diarrhea and distension of the abdomen; his spleen and 

 liver were enlarged and he had edema of the feet. He 

 died on the fourth day after admission. The postmor- 

 tem was made by Captain Symons, I.M.S., and the 

 following notes were recorded : Considerable amount of 

 clear fluid with floating lymph in abdomen; colon ar 

 splenic flexure gangrenous; transverse colon much 

 thickened — almost half an inch in places and ulcerated. 

 containing raised papillae on the mucous surface of a 

 bright red color; descending colon a dark gray color; 

 spleen much enlarged with pigment in patches; liver 

 much enlarged." 



The Piroplasma donovani is found free in the splenic 

 blood and as a cell inclusion in the red corpuscles and 

 macrophages, but more frequently in the leucocytes; 

 in some of the cells it is multiple. (Christophers.)

Lieut, S. R. Christophers, in his exhaustive mono- 

 graph on this parasite, gives a very minute description 

 of its morphology and multiplication by fission. "Tn 

 films stained by Romanowsky's method the bodies are 

 seen with great clearness. They exhibit a remarkable 

 uniformity in size and appearance. The majority are 

 about 2,5 micromillimeters in diameter, but forms may 

 be found which are a little larger, 3 to 3.5 micromil- 

 limeters, or a little smaller. Very occasionally still 

 smaller bodies, 1.5 micromillimeters in diameter, may 

 be encountered. Most of the bodies are approximately 

 circular in outline, but very mam r , especially the larger 

 forms, are irregularly oval and very much resemble a 

 cockle-shell in shape. This, indeed, appears to be the 

 most typical shape, and even in the apparently round 

 forms an approach to this shape can be made out. Oc- 

 casionally specimens are found more elongated and dis- 

 tinctly pear-shaped. . . . Except in very rare small 

 forms which show only a single chromatin mass, the 

 bodies invariably possess two chromatin masses — a large
