On the Employment of Volunteers in Trypanosomiasis Research; and on the Element of Control in Experiments with Trypanosomes and Glossinae

The two subjects considered in this paper are of practical importance to those interested in research of the kind carried out at the Human Trypanosomiasis Research Institute, Uganda. Their discussion would seriously encumber a report on experimental work and would distract the reader's attention from the main theme. The subjects are therefore dealt with separately, since they bear on all work, past and present, carried out at the Institute.
