would seem to me to establish a scientific basis for treatment, 
if the facts could be determined. 
ACKNOWLEDGMENT 
I would, indeed, be ungrateful were I to close this paper with- 
out a word of thanks to this patient who faithfully and patiently 
brought me the material that forms the basis of it. Notwith- 
standing he was feeling really ill much of the time and was 
pressed with business in the bargain, he visited my laboratory 
several times for the purpose of furnishing me with fresh 
material. A worker in another branch of science unrelated to 
zoology, he entered into the spirit of the study with interest and 
with as much enthusiasm as it is possible for a man to assume 
when he feels sick and is uncertain as to the outcome of it all. 
He received no treatment other than the assurance that the 
infection would, in time, die out. It was very pleasant to tell 
him on the day of his departure for the United States that his 
infection was dying out and that‘he probably soon would be rid 
of it.
