Fig. 27. Trypanosome shewing trace of axial filament anterior to the tropho-nucleus. 
(Std. Aznr.) 
Fig. 28. Parasite shewing well-developed axial filament with both anterior and posterior 
grannies, the latter in relation with the kineto-vacuole. 
Fig. 29. Trypanosome, 1 hr. after treatment, shewing enlargement of the kineto-vacuole, 
and extrusion of granules from the tropho-nucleus. 
Fig. 30. Large tri-nuclear form shewing two well-marked axial filaments one of wliich 
seems to be dividing. 
Fig. 31. Trypanosome shewing various stages in the division of the granules, also 
dividing kineto-nucleus. 
Fig. 32. Trypanosome, 2 hrs. after treatment, shewing the presence of large chromatoid 
masses in the anterior part of the cell. 
Fig. 33. Trypanosome, 2 hrs. after treatment, shewing a row of granules arranged along 
the degenerating axial filament. 
Fig. 34. Drawn from same slide as the preceding figure; shewing the presence of 
granules in the anterior part of the parasite. 
Fig. 35. Stumpy form, 3 hrs. after treatment, shewing extrusion of granules from the 
tropho-nucleus which are passing forward and crowding in the anterior part of 
the cell. 
Fig. 36. Stumpy form, 3 hrs. after treatment, in which all the granules have crowded to 
the anterior extremity of the cell. 
Fig. 37. Dividing form, 2 hrs. after treatment, in which there is evidence of two axial 
filaments in the two longitudinal rows of granules in the anterior part of the cell. 
Fig. 38. Similar form to the preceding one. 
Fig. 39. Dividing form with two tropho-nuelei, each with a well-marked row of granules 
extending to the anterior extremity. 
Figs. 40—45. Trypanosomes 4 hrs. after treatment ^yith arsenophenylglycin. 
Fig. 40. Small form shewing enlargement of the kineto-vacuole, and presence of small 
granules in the cytoplasm. 
Fig. 41. Advanced stage of degeneration in which the granules have almost disappeared, 
being dissolved in the cytoplasm. 
Figs. 42—43. Stumpy forms containing numerous granules in both the anterior and 
posterior regions of the cell. 
Fig. 44. Trypanosome in which the tropho-nucleus has disintegrated and disappeared. 
The axial filament is faintly shewn. 
Fig. 45. Last stage of degeneration in which the nucleus has become free and the rest of 
the cell fragmented.
