blackleg, rabies, glanders, fout-and-moutli disease, pleuro-pneunionia, sheep 

 pox, sheep scab, swine i)lague, hog cholera, fowl cholera, tuberculosis, etc. A 

 large part of the report is occupied with tables showing the distribution of 

 these diseases in detail. Copies are also given of various quarantine regula- 

 tions against different foreign countries. 



Sodium cinnamate and leucocytosis in anthrax in rabbits, G. Boehm (Arch. 

 Hyg., 62 (1907)., A'o. J/, pp. 3-'t3-36.'i). — The intravenous or subcutaneous injec- 

 tion of sodium cinnamate in rabbits causes a pronounceil hyperleucocytosis, but 

 their resistance to anthrax is only slightly increased by artificially increasing 

 the number of leucocytes. The blood of rabbits at the height of leucocytosis 

 ])Ossesses no bactericidal power and the number of blood plaques is not dimin- 

 ished. 



The prolongation of the period of incubation of rabies under various con- 

 ditions, C. Fermi {Arch. Farmacol. Spcr. e Sci. Aff., 6 (1907), 'No. 11, pp. 

 587-593). — As a result of dilution of rabies virus to the extent of 10,000 to 

 60,000 times, the period of incubation in inoculated animals was extended from 

 3 to 22 days. Similarly after filtration of the virus the period of incubation 

 was extended from 2 to 12 days. When rabies virus was previously treated 

 with potassium permanganate, carbonate of soda, iodin, and other substances, 

 the symptoms of rabies appeared 2 days later than in the control animals. 



Treatment of tetanus with Behring's antitoxin in veterinary medicine, 

 A. ScHOTTE (Iiiouff. Diss. Univ. Bern, 1907, pp. 163). — The literature relating 

 to cases of tetanus which have been treated by the antitoxic method is carefully 

 summarized and results presented in a tabular form to show the clinical history 

 of each case. Three cases of tetanus in horses were treated by the author 

 with antitoxin with the result that two died and one recovered after repeated 

 injections. Judging by the results thus far obtained by the author and other 

 investigators, the antitoxic treatment of tetanus in animals appears to be a 

 somewhat tedious and expensive method. 



Treatment of trypanosomiases, A. Laveran and A. Tiiiroux (Co)npt. Rend. 

 Acad. ,Sci. [Paris], l.',5 {1907), No. 19, pp. 759-7^2).— During the past few 

 years many experiments have been made in the use of various forms of 

 arsenical compounds in the treatment of diseases caused by trypanosomes. 

 Some favorable results have been obtained from the use of atoxyl, but in 

 many cases this drug has led to disappointment. In the experiments of the 

 authors, which were largely conducted on guinea pigs infected with surra, 

 results were obtained which indicate that it may be desirable to use both 

 atoxyl and arsenic trisulphid. 



Treatment of dourine, W. L. Yakimoff {Ccnthl. Bait, [etc.], 1. A7)t., Orig., 

 Jf5 {1907), No. 5, pp. Ji37-Jf50). — Trypanrot, in experiments carried on by the 

 author, was found to be a specific against the trypanosome of dourine. In 

 mice 0.5 cc. of a 1 per cent solution of trypanrot caused the complete disap 

 pearance of the trypanosomes from the blood after they had been demon- 

 strable in the blood for a period of 4 or 5 days. In order to prevent the 

 recurrence of the disease it is necessary to repeat the injections with trypanrot 

 at frequent intervals. As a curative agent for dourine trypanrot appears to 

 be of high value. It has, however, little protective power and may exert a 

 toxic influence. This has been shown to be the case in guinea i)igs. 



Dourine and a few conditions simulating it, E. T. Davison {Amer. Vet. 

 Rev., 32 {1907), No. 1, pp. Ji'i-^i9). — The etiology of dourine is briefly discussed. 

 Attention is called to the fact that a great variety of pathological conditions 

 may cause the disappearance of pigment similar to that observed in dourine. 

 This may occur as a result of chafing, alkali dust, sun scald, vesicular erup- 

 tion, bursatti, etc. It is also frequently noted in cases of so-called piuto horses.
