 animals examined 40 '^ per cent, of mules and 25"9 per cent, of 

 donkeys were found to be infected with T. hrucei; 20 per cent, of 

 the oxen with T. congolense, and 70 per cent, with T . cazalhoiii; 

 58'6 per cent, of the pio's were infected with T. congolense', I'T per

 with T. cazalbouL Of 7 pig-s examined, 5 were infected with 

 T. hrncei and 2 with T. congolense. Two of the oxen and one 

 g'oat were infected at the same time with T. congolense and 

 T. cazalhoui, and one dog was infected with both T. congolense 

 and T. hrucei. These figures seem to show that cattle and similar 

 beasts are able to resist infection by T. hrucei (hrucei pecaucli), 

 which is unfortunately very virulent in Elizabethville. It is 

 interesting' to note that on tlie high plateau to the soutli of 

 Katanga, where 6'. morsitans alone exists, this fly is able to 

 transmit tlie three same types of trypanosomiasis as those which it 

 spreads in the lowei' regions to the north of the province.

Human trypanosomiasis has been reported as endemic at 

 various points in the French Colony of Fpper Senegal and 

 Niger, and especially towards the south and at the centre of a 

 loop described by the river in the district of Koury, where the 

 malady has been so intense that it has been found necessary to 

 remove the station. 



The author had the opportunity of examining two natives 

 brought up at the Agricultural Station of Kaulikoro suffering 

 from the disease and discovered in addition that in the village 

 itself there were a jiumber of cases of sleeping sickness which had 

 not been reported. The distribution of the disease coincides 

 witli belts of G. palpalls. At first an inspection of the area 

 occupied by .the agricultural station and its immediate neigh- 

 bourhood did not reveal any Glossina nor any place suitable for 

 their reproduction, but after some further investigation a small 

 stream about 200 metres from the station and more or less dried 

 up in the dry season and surrounded by brushwood was found to 

 be infested by them. Further small areas within a radius of 

 3 or 4 kilometres were also found to be infested with the fly, and 

 these were particularly dangerous because they lay in the track of 

 persons going to and from the station. The whole length of this 

 stream was found to be swarming with Glossina at almost all 

 seasons of the year. The Director of the station, whose house 

 was only 200 metres from the stream, showed the author a number
