nourished individual, pale and 
anaemic. The neck bore the scars 
of an operation for the removal 
of cervical glands. The lungs and 
the circulatory and digestive sys- 
tems were apparently normal. 
There was marked splenomegaly, 
the lower margin of the spleen 
being traceable 10 centimeters 
below the left costal margin. The 
organ was hard and smooth to 
the touch. 
Microscopic examination of the 
feces revealed an infection with 
Ancylostoma duodenale. The 
urine was normal. Total ery- 
throcyte count was 4,750,000. 
Haemoglobin not estimated. The 
total leucocyte count was 9,200, 
the microscopist reporting “66 
per cent polymorphonuclear neu- 
trophiles, 26 per cent small lym- 
phocytes, and 8 per cent eosino- 
philes.” Examination of the 
blood later in the day by one of 
us (F. G. H.) failed to disclose 
any parasites. There was, how- 
ever, an unusual amount of free 
pigment on the slide. While it is 
our practice to make note of such 
a finding, undue stress is not laid 
on it when the subject is a Fili- 
pino, or a member of another 
dark-skinned race. 
The following morning, just be- 
fore the patient was sent to the 
X-ray room, the blood was exam- 
ined again, and one rather dis- 
torted parasite was found after 
a long search. The spleen was 
then irradiated, the procedure 
being as follows:
