ber of cases of boviue tuberculosis, glanders, and rabies in IMassachusetts for 

 the 10-year period ended 1918. 



Report of proceeding's imder the diseases of animal acts, with returns of 

 the exports and imports of animals for the year 1917, D. S. Prentice {Dcpt. 

 Agr. and Tech. In.str. Ireland, Kpt. Diseases Aiiim., JOll, pp. 30). — The usual 

 annual report (E. S. R., 38, p. ISO). 



Veterinary service and meat inspection in Norway in 1917 (Norges Off. 

 8tatis., 6. ser., 1917, No. 148, pp. T'7/+,?/3).— The usual annual report (E. S. 

 R., 39, p. 787). 



Veterinary research, annual report of director, 1916-17, A. Theiler {Union 

 8o. Africa Dept. Agr. Rpt. 1916-17, pp. //.7-50).— A brief statement of investi- 

 gations carried on during the year. 



Report of the government bacteriologist, C. J. Pound (Ann. Rpt. Dept. 

 Agr. and Stock [Queensland], 1915-16, pp. 88-91, pi. 1). — Included in this re- 

 port of work of the year are accounts of further observations with reference 

 to alleged tick-resisting cattle, the fertility of ticks matured on so-called re- 

 sistant cattle, and further observations on the life history of the warble fly 

 (Hi/podernia hovis). 



Studies in forage poisoning. — The relation of B. botulinus to forage poison- 

 ing or cerebrospinal meningitis in horses, R. Gkaiiam and A. L. Brueckneb 

 (Jour. Bact., 4 {1919), No. 1, pp. 1-21, figs. 4).— This is a report of investiga- 

 tions, a reference to which has been previously noted (E. S. R., 39, p. 387). 



"A goat injected with sublethal doses of broth culture of the bacillus (ss) 

 isolated from the silage developed an antitoxic serum which, injected intra- 

 peritoueally, apparently protected guinea pigs against a fatal amount of the 

 lioniologous toxin per os. The protective nature of the goat serum was also 

 observed in guinea pigs receiving fatal amount of B. hotulinus per os. 



"j5. botulinus antitoxic serum prepared from a mule and injected intra- 

 peritoneally into guinea pigs apparently provided a protection against 10 times 

 the lethal amount of the culture filtrate of the bacillus (ss) isolated from the 

 silage and against 5 times the lethal dose of the iinfiltered broth culture. 



" Two horses ingested in wholesome feed 2 cc. broth culture of the bacillus 

 (ss) isolated from the silage and were apparently protected by an intra- 

 venous injection of hotulinus antitoxic serum. A control horse receiving a 

 similar amount of the uufiltered broth culture manifested clinical symptoms 

 of forage poisoning and died. Post-mortem examination revealed gross ana- 

 tomic lesions analogous to some of the gross lesions obsi-rvcd in animals natu- 

 rally afflicted with forage poisoning. 



" Serum immune to B. hotulinus possessed a positive agglutinating potency 

 toward the homologous strain, as well as toward the bacillus (ss) isolated 

 fi'om the silage. The agglutinins present in serum immune to the bacillus (ss) 

 isolated from the silage were active against B. hotulinus as well as against 

 the homologous strain. 



" The cultural, morphological, pathological, and serological relation observed 

 between B. lioluUniis and the bacillus isolated from the silage in preliminary 

 experiments are suggestive of the possible etiologic significance of B. botulinus 

 or closely allied anaerobes in some outbreaks of forage poisoning or cerebro- 

 spinal meningitis in horses." 



Report of the department of chemistry, C. A. Jacobson {Nevada 8ta. Rpt. 

 1918, pp. 39-.'f/i, figs. 3). — This report relates to investigations made with a 

 view to isolating and characterizing the toxic constituent of a species of death 

 camas which occurs in Nevada and is (juite different from Zyyadenus interme-
