THE PHENOMENA OF ORGANIC iVATURE. 157 



Development/' of Von Baer. I believe that if you 

 strip it of its theoretical part it still remains one of the 

 greatest encyclopaedias of biological doctrine that any 

 one man ever brought forth ; and I believe that, if 

 you take it as the embodiment of a hypothesis, it is 

 destined to be the guide of biological and psychological 

 speculation for the next three or four generations. 



THE END.
