At KiRUNDU there were a few miserable-looking trypanosome- 
infected cattle, in the hands of the natives. 
EALA, August, 1904. Before reaching Eala a report was received 
from the Veterinary Surgeon resident there, M. Bertolotti, in which he 
described an obscure disease affecting the cattle under his care. I he 
symptoms resembled those of trypanosomiasis, and on examination 
we succeeded in finding the parasites in one cow (I*ig. 0 in which the 
disease was well advanced (no trypanosomes were found by a single 
centrifugahsation of the blood of five other animals chosen from the 
herd for their lack of condition). Tire extent ol the disease at IE ala is 
shown by the following review of the cattle records. 
There is at present a herd of 43 cattle at Eala. 1 hese represent 
the remnants and product of 51 cattle sent here from the Lower 
Congo in May, 1901, one bull and ten cows (of these only two cows 
are still alive), and from April to May in 1902, five bulls and thirty-five 
cows (of these one bull and 26 cows are still alive). 
The great mortality amongst these animals has been almost 
exclusively due to trypanosomiasis.*' Calves born at Eala (and at 
Eouvelle Anvers) hav e suffered specially from this disease ; of 3b bom 
at Eala only 14 are living (for example, of 15 bull calves born between 
August, 1902, and January, 1904, 12 were dead in August, 1904, of 
trypanosomiasis). Some of the young animals born here which are 
s tdl alive are undersized and obviously ill developed.
