202 EXPERIMENT STATION RECORD. 



with the age of the material, being less in older material. Attenuation of the mate- 

 rial diminished the number of Bpores. Several species of saprophytic organisms 

 were found in blackleg vaccine. Some of these are usually found in healthy cattle. 



Vaccination against blackleg by the method of O. Thorn s in Verdun, A. 

 Guillebeat (Schweiz. Arch. Tierh., 46 (1904), No. 2, pp. 57-01). — The author refers 

 to the recent introduction of "blacklegine" into Germany and to the claims which 

 have been made regarding its efficacy. The experience thus far had with this 

 method does not seem sufficient, and the author prefers to wait for further data before 

 coming to a final conclusion as to the value of the remedy. 



Foot-and-mouth disease, Gray ( Rhodesian Agr. Jour., 1 ( 1004), No. 4, /i/t.83, 84. )— 

 The author describes the symptoms and lesions of this disease in various animals, 

 including camels. 



Intravenous treatment of foot-and-mouth disease, G. Mazzini ( Gior. J!. Soc. 

 edAccad. Vet. Hal., 53 {1904), Nos^ 2, pp. 31-37; 4, pp. 79-84; 6, pp. 181-136; 8, pp. 

 175-182; 9, pp. 200-203). — A summary is presented of the results obtained in the 

 intravenous use of corrosive sublimate in treating foot-and-mouth disease in France, 

 Germany, Belgium, Roumania, Switzerland, Spain, Portugal, and Italy. From this 

 elaborate review of the literature of the subject it is concluded that the method is 

 worthless. 



The pathogenic action of certain Streptothrix (Actinomycosis) species, F. 

 Saifelice {Ceritbl. link!. //. Par., 1. Alt., Orig., 30 (1904), No. 3, p]>. 355-367 ') .—The 

 author presents a systematic classification of this group of micro-organisms, with notes 

 on the pathogenic action of various species. It was found to be impossible to obtain 

 by inoculation of dogs a serum wdiich would increase the resisting power of rabbits 

 to infection with actinomycosis. 



Hematuria in cattle, Detroye (Bv 1 c ' -. Cent. Med. Yet., 81 (1904), No. 0, pp. 

 187-193). — Positive results were obtained in 10 out of 17 cases in which it was sought 

 to transmit the disease by direct inoculation. Detailed notes are given on the tech- 

 nique of these experiments. 



Malignant catarrhal fever of cattle, Iseppoxi (Schweiz. Arch. Tierh., 46 i 1904), 

 No. 1, pp. 1-12). — An outbreak of this disease occurred in which the symptoms were 

 not of the usual nature. From his study of the disease the author concludes that 

 it occurs sporadically or sometimes as an enzootic. 



The disease may be mistaken for foot-and-mouth disease, rinderpest, meningitis, 

 and dysentery. It is apparently not communicable immediately from animal to 

 animal. The pathogenic organism is found in the soil, where it retains its virulence 

 for long periods. When affected animals are killed before the croupous-diphtheritic 

 symptoms appear the meat is suitable for food. The disease is fatal if allowed to 

 reach full development. It may be controlled by quarantine, thorough disinfection, 

 and serum treatment. 



Inoculation against pleuro-pneumonia, sequels and complications, A. 

 Theiler (Transvaal Ayr. Jour., 2 (1904), No. 7, pp. 357-368, pi. 1).— An elaborate 

 historical account is given of the methods of inoculation against this disease. The 

 methods o^ vaccination are described and notes are given on their effect upon healthy 

 cattle. Complications from inoculation are often manifested by lesions in the throat, 

 peritoneum, or elsewhere. In the author's experience the duration of artificial 

 immunity is about 1 year, occasionally 18 months. 



Trichophyton tonsurans of cattle, Poenaru (Bui. Soc. Cent. Mid. Vii., 81 (1904), 

 No. 10, pp. 328, 329). — This disease may be transmitted from cattle to man, but such 

 is not commonly the case. The author classifies Trichophyton tonsurans with the 

 yeasts. 



The operative treatment of skin warts on cattle, M. Strebel (Schweiz. Arch. 

 Tierh., 46 (1904), No. 1, pp. 12-17). — Warts appear most frequently on young cattle, 

 and preferably on the udder, inner surface of the thighs, and lower parts of the
