Two guinea-pigs (Exp. 148, 152I inoculated in the same way, one from one of 
the above rats, the other from the cow, showed parasites in twelve and fifteen 
days and died in 18 and 23 days of ruptured spleens (much enlarged and friable), 
in one case after slight violence. 
A rabbit (Exp. 147), weight 51b., became infected in nine days. Parasites 
were at first numerous ; they then became scanty and were only seen from time to 
time until January, 1905. None were seen after this. Death from pneumonia 
October 21, 1905. Spleen not enlarged, firm (5 x *8 X *6 cm.), capsule thickened. 
None of glands much enlarged. Animal very fat. 
Monkey [Cercofithecus ?> (Exp. 146), weight S « 3 lb. Inoculated September 13, 
1904, with blood from one of the rats ; showed trypanosomes in its blood three and 
six days later and never again. Death from pneumonia December 16, 1905. 
Spleen slightly enlarged | 5x ix i*scm.), firm ; glands not enlarged ; animal fat. 
The herd grazes on high, wooded, cultivated grounds. Small

Lokandu, October 2 1st, 1904. Sixteen head of cattle present. 
In January, 1902, there were 23; since then 13 have been sent away 
(nineto Romee) and three have died. In only 7 two of the deaths wire 
symptoms resembling trypanosomiasis present. 
We examined eight heads; five had trypanosomiasis. Ihret, all 
infected, of those examined were calves born here. All were thin, bad 
dry noses, much-enlarged glands (to 3 by 4 by 10 cm.) and slight 
temperatures (ior5°F.). 
In two of them there were distinct patches of oedema in the loose 
skin of the throat. Five of those examined were adult cows imported 
from Nyangwe or Kasongo. All were in fair condition ; only one had 
enlarged glands. This one, and one other in whom theie was no 
glandular enlargement, had trypanosomiasis. The one with enlarge 
glands had a temperature of io6 ‘8°F. Trypanosomes were seen in 
small numbers in the blood of only three of these five infected anima s. 
They were seen in much larger numbers in the gland juice in eac 1 
case. 
Inoculations .— A guinea-pig (Exp. .S 3 ) was inoculated intraperitoneally on 
October 22, wit J - bl Ll, from one of the calves contamxng^hree 
■ Panosomes to a covcrslip preparation. It was examined careful \ J
