126 THE PROTEOMORPHIC THEORY AND THE NEW MEDICINE 



duplicated everywhere in the hands of the profession at large. 

 The "entirely new field of therapeutics" covering the domain of 

 "all protein infections" is no longer an unexplored territory. 

 Proteal therapy is by way of assuming its predicted rank along- 

 side serum therapy and vaccine therapy, and the suggestion that 

 it may ultimately "altogether outstrip both these relatively new 

 additions to the equipment of the practical physician" seems no 

 longer hazardous. 



If, then, making prophecy possible is the final test of the truth 

 of a theory, the Proteomorphic theory and its corollary, the 

 principle of the Protein Response in Therapeutics, have found 

 abundant justification. I think I am speaking well within bounds 

 in saying that there are few instances in the entire history of 

 medicine in which a therapeutic method has had so secure 

 and so thoroughly scientific a theoretical foundation. In recog- 

 nition of this fact, it would perhaps be permissible to speak of 

 the use of non-toxic (non-specific) proteins as antigens in dealing 

 with all foreign protein invasions and inherent disturbances of 

 protein metabolism, as utilizing and representing the "Pro- 

 teomorphic Principle." 



The particular application of this principle, which will chiefly 

 claim attention in the succeeding chapter the only application, 

 indeed, which has been tested on an extensive scale up to the 

 present time has to do with the vegetable proteins, for which 

 I have suggested, provisionally, the name of Proteals.
