94 EXPERIMENT STATION RECORD. 



Preventive vaccination as a xaeans of combating cattle plague, A. Duduka- 



Lov {Arch. Vrt. Nmtk, 30 {1900), No. 11, II, pp. 447-452).— T\w author discusses 

 briefly the extent of this disease and the losses caused by it, and presents a detailed 

 account of the method for making preventive inoculations. 



The study of the organism of cattle plague, G. Garlichkov {Arch. Vet. Nauk, 

 SO {1900), No. 11, II, pp. 45-2-401, j\(jii. 8). — The author discusses the methods by 

 which these organisms may be obtained, and describes their behavior on different 

 culture media. 



Fat formation by different bacteria together -writh a new stain for actino- 

 myces on sections, A. Sata {Centbl. Allg. Path. u. Path. Anat., 11 {1900), No». 3-4, 

 pp. 97-102). — The author discusses the literature of this subject in connection with a 

 bibliography of a number of pathogenic organisms. A method for staining actino- 

 myces on sections is described, which depends upon the affinity of a stain known as 

 Sudan III for fatty substances. The method includes fixation in formalin, washing 

 in water, sectioning with the freezing microtome, staining with dilute hsematoxylin, 

 washing with alcohol, staining in an alcoholic solution of Sudan III for 12 to 24 hours, 

 and embedding in glycerin. 



The lesion in actinomycosis writh a few new stains for the actinomyces, 

 R. C. RosENBERGEK {JouT. Appl. Micws., 3 {1900) , No. 11, pp. 1051-1053). — The 

 author obtained good results from staining this organism with luematoxylin and 

 methylene blue. The ray forms of the organism are readily distinguished, their situ- 

 ation being usually within an area of small round cells. A clear zone suri'ounds the 

 whole mass, and beside the small round cells a number of leucocytes are usually 

 found in the tumor. 



Bacteria in milk after recovery from mammitis, J. F. Lamekis and H. G. 

 Van Harrevelt {Ztschr. Fleisch u. Milchhyg., 11 {1900), No. 4, pp. 114, 115). — An 

 investigation was instituted to determine the cause of serious diarrhoea among the 

 consumers of milk from a certain dairy. It was found that a strejitococcus was present 

 in great numbers in one quarter of the udder of the cow which had suffered from 

 mammitis but had recovered. The streptococcus was not pathogenic for rabbits or 

 guinea pigs. Itwas doubtful whetherthe organism was the original cau.se of mammitis. 

 It persisted for several days in the apparently normal milk from the quarter of the 

 udder which had previously been diseased. 



Spotted kidney in calves, K. Kavitz {Monatsh. Prakt. Thierh., 13 {1901), No. 4, 

 pp. 157-192, Jigs. S). — The author made detailed studies of this disease in calves, with 

 the following conclusions: The primary infection may be through the navel from 

 chemical toxic substances or from infections which arise in the alimentary tract. 



Diseases of sheep {Kansas Stale Bd. Agr. Rpt., 12 {1S99-1900), pp. 131-159, figs. 

 9). — Brief accounts are given of the desirability of the practice of fall dipping. Bul- 

 letin 21 of the Bureau of Animal Industry on sheep scab is reprinted in part, and short 

 notes are presented on ticks, lice, foot rot, stomach worms, hmgworms, tapeworms, 

 and the sheei> bot fly. 



Diseases of sheep, W. A. Rushworth {The sheep. Ihiffahi, N. Y.: Buffalo Review 

 Co., {1S99), pp. 143-404, figs. 12). — The greater part of this volume is devoted to a 

 discussion of the diseases of sheep, including those of the brain and nervous system, 

 respiratory and digestive tracts, skin diseases, and specific contagious affections. 

 Recommendations are made with regard to the treatment of the various sheep 

 diseases, and formulas for the approved remedies are given. A general discussion is 

 given as to the subject of Federal and State inspection of sheep. 



The micro-organism of sheep pox, F. J. Bosc {Compt. Rend. Soc. Biol. Paris, 

 53 {1901), No. 1, pp. 9, 10). — The author made an investigation of cases of sheep pox 

 for the purpose of studying the micro-organism which causes this disease. Pustules 

 in the skin and other tissue were fixed in corrosive sublimate and acetic acid, and 

 sectioned. In the skin pustules the micro-organism was found in epithelial cells of
