CASE ENGLISH, H., aged 19. Patient, who had not been abroad before, left England in 

 October, 1915, for the Peninsula, where he remained two months before being transferred to 

 Egypt. On May 3, 1916, he was found to be a carrier of E. histolytica during the routine 

 examination of cooks in Metras Camp. Patient gave no history of dysentery. There was also 

 an infection of E. coli and E. nana. Patient was observed till May 9 when a 12-day 

 course of emetin was commenced (one-grain injection in the morning and grain in keratin- 

 coated tabloid by the mouth at night). During treatment patient was kept in bed on milk diet. 

 Patient vomited on five occasions after taking the emetin, but notwithstanding this the 

 E. histolytica as well as the E. coli and E. nana infections disappeared, and the only infection 

 to recur was that of E. nana during a control of over one month, the greater part of which 

 patient spent in the convalescent camp on light duty. The emetin had no appreciable effect 

 on the patient's temperature or pulse-rate.
