vi CREATIVE EVOLUTION 



to Mr. H. Wildon Carr, the Honorary Secretary of 

 the Aristotelian Society of London, and the writer of 

 several studies of &quot; Evolution Creatrice.&quot; l We asked 

 him to be kind enough to revise the proofs of our 

 work. He has done much more than revise them : 

 they have come from his hands with his personal 

 mark in many places. We cannot express all that 

 the present work owes to him.
