These men contained a large number of animal parasites, and were, for 
the most part, infested with worms of various kinds. In all, seven different 
species of worms were identified from their faeces. The percentage infected 
with Ankylostoma was 42-2 in 83 men examined. The infections with E. 
histolytica gave a fairly low percentage, due no doubt to the comparatively 
clean methods of feeding adopted by the majority of Indians and Chinese. 
Yet against this, we have a high percentage of infection with Trichuris tri- 
chiura, suggesting the faecal contamination of food, 
t Amongst the findings may be mentioned a case of infection with Balan¬ 
tidium coli. The patient, an Indian Christian from Bihar, and belonging to a 
Labour Corps, was admitted to hospital with coryza and a slight temperature. 
He had no diarrhoea, but in accordance with custom his stool was sent up 
with those of the other Indians for the usual examination. It was found to 
contain E. histolytica cysts, Ankylostoma eggs, and Balantidium coli in large 
numbers. The patient, who spoke perfect English, was questioned as to 
whether he had at any time suffered from diarrhoea or dysentery, and answered 
in the negative. He stated that he had always enjoyed perfect health and had 
been employed as a labourer in his own country. He had never had anything 
I to do with pigs. I hymol grs. xl was given for the Ankylostoma infection, and 
during the administration of this drug the Balantidium temporarily dis¬ 
appeared from the stool, to reappear later, when the treatment was over. 
Emetine given for the E. histolytica infection had no effect upon the balantidia. 
The patient was eventually discharged cured of his Ankylostoma infection, but 
with the balantidia as numerous as ever. 
The case just mentioned belonged to a party of sixteen of the Bihar Labour 
Corps. All these men were infected with Ankylostoma in small numbers and 
were eventually discharged negative, after the customary dose of forty grains
