The following paper deals with the well-known phenomena of the fluctuation in the numbers of trypanosomes present in the blood of an animal infected withT. gambiense , and with the equally familiar question of the polymorphism of the parasites. The relation of these factors to the production of infectedG. palpalis is also discussed, and evidence is brought forward to show that a certain type of trypanosome is responsible for the carrying on of the cycle in the transmitting host. The actual details of the structure of the trypanosomes and the sequence of developmental stages in the fly are not touched upon in this account. They will, I hope, form the subject of a subsequent paper.
