 pp. 102-105. 



In examining the microfilariae of cattle, the authors have observed 

 a minute parasite which resembles the sausage-hke stage of Filaria 

 bancrofti as found in the thoracic muscles of Culex fatigans. This 

 parasite is beUeved to be identical with the embryo of Filaria labiato- 

 papillosa.

It has previously been stated that small rodents, such as mice, when 

 inoculated in the peritoneum with Leishmania tropica exhibit a general 

 infection followed by tumours or similar symptoms of local infection. 

 The experiments conducted by the author have, however, given 

 entirely different results and in his experience the local infection has 

 in every case preceded general infection, which was often entirely 

 lacking in mice that were killed within a short time of the inoculation.

Of 94 pigs brought to the Kisantu market that were examuied for 

 trj'panosomes, 38-3 per cent, were found to harbour Trypanosoma 

 congolense. The infection was found to be general throughout the 

 Inkissi valley, the infected animals frequently showing no outward 

 symptoms of disease. While there is no direct correlation between 

 the existence of the human trypanosome and that of the pig, indirectly 

 the keeping of pigs constitutes a serious danger to the inhabitants, 

 the animals afforduig an abundant and favourite food-supply for 

 Glossina and encouraging its increase. The pigs roam freely about 

 the country in search of food, which is often to be found in the most 

 fly-infested spots, and return to the villages bearing flies on their 

 bodies. These include several species, G. palpalis being the most 

 common. Though this shghtly wooded region is chmatically and 

 topographically ideal from the point of view of resistance to sleeping 

 sickness, 758 deaths from this disease occurred in the years 1910-1913. 

 It is probable that a few natives became infected when travelhng in 

 the neighbouring districts and thus the wooded slopes beside the 

 streams, where the pigs wander and G. palpalis are abundant, have 

 become centres of infection.
