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. 
ACKNOWLEDGMENTS 
To Prof. Ariston Bautista, chief of the department of 
medicine, University of the Philippines, I acknowledge sincerely 
my high obligations for financing this investigation, and placing 
at my disposal all the material available in the department;

their encouragement in this work: to Prof. F. G. Haughwout 
and Dr. Otto Schébl, for their help and suggestion; to my as- 
sociates, Drs. Facundo Esquivel and Trinidad Banuelos, for their 
valuable codperation; to Dr. Jose Hilario, for the preparation 
of the sensitized vaccine; to Dr. Ricardo Fernandez, for the 
translation of the French literature on the subject; and finally 
to the department of pathology whose autopsy records I have 
been permitted to use in this study.
