multiplication of the T. lewisi of rats goes on chiefly in the peritoneal 
fluid at first, after peritoneal injection, and that subsequently the 
forms pass into the blood—disappearing from the body cavity—J urgens 
( 174) maintains that multiplication is not active in the ccelomic fluid—the 
blood being the best medium for the process—but on the contrary many 
of the parasites remain in the peritoneal fluid the whole time the infection 
lasts. It is noteworthy that in their recent paper on T. brucei, Laveran 
& Mesnil (197) say nothing about multiplication in the ccelomic fluid, the 
parasites passing as quickly as may be into the blood. 
Pathogenic effects of T. theileri n. sp. on cattle ; the parasite appears 
harmless to other animals, horse, dog, rabbit etc., which are immune, 
Bruce (46) and Laveran (188); it causes “Galziekte” (bile disease) in 
the Transvaal, and is occasionally associated with Piroplasma bigeminum 
in the blood, Laveran (190). 
If Trypanosomes in Fishes are at all pathogenic they are so only in a 
very slight degree, Laveran & Mesnil (196 & 199); frequency of Try¬ 
panosomes in sewer-rats at Bordeaux, Buard (48). 
Protozoa and other diseases:—Amcebic-dysentery ; Ebstein (97); 
in East Prussia, Jaeger (164) ; Ucke (396) ; and Goldsmith (140). 
Amoeba dysenteries Losch is the cause of amoebic-dysentery, not A. coli 
Shiga (355). 
Relations between Physarum leucophceum ferox, and various yeasts 
(e.g. Mycoderma cerevisice , Saccharomyces cipicidatiis), causing fermentation 
in fruits. If the Mycetozoan gains the ascendency it devours and dissolves 
up the yeast-cells; if these obtain the upper hand the Mvxamcebse either 
die off, or form protective resting-cysts, Chrzaszcz (63). 
On the cause of Cabbage-Hernia, Plasmodiophora brassicce, Feinberg 
(106 & 112). 
Chitonicium simplex , a new Sporozoan (?) parasite, completely destroys 
the epithelial cells of the mantle cavity of Chitons, which it invades, 
Plate (292). 
An intra-nuclear parasite in Euglena deses, causing caryotrophy 
(“ Caryophyseme”); it is of a bacterial nature, allied to Ascococcws billrothi , 
and designated Caryococcus hypertrophicus , Dangeard (79). 
Balantidium coli , in the gut of man, tends to increase diarrhoea and 
catarrh and prevent recovery, Collmann (69). 
An American case of infection with Lamblia duodenalis , Stiles (384); 
Lamblia intestinalis, fatal to rabbits; the relation of flagellate and encysted 
stages to diarrhoea and constipation, Perroncito (290). 
Chilodon cyprini , n. sp., only attacks carp already unhealthy; it seems 
unable to live either separately or on healthy fish, Moroff (267). 
Increase in toxicity of various sera (of rabbit, guinea-pig, etc.) for 
Paramoecia , after injection of cultures of the Infusorian. Remarkable 
specificity of the antiparamoecic serum, Ledoux-Lebard (210). 
Dalgetty’s (77) ciliated organisms in rhinorrhcea, thought by Lillie 
(in the abstr.) to be only ciliated epithelial cells. 
Occurrence of unicellular organisms, quite distinct from the tissue cells, 
each possessing a doubly-contoured membrane and a “ vesicular ” nucleus, 
in cancers; they are distinguished by Romanowsky’s stain from the 
surrounding cancerous tissue, Feinberg (107).—Hertwig (156) having 
examined Feinberg’s cancer preparations, shewing parasites, believes that 
these are not really distinct organisms, but only “vacuoles” sharply brought 
out by the differential staining. [See also Pappenheim (281) in 11 , f, 2.] 
Coccidian-parasite theory of cancer, Borrel (29). 
Parasitic bodies (Sporozoa?) in the fluid from “lesions claveleuses,” 
Bose (31). 
From the behaviour of various Sporozoa (especially Monocystis) injected 
into various organs of different animals, Bose (32) comes to the conclusion 
1902. [Vol. xxxix.] f 8
