Kegarding- the life cyc'le of this ('(XX'idiiim, \vhi('h on general 
grounds I associate with Eimeria sticdac Lixde.maxn, we hâve 
very litlle information, ail onr experiments having been conduct- 
ed in the field. It ma\', however be remarked that these experi¬ 
ments did not indieate a direct tninsmission through grass or 
waler contaminated bv oocvsts. The first sériés ;it Kisiimu, which 
has alrecady been referred to, was repeated on a larger scale on the 
same ground. The results were inconclusive as the Controls did 
not contract a typical clinical attcuck of the disease. Ail exposed 
animais, however, with the exception of those which were kept 
from contact with the infected area (C animais of first sériés) de- 
A’eloped a marked température reaction commencing between the 
I5th and 20th dav after exposure. A similar reaction preceeded 
the other svmptoms in the A and B animais of the first sériés 
which acquired the tvpical disease. After 53 davs the C animais 
were libenited onto the infected land, and manifested the same 
tenrperature reaction commencing on the i6th and i7th davs. No 
explanation can as vet offered for this constant reaction, except 
the hypothesis that an abortive invasion bv coccidia occurred : 
no form of parasite could be demonstrated in the blood or gland 
fluid to account for it. Further experiments are in progress, but 
the importance of the disease to this part of Africa, and its mark¬ 
ed resemblance to Rinderpest, seem t<> warrant the suggestion 
that OLir field observations are not in complété accord with the 
classical transmission experiments of .Smoxm with the same par¬ 
asite in rabbits. 
We bave now positive knowledge that Coccidiosis extends in 
Rritish East Africa up to the Ab^^ssinian and Somaliland bound- 
aries, and it is now prévalent in épidémie form in German Ffast 
Africa, while DfCLOt’X has recorded a case from Tunis. Its prés¬ 
ence shotdd be energeticall\' sought for in some of the outbreaks 
of doubtful Rinderpest in Egvpt and the Sudan, and its exten¬ 
sion Southwards should be carefullv watched bv the interested 
Colonies. There is as vet no positive evidence that Flanc! and 
Buffalo are attacked, but as Fhiropaans and Natives report having 
seen sick and dead in districts where the cattle are affected, we 
are wise to assume that thev mav plav a part in the disséminat¬ 
ion of the disease.
