The nucleus, a long narrow tube tapering at both ends, especially 
:;teriorly, extends from the blepharoplast toward the anterior end. 
The length of the nucleus was almost the same as that of the 
flagellum* 
The measurements of this form are as follows: — 
Length of body, 38 to 50 fi ; width, 10 to 16/1 ; blepharoplast to 
posterior extremity 2’2 to 4-4/11 ; width of nucleus 12 to 2/1 ; length 
of nucleus 19 8 to 29/1 ; flagellum, i/ - 6 to 27/1. 
A change in the form of a “ leaf-like ” trypanosome observed in 
afresh preparation is illustrated in figs. 32, 33, 34. 1 he parasite was 
watched until it had assumed an appearance, always without well- 
marked striations, almost identical with T. mega. A single form of 
this type, probably identical with fig. 33 . was seen in the stained 
preparations.
