CASE McQuADE, aged 36. Patient, who had previous foreign service in South and West 

 Africa, where he suffered from malaria, left England on September 16, 1915, for the Peninsula. 

 He was there four months and was then transferred to Egypt, where, on March 23, 1916, he 

 was found to be a carrier of E. histolytica during the routine examination of men in Mustapha 

 Camp. Patient says he never suffered from dysentery at any time. He was kept under 

 observation till March 28, when a course of emetin injections of one grain a day for 12 days 

 was commenced. The E. histolytica infection disappeared after the second dose, and during 

 the course a tetramitus infection appeared. During treatment patient was not kept in bed 

 and was given chicken diet. Ten days after the course was finished patient went to the 

 convalescent camp and a fortnight later was again passing cysts of E. histolytica. He was 

 taken into hospital again and on April 5 another course of emetin was commenced. This 

 time he was given each day for 12 days a one-grain injection of emetin in the morning and 

 \ grain of emetin in keratin-coated tabloid at night. He was kept in bed on milk diet. The 

 cysts of E. histolytica disappeared after the first day and did not recur in a control of one month, 

 the last three weeks of which patient spent in the convalescent camp. The emetin by the 

 mouth produced no vomiting and there was no change in the temperature or pulse-rate.
