I n the extensive biological literature on the genus PEasmodium there are relatively few observations on nuclear division. Many of these are of doubtful value because of the preparations used, which were frequently air-dried blood films fixed in methyl alcohol and stained with a Romanowsky stain. Other reports are indefinite, like that of Thomson ( '32) who says : "When about to divide, the karyosome breaks up into numerous minute granules, giving the nucleus a more diffuse appearance, and by a form of mitosis the chromatin divides into two masses, producing a dumbbell appearance. "

Two workers have described mitosis in some detail, but inaccurately. Schaudinn ('02) described mitosis in the assexual forms of P. t~iziux; in the red blood cells of man. His observations are based on blood films prepared in a variety of ways and also on living material.
