" 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 1 Life and 

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



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

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

 /fi*) 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."
