trypanosome concerned {T. peconim) apparently being transmitted at 

 Matiri by Haetnatopota and other Tabanids which were very numerous 

 there during the rainy season. A microscopic examination of the 

 municipal oxen is now made weekly. The most serious veterinary 

 problem to be faced is that of the losses from trypanosomiasis among 

 cattle that become infected in areas where no tsetse occur ; such losses 

 have in past years been very heavy in Buganda, and are the greatest 

 obstacle to the development of cattle transport in the Buganda and 

 Western Provinces. The primary source of infection is in the Glossina 

 areas. Cattle becoming infected there and subsequently brought into 

 contact with healthy herds in fly-free areas have caused extremely 

 heavy losses both among native herds and transport oxen. Many 

 such outbreaks have occurred in areas in which no tsetse have 

 ever been found and in which the other domesticated animals do 

 not become infected. It would appear that Tabanus spp. are the 

 most probable carriers where they are present in any numbers ; in 

 some outbreaks Stomoxys and possibly Haematopota appear to have 

 been the transmitting agents. It is hoped that as the tsetse areas 

 become better known and more accurately defined it will be possible, 

 by the control of stock routes, to avoid the passage of cattle through 

 fly areas and thus to bring about a very material reduction in the 

 danger of infection from this source. 



An Ordinance passed in November controls the movement of 

 animals through tsetse-fly areas and provides for compulsory dipping. 



East Coast fever is endemic throughout the Buganda Province. 

 More work requires to be done in mapping out the non-endemic areas 

 in the Eastern Province and in testing the immunity of cattle from 

 outlying and more recently administered parts of the Province. Money 

 has been sanctioned for the construction of a cattle dip in Kampala, 

 where the grazing is very heavily tick-infested, and it is hoped that 

 when the regular dipping of cattle has been established, together with 

 the eradication of ticks, a reduction in the number of biting flies that 

 molest the cattle may also be effected by this means. In the Mubendi 

 district a number of water-buck died in November and December 

 owing to unusually heavy infestation by brown ticks. Filaria were 

 found on examination of blood slides obtained from these antelopes. 



Piroplasmosis in dogs was recorded in 37 cases in Kampala. One 

 dog brought from Masindi was found to be infected with Trypanosoma 

 brucei and died. 



James (S. P.). Note recording the Proof that Anopheles macuUpennis 

 is an efficient Host of the benign tertian Malaria Parasite in 

 England. — Jl R.A.M.C., London, xxix, no. 5, November 1917, 

 p. 615. 



In order to ascertain by experiment whether A. macuUpennis is an 

 efiicient host and carrier of the malaria parasite in England, a benign 

 tertian gamete-carrier, who had contracted malaria in England, 

 allowed adult female specimens of A. macuUpennis to feed on him 

 between 30th August and 15th September. Dissections of these 

 mosquitos showed many of them to be largely infected with zygotes. 

 This is the first occasion on which this experiment has been made 

 successfully in England.
