SECTION II. 



CASE LINGARD, H., aged 23. Patient, who had not been abroad before, left England 



in September, 1914. He was on the Peninsula for eight months, where he suffered from 



diarrhoea. He never had dysentery. He came to Alexandria, and was found on March 20, 1916, 



to be a carrier of E. histolytica in the course of routine examination of men in Mustapha 



Convalescent Depot. He had large infection of cysts of E. histolytica, E. coli, and lamblia, 



and also I-cysts. He later had trichomonas occasionally. From March 26 he was given emetin 



!by the mouth (one grain a day for 12 days in tine. opii). He vomited on three occasions. He 



; was not kept in bed, and was given chicken diet. There was no alteration in the pulse-rate, 



land the temperature remained normal or slightly subnormal. All the intestinal infections 



; disappeared under the emetin, but the lamblia and trichomonas recurred soon after, and the 



\E. coli later. From April 13 to April 24 the patient was given /3-naphthol 15 grains three times 



a day for 12 days. The trichomonas did not reappear, but the lamblia and E. coli infections 



remained. After the drug was stopped, the lamblia reappeared in as great numbers as at first. 



There was no recurrence of the E. kistolytica or I-cyst infections.
