CASE BLAIR, J., aged 21. Patient, who had been three years in Australia, left there in 

 February, 1915, and came direct to Egypt, whence he was transferred to the Peninsula. He 

 remained there till July, when he was invalided to Egypt for deafness. In February, 1916, 

 while in Cairo he had his first attack of dysentery, for which he went into hospital. He was 

 given no emetin. He returned to duty, but again had dysentery in March, and was then treated 

 with emetin (two injections a day for a week). He had another attack while in convalescent 

 camp. He was again ill with dysentery in Cairo and was given a further 14 injections of 

 emetin, and was a second time sent to Montazah Convalescent Camp at Alexandria, where 

 dysentery again recurred. He was admitted to the Orwa-el- Waska Hospital on June 6, 1916, 

 and was found to be passing stools with blood and mucus containing large numbers of active 

 amoebae with included red blood corpuscles. From June 7 onwards, patient was given a 

 12-day course of methyl emetin sulphate (one grain injection each morning and one grain in 

 keratin-coated tabloid by the mouth at night). This course of methyl emetin produced no 

 vomiting, but had no effect on the infection. Accordingly the injections were stopped and 

 emetin hydrochloride in keratin-coated tabloid (one grain) was given each night for 12 nights 

 instead of the methyl emetin sulphate. Though this change of drug was made without the 

 patient's knowledge, he vomited on the first three nights after taking the drug. The E. histolytica 

 infection disappeared after the fourth day of treatment, but recurred again later when cysts of 

 the amoeba were found for the first time. The etnetin courses had no effect on the patient's 

 temperature or pulse-rate. During treatment he was confined to bed and was on milk diet.
