THE PRESENT POSITION OF CELL-THEORY. 241 



might well have been reversed for the adornment of the 

 title pages of some works of the last twenty years. " Theory, 

 reflection, experience," the last named to be fitted in as best 

 it might. 



Since the above passages were first written the great 

 work of Yves Delage has came into my hands. Mine is 

 not the only voice crying out in the great wilderness of 

 theories. This new voice, however, is far greater and 

 more powerful than mine. The reader who may be uncon- 

 vinced by my clumsy argumentation should turn to the 

 pages of Delage. For clear and candid exposition, trenchant 

 criticism, and rigorous exposure of defects of reasoning, 

 they are unsurpassed. Now that this part of my work is 

 ended I feel that it need never have been begun, for all 

 that I have had to say has been said in greater detail and 

 with much greater force by Delage.
