It is round or oval and contains a nucleolus. In the living condition the nucleus is invisible or is faintly seen, but becomes very evident on the addition of acetic acid, etc. The amoebae break down pretty rapidly outside the body, and examination of the dysenteric stools twenty-four hours after being passed usually fails to detect any of them. It is only on one or two rare occasions that the process of division of the amoebae has been observed and described. By some there have also been described encysted forms. These are of smaller size, about lo to 15 ji., with a well-marked capsule, sometimes showing a double contour and a central protoplasm in which a nucleus may or may not be visible. It is still doubtful, however, whether these.
