Bull 18.—Age, two (?) years. Imported from Leopoldville, March, 1904. In 
good condition ; supposed healthy ; lymphatic glands slightly enlarged. Fairly 
numerous trypanosomes seen in blood and prescapular gland juice. 
Inoculations .—Rat (Kxp. 145) inoculated Aug. 15 intraperitoneally with ac.cm. 
of blood from this animal ; did not become infected. 
Monkey (Cercofithecus schmidti) (Exp. 143) received 8c. cm. of blood intra¬ 
peritoneally, August 15, 1904. Trypanosomes appeared in its blood September 22. 
I hey soon disappeared, and were only occasionally seen during 1904. During 1905 
the monkey seemed quite well, and trypanosomes were not seen in its blood, which 
was examined at intervals. On January 1, 1906, it was very ill, weak, dull and 
apathetic. A single degenerated (?) trypanosome was seen in two coverslip 
preparations. Animal died next day ; immediate cause of death was miliary 
tuberculosis. # 
A rabbit (Exp. 1441 received 3 c.cm. of blood intraperitoneally; never became 
infected ; under observation for six months. 
I he herd at Nouvelle Anvers grazes for the most part on cultivated 
land. Big game is not very abundant, but biting flies of several sorts 
(G lossina pit l pal is, Stomoxys and tabanids') are present. 
Romee, September 12th, 1904. One or two animals now present 
have been here since 189;, but the great majority of the cattle 19 have 
been brought here since the end of 1902. Most of them are of Lake 
Kivu stock and came here by way of Nyangwe. A few head came 
from the Nile. Only nine deaths have occurred since March, 1903 ; all 
weie cattle which had arrived in poor condition two or three months 
previously, it therefore appears that this herd does not lose so many 
animals from disease (trypanosomiasis ?) as do those at Eala and 
Nouvelle Anvers. For example none of the calves born here (first 
m l899) have died - We were shown ten animals that had been kept 
apart from the herd of 25 head because of their lack of condition. 
■ x A them (anived at Romee, July, 1904) were examined.* Four
