The virulence of the fleece of sheep recovered from sheep pox and 

 not washed, 1/. Drti.KUT ami A. CdNii: (/.'(/. 17/. Tinilovsr, ;.-',s' (1903), Xo. r,, j,/,. 

 8o'>-33!)). — On acconnt of tlic iiiarkc<l infccliniisiR'SS of tliis disease tln' author 

 attempted to deteriniuo the pcrind (hiriiij: wliich the virus may retain its virulence 

 in the fieec*^ of recovered sheep. It was found that within 58 days after inoculation 

 or 4ti days after a <jeneralization of the (hsease the pustules had dried up entirely 

 and were covered with l)rown scales. Experiments showed that native sheep which 

 ha<l Iteen vaccinated were not likely to spread contagion aftt'r a lajise of 2 niontlis 

 from the time of inoculation. 



A clinical study of variola in goats, A. Conte {Rev. Gen. MhJ. ViL, 2 {1903), 

 No. 24, pp. 635-639). — Until within recent years this disease has lieen considered as 

 identical with sheep pox.. It has been shown, however, to be a specific disease. 

 Goats are not susceptit)le to sheep pox. Variola in goats terminates with complete 

 recovery in almost all cases. The pustules developed during tlie progress of this 

 disea.S8 furnish a means of distinguishing l)etween it and sheep pox. The disease 

 does not spread as rapidly as sheep jjox or foot-and-mouth disease, with which it 

 might be confused. In preventing the disease it is recommended that attention be 

 given to disinfection of premises and isolation of diseased goats. 



Swine fever, S. Stockman {Tirmsvaal Agr. Jour., 2 {1904), No. 6, pp. 213-219, 

 pi. 1). — The symptoms, etiology, diagnosis, and treatment of this disease are briefly 

 discussed in connection with statistics relating to the prevalence of hog cholera in 

 America. 



Swine fever, W. C. Quinneix {.Tour. Agr. and Ind. South Anslralia, 7 {1903), Xo. .'7, 

 pp. 308-311, figs. 4)- — Brief notes on the symptoms, post-mortem lesions, and means 

 of eradication of this disease. 



Combating swine erysipelas, J. J. Vv'^esteij ( TijdscJir. VeeaHsenijk. Manndhlad, 30 

 {190 j), A'o. 2, pp. 49-63). — Vaccination is said to be the most rapid and effective 

 method for preventing the general and destructive spread of this disease. The author 

 states that the danger from vaccination is so slight as to be largely characterized as 

 imaginary. Vaccination is therefore recommended as a general method for prevent- 

 ing swine erysipelas. 



Swine erysipelas and its treatment, Bertschy {SrJnrelz. Arcli. Tierh., 4-5 {1903), 

 No. 3, ])p. 115-119). — Notes are given on the distribution and occurrence of this 

 disease. In the Canton of Zurich in the year 1902, 2,242 hogs were vaccinated with 

 the following results: In 2,141 animals no symptoms of the disease appeared; among 

 the 101, however, which were already affected with swine erysipelas, 87 re<"Overed 

 while 14 liad to be killed. The expense of the treatment was about 25 cts. per 

 animal. 



The work of sanitary police with regard to swine erysipelas, G. Ferr.\nt 

 {Rer. Vet. TotdoHse, 28 {1903), No. 2, pp. <?.^-57).— Attention is called to the danger 

 of starting an infection from the many hogs which are transported from place to 

 place freely, although suffering from a latent infection of this disease. After a 

 period of 10 days following treatment by an immunizing serum it is believed that 

 animals are not likely to transmit infection. 



The presence of the bacillus of sw^ine erysipelas on the mucus membrane 

 of healthy pigs, C. O. Jensen {Rev. Vet. TovJomte, 28 {1903), No. 9, pp. 533-538).— 

 Tlie l)acillus of this disease varies greatly and different individuals and races of pigs 

 exhibit considerable difference in their susceptibdity to the disease. The author 

 calls attention to the almost normal and very frequent occurrence of this bacillus on 

 the mucus membranes of healthy pigs. 



Vaccination for hog cholera according to the method of Poels, H. Anker 

 {Tijdsrlir. Vmirlsenijk. Maundhlitd, SO {1902), No. 2, pp. 63-80).— The details of this 

 method are briefly described and notes are jiresented on a nnnd)er of experiments 

 which were made in its application. The author concludes from his expernnents
