FIG. XXIX. Various forms of the amoebic, cystic, and flagellate stages 

 of Paramceba hominis. 1 to 13, various forms of the amoebic stage of 

 Paramosba hominis. Note the well-defined nucleus, the oval or round 

 cytoplasmic body or Nebenkbrper in contact with the nucleus in some of the 

 forms; the granular protoplasm; the differentiation of the ectoplasm and 

 endoplasm; the blunt pseudopodia. At 12 is shown a form containing a 

 red blood-corpuscle; 14, 15, and 16 are examples of the encysted stage, 

 showing the division of the nucleus and cytoplasmic body into the swarm 

 spores; 17, young parasites just after leaving the cyst. Some show a short 

 flagellum, while others do not show the flagellum; 18 and 19 are developing 

 flagellate forms of Paramceba hominis, showing the flagellum, nucleus, and 

 cytoplasmic body; 20, fully developed flagellate forms, one of which is 

 undergoing longitudinal division; 21, flagellate forms just after the disap- 

 pearance of the flagellum, one of which already shows the typical amosbic 

 stage.
