22 SYMBIOSIS 



Biologists and Economists have little cause to congratulate 

 themselves on their mutual elevation, and it is scarcely a matter 

 for surprise that there is usually not much love lost between 

 the two. 



I hope that I have to some extent shown how necessary it 

 is that Natural and Political Economy should nevertheless 

 complement each other. There should be ample scope for a 

 chapter of " Bio-Economics " in connection with the theory 

 of evolution ; and this should in turn furnish Political Economy 

 with appropriate data for a more comprehensive treatment 

 of its own essential subject-matter than hitherto possible.
