 the nuclear chromatin into eight distinct masses arranged upon the inside 

 of the nuclear membrane; B, division of the nucleus into eight daughter- 

 nuclei; C, further stage of the same process of division; D, complete division 

 of the amoeba into eight daughter amcebse.

 ridding itself of extraneous matter just prior to encystment; B, division of 

 the nucleus into two daughter-nuclei; C, division of the daughter-nuclei into 

 two nuclei; D, eight nuclear stage of the cyst of Entamceba coli; E, F, and 

 G, various stages in the sporogony of Entamceba coli; II , fully developed 

 cyst of Entamceba coli, containing eight daughter-nuclei; /, the young
