GAME ANIMALS TO DISEASE IN AFRICA

from the blood of a monkey and not from any game animal. 
Secondly, that nearly all the animals shown in the table in 
which trypanosomes have been found are game animals. I 
maintain, however, that this is due not so much to the fact 
that other animals do not harbour trypanosomes as to the 
fact that so much attention has been concentrated upon 
game animals that comparatively few animals other than 
game have been examined. 
After examining the information given in this table it 
is important to turn to the antelope experiments carried out 
by the Sleeping Sickness Commission of the Royal Society 
in Uganda 1908-10, and summarised in 4 Sleeping Sickness 
Bulletin,’ No. 35, p. 98, where further observations on 
these same antelopes made by Fraser and Duke in Uganda 
are recorded ; and it is also important to refer to other 
experiments with wild animals in German East Africa. 
It is only necessary here to mention some of the more 
important conclusions which were arrived at as the result 
of these experiments — 
(i) Water-buck, bush-buck and reed-buck can readily be 
infected with a human strain of the trypano- 
some of sleeping sickness by the bites of infected 
Glossina palpalis (‘ Sleeping Sickness Bulletin/ 
No. 25). 
(ii) Antelope of the water-buck, bush-buck and reed-buck 
species, when infected with the virus of sleeping 
sickness, can transmit the infection to clean 
laboratory- bred Glossina palpalis (‘ Sleeping Sick- 
ness Bulletin/ No. 25). 
(iii) And Glossina palpalis infected in this manner can 
transmit the virus to susceptible animals ( 4 Sleeping 
Sickness Bulletin/ No. 25). 
(iv) No antelope up to the present has been found naturally 
infected with Trypanosoma gambiense ( 4 Sleeping 
Sickness Bulletin/ No. 25). 
Later in 1911 Fraser and Duke in Uganda arrived at the 
following conclusions : — 
(i) Antelope may remain in apparently perfect health
