It was possible definitely to establish the fact that Tt least three and probably four species of entamoebae were present. The entamoehae histolytica was found m four cases. iPntamoeha coli was present in a number ot cases. ZtZoeTa tetragena. An entamoeba resembling in all respects the pub- ii<;hPd descriptions of E. tetragena was found m gbme cases. uo^^^ A numbS of preparations stained with polychrome stains and Iron Haema^ toxylin and^xnaterial containing encysted entamoebae, was forwarded to Sflf,; O F Craig Medical Corps, U.
