Further Researches on the Development of Trypanosoma gambiense in Glossina palpalis . ted 63.—:7l gamhiense from salivary glands, 42 days after infected 64, 65 and 66.—T. gamhiense from salivary glands, 44 days after infected 67 and 68.—T. gamhiense from salivary glands, 46 days after infected 69 and 70.—T. gamhiense from salivary glands, 53 days after infected 71 and 72.—T. gamhiense from salivary glands, 56 days after infected feed. Figs. 60—72 represent aberrant forms of Trypanosoma gamhiense seen in the salivaryglands. The first thing to be noted is the fact that the trypanosomes do not appear inthe salivary glands until a late date ; in this case the earliest appearance is 25 days afterthe infected feed. How they reach these glands is up to the present unknown. Inwhat shape they reach the glands is also unknown. Figs. 64, 65, 69 and 71 might be,said to point to some process of segmentation, of which the finished product isrepresented by fig. ^Q. 1911.] Trypanosoma gambiense in Glossina palpalis. 525. X 2000. Fig. 73.—Trypanosoma gamhiense from salivary glands, 34 days after infected feed. Fig. 74.— T. gamhiense from salivary glands, 42 days after infected feed. Fig. 75.—T. gamhiense from salivary glands, 43 days after infected feed. Figs. 76, 77, and 78.—T. gamhiense from salivary glands, 46 days after infected feed. Figs. 79 and 80.—T, gamhiense from salivary glands, 56 days after infected feed. When alluding, generally, in a previous part of this paper to the types of Trypanosomagamhiense found in the salivary glands, it was said that in the salivary glands, and herealone, the trypanosomes are found to revert to the normal type found in the 73—80 illustrate this reversion. By com_paring them with figvS. 1, 2, and 3, whichrepresent normal blood trypanosomes, it will be seen that they are very similar to theshort and stumpy form found in the blood. No such forms have ever
