XVIII. PROTOZOA. 
erythrocytes, a certain diagnosis of the pernicious parasite, Maurer 
(250). 
Effects on blood-corpuscles of the Lizard, due to Karyolysus lacertarum , 
Marceau (243). 
Piroplasmosis :—in Algeria, Claude & SouLifi (64) and Trabut 
(391); red water in Rhodesia, Gray & Rorertson (145); Nocard & 
Elmy (275) ; Nocard & Motas (276); Robertson (317) ; and, Texas- 
fever compared with human diseases, Sajo (328). 
Clinical characters and pathology of canine piroplasmosis, Nocard & 
Motas (276); and of “ Tristeza,” Lignieres (227). 
Myxosporidiosis :—The “ Pockenkrankeit 55 of carp, Hofer (160) and 
Luhe (241). Henneguya zschokkei, causes superficial swellings or pustules 
in Coregonus sp., Fuhrmann (131). In the intestine of the Plaice John¬ 
stone (172) describes a Sporozoon parasite [a Glugea ], which quite fills 
up the sub-mucosa, in the form of masses of spherical spore-containing 
cysts, simulating an ovary. No trace of the mucosa is left. 
Sarcosporidiosis :— Sarcocystis muris in mice, fatal effects of, Koch 
( 177); the parasites rapidly overrun the entire muscular system, Smith 
(367). 
Trypanosomosis [Note. Of the various names proposed for diseases 
due to Trypanosomes, e.g. trypanosomiasis, trypanosomatosis , and trypano¬ 
somosis, the Rec. chooses the last, proposed by Brumpt (47) as agreeing 
with the nomenclature accorded to other Protozoan diseases]:—Trypano¬ 
somosis in general, Blanchard (24), Theiler (387), and Wasielewski 
(410). 
Distribution of the four chief varieties of trypanosomosis (Nagana, 
Dourine, Surra, and Mai de Caderas), shewn by a sketch map, Laveran 
& Mesnil (207); besides Dourine, caused by T. equiperdum , Buffard 
& Schneider (49) affirm the existence of another trypanosomosis in 
Algeria (probably Nagana or Surra); Surra in German East Africa 
(Togo, Atakpame etc.), Schilling (339) and Stuhlmann (386); Surra 
and allied diseases and Trypanosomes, Salmon & Stiles (329). 
General account of Nagana, occurrence, transmission, pathology, etc., 
and comparison with Surra, Dourine, etc., Laveran & Mesnil (197) ; 
comparative summary of the chief diseases and their parasites, id. (207). 
A variety of trypanosomosis termed locally u aino” (after the fly, allied 
to, if not identical with, Glossina morsitans, which carries the malady) is 
caused in Central Africa by a new sp. of Trypanosoma. Brumpt (47) 
further describes ineffectual therapeutic and serapeutic remedies tried. 
Pathological effects of Trypanosoma brucei (the Nagana parasite) on the 
rat and mouse, and its distribution in the various organs, Bradford & 
Plimmer (40).—Human serum injected into rats or mice suffering from 
the Tse-tse fly disease (Nagana) destroys the parasites. The serum 
further seems to produce a certain degree of immunity, Laveran (189) ; 
further immunisation experiments, Laveran & Mesnil (198) [see ii, b, 2], 
also Schilling (339). 
Tequina n. sp. causes “ Mai de Caderas ” (hip-paraplegia) of horses in 
South America, and is also fatal to dogs, sheep etc., but not cattle, which 
are immune, Voges (403); animals immunized against Nagana are still 
liable to Mai de Caderas, and their serum has much less action on T. 
equinum[=T. equina\ , and vice versa, Laveran & Mesnil (203); more¬ 
over animals resisting Dourine, are not immune to Nagana, Laveran & 
Mesnil (207). 
Clinical characters of human trypanosomosis in Gambia, caused by 
T. gambiense, n. sp. are chronic, irregular fever, wasting, oedema, splenic 
enlargement, etc., Dutton (94a). [For the discoverer of Trypanosomes in 
man, see ii, f, 3.] 
Whereas Laveran & Mesnil (Zool. Rec. 1901, No. 134) think that
