In the investigation here discussed I have employed some of 
the treatments that I believe are stamped with the march of 
progress. After conscientious deliberation of the observations 
gained, both from my limited personal experience and from the 
experiences of other investigators in this field, I am inclined to 
believe that the nonspecific theory with regard to the action of 
vaccine as used in this investigation seems plausible, but that 
the exact details of the mechanism of action of each kind of 
treatment administered is not yet fully understood. However, 
it has been observed that a moderate reaction, following the 
administration of any of the treatments discussed, produced 
beneficial effects.
