VETERINARY SCIENCE AND PRACTICE. 205 



Shall veterinarians continue to vaccinate with cultures of swine ery- 

 sipelas? Kleinpaul (Berlin. Tierarztl. Wchnschr., 1904, No. 16, pp. 803-306). — Some 

 writers on this subject have contended that vaccination with serum and culture of 

 swine erysipelas is no protection against the disease but, on the contrary, contributes 

 t< i its wider distribution. The author states, however, that hog raisers have found such 

 vaccination necessary in order to secure a profit from the hog industry. Attention 

 is called to the very important and reliable results obtained in the control of swine 

 ervsipelas by this method. The disease is not spread by vaccination. The method 

 has only one disadvantage, viz, that the immunity thus produced is of short 

 duration. 



Report on pig disease in the TJmtali district, G. V. S. Jarvis (Rhodesian 

 Agr. Jour., 1 (1904), No. 6, pp. 170, 177). — The disease prevails most extensively 

 durinsr the rainy season. The rate of mortality is high. The symptoms and lesions 

 are described in detail. Sty-fed hogs are seldom affected. Several species of ticks 

 were found on diseased hogs. The affection does not appear to be contagious. 



Sarcoptic mange in hogs, A. Scholl (Ann. Mid. 1V/., 53 (1904), No. 5\ pp. 

 284-290). — The symptoms of hog mange as caused by infestation with Sarcoptes 

 scabit i mis are described and notes are given on the course of the disease, its distri- 

 bution, transmission to other animals and man, and its treatment. 



The leucocytes of horse blood, Bidault (Bui. Soc. Cent. Mai. Vet., SI (1904), 

 No. 10, pp. 315-317). — An elaborate review of this subject, together with personal 

 investigations by the author, is considered to be of great value by the Veterinary 

 Commission of France. 



Horse sickness experiments, A. Theiler (Transvaal Agr . Jour., 2 (1904), No. 7, 

 pp. 332-334). — Recovered animals are immune to the disease. Immunity may also 

 be produced by simultaneous injection subcutaneously of serum and virus. The most 

 certain and effective immunity, however, is produced by simultaneous injection of 

 virus intravenously and serum subcutaneously. The duration of the inoculation is 

 about 12 days. 



Glanders in German East Asia, Schlie (Berlin. Tierarztl. Wchnschr., 1904, No. 

 13, pp. 238, 239). — A description is given of the clinical history and pathological 

 lesions of glanders cases in a horse and a mule. The usual quarantine and disinfection 

 measures were enforced in order to prevent the further spread of the disease among 

 other army horses. 



Hasty diagnosis in the case of horses suspected of glanders, A. Di Girolamo 

 ( Gior. R. Soc. ed Accad. Yet. Ital., 53 (1904), No. 9, pp. 194-200).— It is recommended 

 that all suspected horses be properly quarantined and premises disinfected, after 

 which a reliable diagnosis may be made. 



The antiseptic action of glycerin and methyl violet on the glanders 

 bacillus, G. Angelici (Rec. Med. Vet,., 81 (1904), No. 1, pp. 14-18). —Virulent cul- 

 tures of the glanders bacillus were shaken up in sterile glycerin and left standing at 

 various temperatures. It was found that the virulence was entirely destroyed after an 

 exposure of 4 to 6 days, as determined by inoculation experiments with rabbits and 

 guinea pigs. Methyl violet (5 parts to 1,000) destroyed the virulence of Bacillus 

 malleus and B. pyocyaneus after exposure for 40 to 50 days. 



Dourine and its treatment, E. Marchal (Rec. Med. Vet., 81 (1904), No. 7. pp. 

 231-237).— Continued experiments have corroborated the author's previous work in 

 showing that dourine may be successfully treated with cacodylate of soda. When 

 given by way of the mouth this remedy may be decomposed into somewhat irritant 

 and toxic substances. It is advisable therefore to administer the drug subcuta- 

 neously. The author treated six cases in horses, in which the characteristic symp- 

 toms were present and trypanosomata in the blood, as shown by inoculation of dogs.. 

 Of these 6 horses, 5 made a complete recovery. The author therefore considers the 

 remedy a very satisfactory one for the treatment of dourine.
