¥m, 14.—, X 2000.Part of a mass of Trypanosoma gambiense from the mid-gut. This figure is given in order to try to convey some idea of the enormous proliferationof trypanosomes which takes place in the intestine of Glossina palpalis. Throughout thewhole length of the alimentary canal, from the proventriculus to the proctodseum, thiscondition is frequently seen, and in the living condition presents an extraordinaryspectacle. Looked at through the wall of the intestine the matted masses are seen inactive movement, swaying about and wriggling in every direction. They do not appearto be attached to the wall of the intestine, but move about freely, and when theintestinal wall is burst pour out in countless numbers. The trypanosomes evidentlybelong to the type figured in the preceding sketch, called the normal reproductive type. 520 Col. Sir D. Bruce and others. Development of (Feb. 15,

Figs. 15—24 represent smaller forms which are fairly common and occur throughoutthe intestine and at ail times. The examples given above are taken from the eighth dayto the fifty-third day. They are called by us small developmental forms, since theyresemble the larger in having clear protoplasm and a compact nucleus. Dividing formsare often seen.
