Annual report of the veterinary service for the year 1914, W. Littlewooi) 

 (Ann. Rpt. Vet. Sen:. Egupt, 1914, pp. 49, pJ. 1). — This report deals with the 

 occurrence and work of the year with contagious diseases of animals, the work 

 of the veterinary pathological laboratory, etc. 



The disinfection of tannery efSuent containing' anthrax spores, .T. Wintees- 

 EERGES (Wiener Tierarztl. Jlonafsschr., 2 (1015), No. 8. pp. 553-379 ) .—Experi- 

 mental data submitted show that only in isolated cases and under the most 

 favorable conditions is a complete disinfection possible by the use of from 0.1 

 to 0.2 per cent chlorid of lime solution after contact from two to four days. 

 By the use of 0.5 per cent chlorid of lime anthrax spores could be destroyed in 

 the majority of the tests reported in three days. Such results, however, were 

 not consistently reproducible or uniform. The disinfectant value increases with 

 the concentration of the material used, a complete destruction of anthrax spores 

 being obtained in three days by the use of 2 per cent clilorid of lime. 



It is indicated that since the conditions in practice are not so favorable as 

 experimental conditions the use of the disinfectants of stronger concentrations 

 and for prolonged periods of contact is the safest procedure. 



The addition of hydrochloric acid markedly increased the disinfectant strength 

 of the chlorid of lime, and the procedure is deemed to be of practical value. 

 The economical aspect in cases where a highly alkaline water is used would, 

 however, have to be considered in the use of the acid. 



Formaldehyde Avas found to be more active than chlorid of lime, but the cost 

 when used in concentrations of from 0.5 to 1 jter cent would be a disadvantage. 



The data obtained in the use of various lime-vat mixtures confirm earlier 

 investigations that by their use a partial destruction of spores is possible if the 

 period of contact is prolonged. The spent mixtures were, however, often found 

 to contain virulent spores. 



The earlier observation that chlorid of lime exhibits a greater affinity for 

 dead organic matter than for living material was confirmed. 



The strength and composition of blackleg vaccines, O. M. Franklin and 

 T. P. Haslam (Jour. Infect. Diseases, ID (1916), No. S, pp. ^OS-^io).— This is 

 a report of investigations made at the Kansas Experiment Station on the 

 strength and composition of some of the most widely known blackleg vaccines. 



The results show that the powdex'-form vaccines must be given in amounts of 

 from 20 to 150 mg. to kill a guinea pig. INIost of the commercial pellets were 

 not fatal to guinea pigs in doses of three pellets per animal. Pellets which 

 are too virulent produce severe vaccination losses. 



" The pseudoblackleg bacillus differs from Bacillus chauvm in its pathogenicity 

 in rabbits, in the formation of a putrefactive odor, in the size and appearance 

 of the colony in pure culture, in the gas formula, in the blackening of iron- 

 sulphate agar, in the pathogenicity in giiinea pigs highly immune to blackleg, 

 and in the failure of blackleg immune serum to protect guinea pigs against a 

 lethal dose of pseudoblackleg culture or a B pellet." 



The ophthalmic test for glanders, with a simplified method, of procedure, 

 N. S. Ferry (Jour. Amer. Vet. Med. Assoc., 50 (1916), No. 1, pp. 41-46).— Tha 

 te.sts commonly used for the diagnosis of glanders and the requirements of a 

 most satisfactory diagnostic test are briefly reviewed. 



The method proposed by the author consists of preparing a desiccated mallein 

 by precipitating the crude mallein with several volumes of absolute alcohol.
