12 THE QUESTION OF THE RELATION OF 
Sickness Bulletin/ No. 31, p. 410) that 4 such trypanosome 
carriers as this bull have been found in many parts of tropical 
Africa. They are probably at least as dangerous as reservoirs 
of infection as are wild animals.’ 
On the eastern coast -lands of Lake Tanganyika in German 
East Africa Professor Dr. Kleine received a report that cattle, 
sheep, and goats had a trypanosome in their blood, but were in 
health. 
On investigation he found trypanosomes, but the cattle 
in which they were found are said to have looked ill. Cattle, 
goats, sheep, dogs, monkeys, and a pig were inoculated ; only 
the cattle and goats became infected (‘ Sleeping Sickness 
Bulletin/ No. 21, pp. 867-8). 
Later, however, Fischer and Fehlandt found trypanosomes 
in ten out of thirty goats. Goats, sheep, calves, dogs, and 
monkeys were inoculated ; only the goats and sheep became 
infected. The illness is very chronic. Kleine thinks this 
trypanosome is pathogenic for cattle, and proposes to call it 
Trypanosoma caprce (‘ Sleeping Sickness Bulletin/ No. 21, 
p. 868). 
Later, in ‘ Sleeping Sickness Bulletin/ No. 29, p. 822, further 
investigations by Otto Fehlandt are reported from the same 
locality. He found a well-characterised trypanosome in sheep 
and goats, which was pathogenic only for these two species. 
Cattle, dogs, guinea-pigs, and monkeys failed to become in- 
fected when inoculated with the blood of infected sheep or 
goats. This is the trypanosome named T. caprce by Professor 
Kleine (‘ Sleeping Sickness Bulletin/ No. 21, p. 868). 
Two other trypanosomes found in goats and sheep by 
Fehlandt were considered to be T. congolense and T. dimorphon 
(‘ Sleeping Sickness Bulletin,’ No. 29, p. 828). 
A paper by Dr. Erich Weissenborn is summarised in £ Sleeping 
Sickness Bulletin,’ No. 29, p. 824. The following conclusions 
were arrived at : — 
(i) In the blood of a pony from the hinterland of Togo 
small trypanosomes with short flagella were found. 
The animal after eighteen months is apparently 
healthy. One is therefore justified in saying that it 
has some degree of resistance to the trypanosome.
