186 THEORETICAL DEDUCTIONS 



Vallery-Radot-Pasteur, and others (1910-1917), on the 

 curative properties of peptones, autogenous sera or heter- 

 ogeneous sera, of heterogeneous bacterial antigens in the 

 treatment of acute, chronic or infectious diseases, have 

 resulted in non-specific sero- or proteosotherapy. 



5. Our researches (1912-1919) on the properties and the 

 action of the organism of the colloidal substances obtained 

 by synthesis, and particularly of arsenobenzenes proved to 

 us that all the phenomena of immunity anaphylaxis and 

 of tachyphylaxis, and the methods of preventive vaccina- 

 tion of vaccinotherapy, of anti-anaphylaxis, of serobacterio- 

 therapy and of proteosotherapy, specific or non-specific 

 derived from such phenomena are caused by reactions 

 which, in principle, are of the same kind. 



6. Our researches in the etiology and nature of chronic 

 diseases, inspired by the whole of the preceding work, have 

 resulted in the application in practice of non-specific but 

 selective bacteriotherapy. 



The application of this last method is based on the follow- 

 ing considerations : 



1. Any congestion of the gastro-intestinal mucous mem- 

 brane may be the cause of the passage into the blood of 

 incompletely digested albumins (bacterial or alimentary) 

 which act as antigens. 



2. Every antigen, heterogeneous to the organism, will 

 cause in this organism a state of immunity and of anaphy- 

 laxis; it will be therefore more or Jess harmful. 



3. Every specific curative or preventive antigen (vaccino- 

 therapy, anti-anaphylaxis) will prevent or cure disease, but 

 will at the same time reinforce the specific condition of 

 immunity-anaphylaxis. 



4. If a certain number of different antigens can give, in a 

 given disease, the same preventive or curative result; if, for 

 example, typhoid fever can be treated with equal success 

 by specific bacteriotherapy or by peptone (Nolf), an attack 

 of asthma or urticaria by the injection of a serum, by an 

 autogenous or heterogeneous bacterial preparation or by 

 peptone; syphilis or trypanosomiasis by atoxyl, arseno- 

 benzene or luargol; these results will be obtained by very
