Trypanosomiasis of Camels 
and length of free part of flagellum; in addition, the distance from the pos¬ 
terior end to the blepharoplast; from the latter to the nucleus; and from the 
nucleus to the anterior end. 
(a) Comparison between the dimensions of the Turkestan trypanosome 
and those from Astrakhan and the Ural region. 
The results of the measurements of a number of trypanosomes from 
camels from these three sources are shown in the two following tables, 
Table 2 showing the actual measurements and Table 3 the averages (in 
microns).

From these results it would appear that the Astrakhan camel trypano¬ 
some is the smallest, but the differences between the three forms are so small 
that it is impossible to base any distinction of species on them. 
(b) Comparison between the dimensions of the Bokhara trypanosomes in 
various experimental animals. 
The results of measurements of trypanosomes taken from the blood of 
the following animals are given in microns in the following two tables (4 and 5). 
In every case the animal was infected with the Bokhara strain of camel 
trypanosome.
