 trypanosomes iis there wore red Mood corpusejis. 'rii.y were extremely active, and a great 

 variety of forms were seen due to the propagation wliieli was proceeding. Dividing forms, 

 both long and short, were numerous, as were broail forms ami forms united bv tli.ir posterior 

 ends (Fig. 71). 



Some of till' parasites presenteil a very curious aspect, their undulating membranes 

 being of great size. 



Considering the great infeetioii, the gerbil sliowed remarkably little sign of illne.ss. 



Treatiiii^nt with tlie blood serum of a 

 water liurk was begun on Mareh 'JOtli,

 need be here eonsidered.

was enlargeil, its length being lith

 Xotiiing ei.sc of interest was noted. 

 Tile lieart's blood and liver showed 

 degeneration forms of trypauosonies. 



Smears of tlie spleen, brain, spinal 

 cord, bone marrow ami intestines, 

 showed nothing peculiar.

The blood was examined every day with negative results down to March 3Uth. On that 

 day one trypanosome, a long form, was found in the wliole cover glass preparation. The 

 goat presented no sign of illness. Thereafter the blood rcnniined free till April Kith, when 

 two trypanosonies were found in a cover-slip imparation. They seemed to be long forms. 

 At this time the animal showed no signs of emaciation. Nothing was found in the blood 

 examineil on A|)rii 20111. After this date it was noted that tlie animal was beginning to get 

 thinner. Not till .Iiine "JOth was any sign of weakness exhibited. On that date the goat 

 was found lying down. Tln' appetite was fair. No enlarged cervical glands couhi be 

 fletected. Tryjianosomes, as before, were very scarce in tlie peripheral blood. On 

 June 22nd the goat weighed !)-8 kilos; on May :^ 1st, when in extremis, 88 kilos. No 

 parasites in peripheral blood. The animal was extremely emaciated. There was no oilema 

 and no affection of the eyes. Cliloroform was administered, and a post-mortem pnformeil 

 imme(liately, but little of interest was note(|. There was, however, a marked increase of 

 cerebro-spinal fluid which, moreover, was cloudy, and on standing ileposited much .sediment. 

 The brain was cedeniatous. There was no ulceration in the stomach or intestines. The
