Observations on the piroplasniosis of cattle in Indo-China. and proof of 

 piroplasmosis among' buffaloes. II. Scheix (.1/(//. Inxt. ra.slcur, 22 (190S), 

 Xo. 12, itp. JOO-J-lOll, fiijH 11, dyin. I). — The author has studied the forms of 

 l)iroi)hisuia fouud iu the blood of cattle in ludo-Chiua. and here preseuts the 

 res ilts of several observations in detail. The bifreininal pear-shaped form was 

 less frequently met with thau the bacillary and ovoid forms. The pear-shaped 

 form only appears at the height of the disease, namely, from the seventh to the 

 tenth day after inoculation. Occasionally animals were met with which only 

 showed the bacillary form. 



In buffaloes examined the OAoid form was more frequently found than the 

 bacillary, while the pear-shaped form w.is not discovered. 



A new microbe pathogenic in cats, Z. Skrzynski {Ann. Iii.st. Pasteur, 22 

 (1908), Xo. S, 1)1). 682-68S; ahs. in Bui. Insit. Pasteur, 6 (1908), No. 20, p. 

 916). — A new microbe that belongs to the Bacillus coli group was isolated from 

 a disease epizootic in cats. 



Investigations of epithelioma contagiosum of fowls, B. Lipschutz (Centbl. 

 Bukt. [etc.], 1 Abt., Orig., -'/G (1908), Xo. 7, pp. <J/)9-622 ; ahs. in Bui. Inst. 

 Pasteur, 6 (1908), Xo. 16, pp. ?}.7, 7'/6).— This is a contribution from the Pas- 

 teur Institute at Paris, in which the author reports microscopical studies, 

 culture and immunization experiments, and investigations made of the influence 

 of substances on the virus. 



The micrococci are stained bj' the methods of LofHer and Giemsa and feebly 

 by Ziehl's stain. A 10 per cent solution of atoxyl did not attenuate the virus 

 in vitro. Exposed to a 1 per cent solution of saponin for 1- hour the virus 

 was not affected, but after 24 hours it appeared attenuated. A 10 per cent 

 solution of sodium taurochlorate destroyed the virulence of the virus (iu a 

 concentrate<l medium) in 2 hours. The virus was not cultivated artificially. 

 It was found present in the internal organs and also within the brain of dis- 

 eased and recovered pigeons. 



Culture in vitro of the fowl plague virus, E. Marciiovx (Compt. Rend. 

 Acad. 8ci. [Paris], 1-',1 (1908), Xo. 6, pp. 357-359; ahs. in Bui. Inst. Pasteur, 6 

 (1908), No. 20, p. 90-'i). — The author has obtained 10 transplantations in which 

 one-fifth of 1 cc. of the virus was sufficiently virulent to kill a fowl in 2 days. 



Spirochetosis of fowls in South Oran. Transmission of this disease by 

 Argas persicus, E. Brumpt and Foley (Conipt. Rend. Sue. Biol. [Paris], 65 

 (1908), Xo. 26, pp. 132-13'i; ahs. in Bui. Inst. Pasteur, 6 (1908), Xo. 21, pp. 

 96.'i, 965). — Experiments are here reported which show the incubation period 

 of spirochetosis of fowls to be about 64 days, and that at Beni-Ounif about 1 

 in every of the Argasids are infected. The spirochtetes transmitted by 

 .1. persicus are identical with the SpiroeJKCta fjullinaruni discovered by Mar- 

 choux and Salimbeni in Brazil. 



The air-sac mite. L. V. Nathan tJoiir. Dept. Af/r. llrs/. Aust., 17 (1908), 

 Xo. 5, pp. ,S53-856, fiff. 1). — The author reports this mite (Cijtodites nudus) as 

 the source of a disease that is "deciniiiting the poultry yards of the gold 

 lields " in western Australia. lie has also observed the disease in birds iu 

 South Australia. 



Epizootic pneumo-pericarditis in the turkey, W. .Towett (Jour. Compar. 

 Path, and Ther., 21 (1908), Xo. .',, pp. 32'i-^30, ]iys. 2: Ayr. Jour. Cape Good 

 Hope, 3't (1909), Xo. 1, pp. .J.^-JJ). — This disease, said to have been first de- 

 scribed by M'Fadyean in England, is reporfcnl by the writer as having occurred 

 in a large flock near Capetown. South Africa. Inocuhitions and post-mortem 

 examinations are reporteil and the causal organism is described. Iu the out-
