286 EXPERIMENT STATION RECORD. 



little hope is to be entertained of curing actual cases by serum inoculations. A bib- 

 liography of the subject is added. 



Horse sickness of South. Africa, E. Nocard {Rec. Med. Vet., Paris, S. ser., 8 

 {1901), No 2, pp. 37-51, fig. 1). — The author discusses the serious outbreaks of this 

 disease among horses at the beginning of the South African war. Charts are given 

 showing details of the clinical history of a number of cases. The organism of the 

 disease has not been isolateil, but it is believed by the author to be a protozoan 

 parasite, which is probably transmitted by means of some insect, possibly the 

 mosquito. 



MaUgnaut oedema in the horse, E. Zschokke {Schweiz. Arch. Thierh., 43 {1901), 

 No. 1, pp. 20-24). — In one case the disease developed in consequence of stepping on 

 a nail. The wound was treated with lysol, but 9 days afterward the disease appeared. 

 The symptoms and the course of the disease are described in this and several other 

 cases. 



Sheep pox, E. Perroncito {Gior. R. Soc. Accad. Vet. Itcd., 60 {1901), No. 3, pp. 

 64, 65). — Brief notes on the history and unusual severity of an outbreak of this dis- 

 ease during the past year. The author discusses the methods which have thus far 

 been adopted for preventing the spread of the disease. 



Dourine, J. De Does {Veeartsenijk. Bladen r. Nederl.-Indie, 13 {1900), No. 2, pp. 

 104-164.) — This disease prevailed to an unusual extent during the past season in 

 Soemedang. The author discusses in detail the history of a large number of cases. 

 The pathogenic organism was not isolated. 



Hog-cholera remedy, C. L. Penny {Delaware Sta. Rpt. 1900, pp. 96-98). — An analy- 

 sis was made of a proprietary preparation sold as a " preventive and cure for hog 

 cholera," and the results are compared with a formula recommended by the Bureau 

 of Animal Industry of this Department. It is thought that the compounder meant 

 to follow the formula of the Department and the author questions whether a remedy 

 prepared in this way should be sold under a proprietary name. 



In this connection an examination was made of 41 samples of antimony sulphid 

 sold by retail druggists in Delaware and other States. The results showed that 33 

 samples were entirely free from antimony in any form. 



Rabies: Its cause, frequency, and treatment, D. E. Salmon {U. S. Dept.Agr. 

 Yearbook 1900, pp. 211-246). — A discussion of the cause, nature, distribution, and 

 means of treating this disease, with historical notes on the success which has been 

 obtained along this line in other countries. 



Diseases of poultry, A. G. Gilbert {Canada Expt. Farms Rj)ts. 1900, p. 259). — In 

 cases of outbreaks of infectious diseases the author recommends thorough disinfec- 

 tion of the premises. For the destruction of lice a fluid preparation containing 4 oz. 

 of corrosive subUmate and 4 oz. of common salt was found efficient. These sub- 

 stances should be dissolved in from 2 to 4 qts. of water, and all parts of poultry 

 houses should be thoroughly sprayed. This treatment may be followed by white- 

 washing. 



Asthenia or going-light of fowls, F. D. Chester {Delaware Sta. Rpt. 1900, pp. 

 52-60, fig. 1). — From cases of this disease the author isolated 2 organisms, one of 

 which was the coli bacillus and the other similar to Bacillus vulgaris. Detailed state- 

 ments are given concerning the morphological and cultural characters of the organ- 

 ism, and a table is presented comparing the organism with Bacterium asthenioe, as 

 described by Dawson. 



When fed to young chickens in ordinary food, this organism produced a rapidly 

 fatal disease. Asthenia occurs more frequently in young chickens than in older ones. 

 Apparently the organism is not pathogenic for old fowls, except to a limited extent. 

 It is considered merely a virulent form of the coli bacillus.
