Darwin and DeVries 



De Vries has put the finishing touch upon Darwinism and his famous Muta- 

 tion theory is certain to claim a place equal in rank to the Darwinian theory it- 

 self. Everybody who expects to understand current scientific literature must 

 have a knowledge of how species are supposed to originate by mutations and 

 the only book which goes exhaustively into the subject is
