of Glnssina which he had taken in his hedroom. It would appear 

 that human trypanosomiasis has always existed in this part of 

 the Sudan, and the only reason why at the present moment the 

 disease has not made very great progress, lies in the fact that the 

 areas frequented by the fly are not numerous or of any large 

 extent in the neighbourhood of inhabited centres, but they never- 

 theless exist. There is some evidence that the natives of these 

 parts have been obliged frequently to change the site of their 

 villages for reasons clearly connected with the disease. The au- 

 thorities have given the necessary instructions for the clearing of 

 the bush in all places known to harbour the flies, and it is hoped 

 that tliese measures will lead to the stamping out of the disease.

 I'ane en Afrique occidentale. [Piroplasmosis (nuttalliosis) of

There are two piroplasmoses of the Equidae at the Cape, one 

 being due to a parasite for which Eranca has created the genus 

 Nuttallia, and the other caused by a true piroplasm (Piroplasma 

 cahalli, Nuttall). 



Theiler has shown that the disease is transmitted by a tick, 

 Rhipiceplialns everts?. It is common in South Africa and the 

 infection amongst imported horses is almost always acute and 

 often fatal. The native animals on the contrary suffer from a 

 more or less chronic disease which generally ends in immunity, 

 but if the blood of the immune liorses be transferred to a healthy 

 horse the latter will acquire the disease. There is some difference 

 in the character of the disease in the horse, the ass and the mule 

 respectively. The author reports observations upon donkeys made 

 in Senegal and considers that he has abundant satisfactory 

 evidence of the existence of the disease caused by Nuttallia equi 

 in Western Africa.

The author examined 300 bugs from Sicily and Northern Italy. 

 These were starved from 8 to 12 days and then allowed to bite a 

 case of kala-azar. He was able to find only a few Leishmania 

 in six of them. The bugs were killed at various times from half 

 an hour up to 22 days after biting the patient. The author 

 thinks that the few parasites which survived for a short time did 

 so chiefly because of the presence of culture liquid which had 

 been sucked up by the bug and not to favourable conditions 

 existing in the insect, and he is decidedly of opinion that the 

 intestine of the bug is not a suitable place for the propagation of 

 Leishmania infantnm . He has also examined large numbers of
