the author to take an erroneous view of the bearing of his 

 own theories on those of Mr. Darwin." Review of 'Life and 

 Habit,' by Mr. A. R. Wallace, in * Nature? March 27, 1879. 



" Neither lastly would our observer be driven out of hie con- 

 clusion, or from his confidence in its truth, by being told that 

 he knows nothing at all about the matter. He knows enough 

 for his argument ; he knows the utility of the end ; he knows 

 the subserviency and adaptation of the means to the end. 

 These points being known, his ignorance concerning other 

 points, his doubts concerning other points, affect not the cer- 

 tainty of his reasoning. The consciousness of knowing little 

 need not beget a distrust of that which he does know."
