ation with the flagellum and undulating membrane. Its loca- 

 tion has been used as a diagnostic point in determining species. 



The protoplasm is homogeneous or granular, depending 

 upon the age of the parasite, its environment and, perhaps to 

 a certain degree, upon the species. Few or many fine or 

 coarser granules may be found scattered throughout the 

 protoplasm. 



Multiplication. Voges gives three forms of multiplication, 

 namely, longitudinal, transverse fi.ssion, and segmentation.

 centrosome] m, undulating membrane; f, flagellum. 3-6 trypanosoma 

 in process of division. 7-10 other forms of viultiplication of Tr. 

 Lewisi, 11, flagella not stained. X about 2,000 diameters [after 

 Laveran and Mesnil). 



He did not observe conjugation. The chromatin divides into 

 from 3 to 10 segments, which assume irregular shapes and loca- 

 tions, some of which are often found well up in the flagellum.
