Anthrax, A. T. Iseale ET AL. ( Delaware Sta. Rpt. 180:"), j^p. ^3-4G). — 

 A bistory is given of epidemics of anthrax in Delaware. It is thought 

 probable that anthrax may have been introduced into the State in 

 goat skins from South America which were unloaded on the banks of 

 the Delaware Eiver. As the result of numerous experiments made to 

 control anthrax by vaccination, reported in a general way, the author 

 states that vaccines which may be used with impunity are available at 

 the station, and tliat they afford almost complete protection against 

 anthrax to cows at i)asture upon infected meadows. 



The details are given of 14 tests of the efficiency and safety of vac- 

 cines made at the station. The data in some instances are tabulated. 



On the germicidal po-wer of menthol vapor and its action on 

 the development of anthrax, 1\ ]). Chester {J>e]aivar<' St((. Bpt. 

 1895, p}}. 118-121, Jig. 1). — The author investigated the germicidal power 

 of menthol, using in his experiments a spore- forming bacillus, Bacillus 

 anthracis, and a nonspore form, B. coli communis. The cultures were 

 made on agar slants. Anthrax spores were not killed after 11 days' 

 exposure to menthol vai^or. The vapor prevents the formation of 

 S])ores and repeated growth under the action of menthol vapor resulted 

 in a degenerate form of sporeless anthrax in which involution forms 

 predominate. Cultures from such sporeless forms will under normal 

 conditions produce spores. 



The tests with Bacillus coli communis showed that menthol vapor 

 does not appear to prevent or even check its growth. 



Tetanus or lockjaw in horses, A. T. Neale et al. {Delaware Sta. 

 Rpt. 1895, pp. 51, 5,2). — A horse receiving a nail puncture in the foot 

 suffered 5 days later from an attack of tetanus. He was treated to 

 subcutaneous injections of the blood serum of a horse which had 

 recovered from tetanus. At the end of 22 days the horse convalesced. 

 It required 1 lb. of serum per 1,000 lbs. of live weight of the subject. 

 The expense for the serum in this case was $50. 



Bovine tuberculosis, A. T. Neale et al. {Delaware /Sta. Bpt.l895j 

 pp. 52-60). — Herd testing in Delaware is discussed, followed by remarks 

 on tests of the efficiency of the tuberculin prepared at the station and 

 on the question as to whether the effect of tuberculin on incipient 

 bovine tuberculosis is curative. Under the latter head an instance is 

 given of a Guernsey heifer 2 years old, condemned by the tuberculin 

 test in 1893, which was subjected to repeated injections of tuberculin 

 until she wholly ceased to respond and in 1895 was in excellent condi- 

 tion, having been vaccinated in the meantime with attenuated anthrax 

 virus.
