Following Lambl in 1870, Lewis and Cunningham foimd amoebae in the feces of nearly 20 per cent, of cholera patients studied in India. These amoebse were described by them as large, granular, vacuolated, amoeboid organisms, which mul- tiplied by gemmation. They also found them in patients who were suffering from other diseases and in healthy individuals. These investigators did not consider the parasites of any pathological significance, but interpreted them as stages in the development of flagellates. It was not until 1875 that a really accurate de- scription was given of an amoeba occurring in man. At that time Loesch, of St. Petersburg, had the good fortune to observe a patient suffering from dysentery in whose feces numerous amoeboid organisms were constantly found. The history of this case shows it to have been one of typical amoebic dysentery, several relapses occurring at intervals, during which the amoebse were demonstrated in the feces. The description of the organisms, as given by Loesch, makes it evident that they were pathogenic in nature and it is probable that he actually studied Entamoeba histolytica, the pathogenic species afterward differ- entiated by Schaudinn. To this parasite he gave the name Amoeba colif He was successful in
