402 EXPERIMENT STATION RECORD. 



plants. Special reports are presented by C. H. Higgins and various inspectors in 

 different parts of the Dominion of Canada regarding cattle dips, tuberculin, vermi- 

 nous bronchitis in hogs, poultry diseases, etc. 



The actual conceptions of experimental pathology, Charrin (Rev. Sci. 

 [Paris], 5. ser., 3 (1905), No. 10, pp. 289-296).— In this article the author presents 

 definitions of many terms and conceptions used in the literature relating to general 

 pathology. 



Immunization as a means of controlling contagious diseases, J. B. Tiffany 

 (Mo. Bd. Ayr. Mo. Bui, 4 I 1905), No. 9, pp. 46-50). — A brief discussion is presented 

 of the field of immunization as at present understood with particular reference to 

 anthrax, blackleg, tetanus, and hog cholera. 



Anaerobic bacteria in the intestines of cattle, J. Neubatjer (Arch. Wiss. u. 

 Prakt. Tierhettk., 31 (1905), No. 1-2, pp. 153-176).— The literature relating to this 

 subject is discussed in a critical manner in connection with a short bibliography. 



The results of the author's experiments and study may be briefly stated as follows: 

 Anaerobic bacteria in the large and small intestines of cattle are rare. They occur 

 more frequently, however, in the large than in the small intestines. No bacidi or 

 spores of tetanus or malignant edema were found in the intestines. The vegetative 

 forms or spores of anaerobic bacteria taken up in the food are usually destroyed in 

 the stomach or duodenum. 



The pathogenic action of parasites in the intestines, J. Guiart (Arch. Par., 

 9 (1905), No. 2, pp. 175-1S6). — According to the author's investigations parasites 

 may cause harmful effects in 3 ways: By irritating the end organs of the intestinal 

 nerves, by secreting the toxins which destroy the red corpuscles and hemoglobin, 

 and by producing ulcerations of the intestinal mucous surfaces thus giving opportu- 

 nity for infection with pathogenic bacteria. 



An infectious pneumonia of rabbits and its control by means of an anti- 

 serum, H. J. Sudmersen (Centbl. Bald, [etc.'], 1. Alt., Orig., 38 (1905), No. 3, pp. 343, 

 344). — From cases of pneumonia in rabbits the author isolated a bacillus which evi- 

 dently belongs to thecoli group and which develops a very active toxin in cultures of 

 bouillon. The organism may be destroyed by subjection to a temperature of 60° C. 

 for 10 minutes. It was found that cultures thus destroyed exercised a decided vac- 

 cinating action when injected into rabbits. After repeated injections with dead 

 cultures the blood of rabbits contained pronounced agglutinating and bactericidal 

 properties sufficient to immunize the animal. 



Furonculine, G. Mitrowitsch (Berlin. Tierdrztl. Wchnschr., 1905, No. 5, pp. 

 77-80). — Furonculine is a name given to a form of beer yeast used in the treatment 

 of animal diseases on account of its supposed antiseptic properties. It is recom- 

 mended that it be administered by way of the mouth. 



The author describes the powder form in which the material is ordinarily sold, 

 and reports upon culture experiments made with this material. A number of bacilli 

 and streptococci were obtained from this substance and the material proved to be 

 pathogenic for mice and rabbits after administration by the intraperitoneal or subcuta- 

 neous methods. The author states that in his practice a number of cases of animal 

 diseases have occurred in which he tried furonculine without any satisfactory results. 



The remedy appeared to have no beneficial effect in the treatment of rabbits arti- 

 ficially inoculated with streptococci, and among 26 horses treated for contagious 

 coryza one died of pyemia, while the majority of the rest had to be treated by sur- 

 gical operation. 



Investigations concerning lysoform, B. Promnitz (Fortschr. Vet. Hyg.,2 (1905), 

 Nn. 11, pp. 281-295). — The appearance and chemical composition of lysoform are 

 described in considerable detail, together with notes on its bactericidal properties 

 toward various pathogenic organisms, including anthrax spores and the organisms of 

 malignant edema, blackleg, hog cholera, and fowl cholera.
