nourished individual, pale and 

 ansemic. 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 

 faeces 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- 

 trophils, 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 :
