At the same time the Committee resolved to continue the researches 
on trypanosomiasis in Liverpool, which had been started by Drs. Dutton 
and Todd in Senegambia ; Dr. Thomas was appointed to conduct the 
work, and aided by Dr. Linton experiments were immediately commenced, 
a preliminary note of their work being embodied in this report. The two 
groups of observers have throughout worked together, and in order that 
comparable data might be obtained, selected cases of Sleeping Sickness 
were, by permission of the Congo Free State authorities, sent to the 
observers in Liverpool. A later report will be published on these cases. 
As far as the very numerous and detailed observations ot these workers go, 
they shew that the parasite identified with Sleeping Sickness in Uganda 
and the Congo does not differ from that described by Dutton in the 
Gambia. This view is also held by Laveran and Mesnil in France, and 
Bruce in this country. The question of a curative agent has for a 
considerable time engaged the attention of the members of the research, 
and experiments are now in progress to find a remedial agent which would 
have the same effect in trypanosomiasis that quinine has in malaria. A 
variety of drugs have been used with more or less success ; up-to-date, 
arsenic and trypan red, an aniline dye introduced by Ehrlich and Shiga, 
appear to be the most useful ; the parasite disappears for a time from the 
blood, and the life of the animal is prolonged, but with neither of the drugs 
is an absolute cure attained. A combination of the two appears to 
offer better results ; a large number of animals infected with different 
trypanosomes are under treatment. The present report also embodies an 
important note on the Tsetse-flies, by Mr, E. E. Austen, to whom the 
School is much indebted for describing and identifying the Diptera obtained 
during the Expedition. 
Much important work remains to be done ; a further study of the 
disease from a clinical aspect, extended experiments on the transmission of 
trypanosomic diseases by biting flies, and researches on the lines of 
Schaudinn's work, together with therapeutical observations in patients 
and large animals naturally infected with trypanosomes, are urgently needed.
