12 Col. Sir D. Bruce and others. Trypanosome [July 15, 
The average length of the TZrypanosoma brucei, Uganda, 1909, was 
23°6 microns, the maximum 34 microns, and the minimum 15 microns. The 
measurements of the two strains therefore correspond very closely. 
Tables II and V can be compared in the following chart, which gives the 
curves of the distribution in respect to length of Zrypanosoma brucer, Uganda, 
1909, and Trypanosoma brucer, Zululand, 1894.

From these curves it will be seen that there is a marked resemblance 
between the two strains when represented in this way. 
ANIMALS SUSCEPTIBLE TO TRYPANOSOMA BRUCEL 
Table VI shows the effect of inoculating various animals with Trypanosoma 
brucet, Uganda strain, 1909. 
The number of experiments carried out on the various animals is too small 
for comparative purposes, but sufficient to show that cattle and the smaller 
laboratory animals are susceptible to this trypanosome. 
CULTIVATION OF TRYPANOSOMA BRUCEI, UGANDA STRAIN, 1909. 
No attempt was made in Uganda to cultivate this trypanosome. 
CARRIER OF TRYPANOSOMA BRUCEI. 
No experiments were made in the laboratory at Mpumu with Glossina 
palpalis as a carrier of this trypanosome, and no evidence is to hand as to 
how it is conveyed from sick to healthy animals in the district of Bukedi.
