140 PARASITIC AMGEB.E OF MAN. 



2. Amoebag in which the chromatin is situated 

 partly within the nucleus and partly near it, in the 

 endoplasm. The chromatin appears to have increased 

 in amount and stains more intensely. This form illus- 

 trates the beginning of the distribution of the 

 chromidia to the endoplasm and the degeneration of 

 the nucleus. 



3. Amreba? in which the chromatin is distributed 

 in very faintly stained grains and rods throughout 

 the endoplasm, the remainder of the nucleus having 

 disappeared. 



4. Amosbse in which the chromatin is collected 

 into small clumps situated near or in the ectoplasm. 

 These organisms represent the stage just before 

 sporulation. 



5. Amrebse in which some of the masses of 

 chromatin are arranged within the ectoplasm causing 

 it to project slightly, and in which one or more of 

 the clumps of chromatin, surrounded by a little 

 protoplasm, is partially or entirely separated from 

 the parent organism. In some of these an unstained 

 area will be observed surrounding the spore, indicat- 

 ing the beginning of the formation of the sheath. 



From the description of the various forms which 

 may be observed in stained preparations it is evident 

 that the entire process of reproduction described by 

 Schaudinn can be followed and the observations of 

 numerous investigators have confirmed his results.
