Haemosporidiosis : — 
Invasion of white blood-corpuscles (leucocytes) of a dog by a new 
Hsemosporidian (a “ Leucocytozoon”), around which the leucocyte forms 
a delicate enclosing cytocyst, James (190). 
Karyolytic action of Hcemogregarina magna> and degenerative forms of 
same, Sergent (438). 
Effects of a new “ ffcemamoeba ” on its host (squirrel) * relation to the 
blood-corpuscles, Vassal (495). 
Piroplasmosis : — 
In the case of the curious new Hsematozoan [perhaps an unusual type 
of Piroplasma] from the blood-corpuscles of moles, the parasites may be 
very numerous in the corpuscles, Graham-Smith (163). 
Ring- and bacillary forms of Piroplasma bigeminum in the blood of the 
immune ox, Theiler (479). 
Human piroplasmosis ; relation of the parasites to the red blood- 
corpuscles, Donovan (105). — On naturally occurring piroplasmosis in 
monkeys ( Cercopithecus), Ross (386). — On the frequent presence of Piro- 
plasmata in the blood of cattle in Ireland, and the occurrence of bovine 
piroplasmosis, Mettam (297). — Bacilliform piroplasmosis of cattle in 
Tunis, Ducloux (115). — Equine piroplasmosis, or “biliary fever,” Bow- 
hilTj (37). — Canine piroplasmosis ; abundance, and relation to the blood- 
corpuscles of the parasites in different parts of the body, Graham-Smith 
(162). 
Oriental or Delhi sore ; great resemblance of the parasites to those 
found in Kala-Azar, but the differences between the two diseases are so 
marked that, notwithstanding the almost universal occurrence of the 
parasites (Leishman-Donovan bodies) in the latter type, it is by no means 
certain whether they are really, in this case, the cause of the disease, 
James (191 & 192). 
Manson (298) puts forward the interesting hypothesis that the 
organisms of Kala-Azar and Oriental sore may be identical, but that 
in the latter case the virulence of the parasite has been in some way got 
rid of ; in other words, that these two diseases bear to one another the 
same relation that small-pox (variola) and vaccinia do. 
General account of Kala-Azar and its parasite, Piroplasma donovani , 
Sam bon (398). — Distribution of the parasites of Kala-Azar in the tissues 
(figures given), Statham (466). 
Myxosporidiosis : — 
Schuberg & Schroder (420) did not find any markedly pathological 
effects resulting from the invasion by Myxobolus neurobius of the nervous 
system of the trout. 
Great mortality of fish ( Alosa finta\ due to “pseudodiphtkeria,” caused 
by Branchiophaga n. g., a new Myxosporidian which attacks the branchial 
tissue, Mazzarelli (286 & 287). 
Effects of Microsporidia ( Nosema and Thelohania) on crabs ; atrophy of 
affected musculature, and, in severe cases, interference with breeding 
powers, Perez (342 & 344). — Marked effects of Nosema vayssierei n. sp., on 
tissues of Boetis rhodani (larvse), Hesse (178). 
Sarcosporidiosis:— 
Occurrence of Sarcocystis tenella in sheep (with fatal effects ?) ; presence 
of parasites in fibres of the heart muscle, and of the “ spores ” in the blood, 
Metham (297). 
Other Sporozoa and Disease: — 
Tumorous growths formed in the septum nasi of man by Rhinospori- 
dium n. g., Minchin & Fantham (298).
