No attack in Virchow's Munich address surprised me 

 so much, and none so plainly betrayed the subversion 

 of his most important scientific views, as that which 

 he directed against my'observations on psychology and 

 cellular physiology. A mystic dualism in his funda-

 sharpest contrast to the mechanical monism formerly 

 upheld by the famous pathologist of Wiirzburg. 



In my Munich discourse (p. 1 2), I had alluded to

 cell-theory to the general province of theoretic medi- 

 cine ;" and as a logical amplification of that idea, I 

 asserted emphatically that we must ascribe an inde- 

 pendent soul-life to every individual organic cell. 

 "This conception is validly proved by the study of
