136 THYI'ANOSOMIASIS IN TllK ANOLO-KOYI'TIAN SUDAN 



was notici'il tliat tlicir iiiovciiicnts wt-rc slugf^isli. As it was cviilcnt tlie <log wmiM die 

 (luring tlu' night it was t-lilin-Dfornu'il and an autopsy pi-rfornicil iininciiiatcly. 



The tenijHTat ure recunl from tlic day wht ii trviianosoincs were found in llu' lih)od was 

 as follows : 



l()4-8 ., Uir)-8"., lon-S'., U)3-l°., 10Ur)°., 108-5^., 105°., I(l31l)„ 1U3"., 102-4°, 

 103-8°., 104-3°., 103-6°., 10-2-4°., 102-8°., 103-5°., 1036°., 103°., 103-2°., 1016° F. 



Gorged female tieks {Itltipireplmlus sdii'/nineii.i) were jiri'seiit on tliis dog, and the 

 blood from their stonniehs was examinee! on several occasions, hut trypanosouies were never 

 found. 



Post-mortem. — Very little gelatinous exudation jirescnt, enuiciation extreme. Muscles 

 pale and tialdiy. Kyes exhihited doiiMi' corneal opaeitv. A complete soft cataract was 

 present in the lens of the left eye — a sym[itoni whi( h I think has not hitherto heeu noted, 

 'rime inifortunately did not admit of an examination of the hrain. 



//<<ir/ largi' and flahliy, with pale mu.scnlar tissue. 



Lniiiis blanched, dry and bloodless. 



Sjili'i-ii : length 7;l in. ; marked enlargeineiit of folliilcs. so tjiat thi' surface of the 

 congested, but dry and tirm organ, was rough to the touch, and exhibited numerous small 

 elevations. 



lAfer. — Large, fatty and congested. 



Stomach. — The vessels passing to ami fiom tjie lesser curvature and distributed 

 externally upon the stonnich walls wen^ gri'atly engorged. The organ was full of dark 

 brown very tenacious mucus. The streaks of coffee-coloured mucus owed their hue to 

 altered blood. 



A large ulcer found at the junction of the smooth ;ind rugose; jiortions of the mucous 

 membrane. Its length was :,' inch, its breailth jith iiu h. Edges of ulcer irregular and 

 soft, its surface was covered by a slightly adherent blooil (lot. In additi(Ui to this large 

 erosion seven small liicmoi-rhagic looking ulcers were found scattered about throughout 

 the rugose portion of the mucous membrane. One or two n[ these looked as though they 

 were undei-going a healing process. In no instance were the tinv central holes, mentioned 

 as having been observed in the ulcerated areas of the stomach of an ox, present in this 

 case. 



Smear preparations were made both from the blood (lot covering the surface of the 

 lai-ge ulcer and also from the ulcerated surface after removal of the clot. These were 

 stained by the Leishinan-lionianowsky method, and in both instances large numbers of 

 spirilla were found (Plate XIII., Fig. <•). These spirilla, which were somewhat blunt 

 at the ends, measured from 28 /j to 7-7 /' in hngtli, ami possessed from four to seven short 

 undulations. Nothing like Leishman-])onovan bodies were seen thougli thev were carefullv 

 looked for, but tryj>anosonies of the short form, whidi stained badly ami appeared 

 degenerated, were present in small numbers. No involution forms were observed. 



Iiiti'.'itiiii.t. — They were searched throughout their whole length but no ulceration was 

 detected. 



The stools were dark, lii|uid ainl otlcnsive. \ snieai- was made of them, which, when 

 stained, showed in addition to bacteria, numbers of spirilla. These latter, however, 

 presented an appearance somewhat different from those mentioned above. Their 

 undulations were longer so that they had m)t th(! saw-edge appearance shown in Fig. ', 

 and they were more pointed at the ends. They may have been merely altered forms.
