The influence of high pressure on micro-organisms, G. W. Chlopin and 

 O. Tammaxn {'/AHcJir. Hiifj. n. Tufertiomkrank., 4-'> {J90S), No. 3, pp. J7 1-304) .—The 

 author tested the influence of i)ressures varying from 500 kg. to 3,000 kg. i)er square 

 centimeter u])on the growth and virulence of various micro-organisms, including the 

 bacillus of mouse typhus and the anthrax bacillus. The high pressure was brought 

 about gradually and the normal pressure was then gradually restored. In experi- 

 ments with the bacillus of mouse typhus it was found that the virulence of the 

 organism was considerably reduced by subjection to a pressure of 2,000 kg. per 

 sipiare centimeter at a temperature of 36° C. In general the experiments showed 

 tliat a considerable increase of pressure lowered the vital functions of micro-organisms 

 and that these functions did not regain their normal state until after some time. A 

 pressure of 3,000 kg. per square centimeter, however, was not sufficient to kill 

 bacteria, mold fungi, or yeasts, and exercised onh' a slight innnediate effect upon 

 the micro-organisms. The effect was proportional to the length of period and to the 

 pressure, and was manifested in weaker movements, less rapid nniltiidication, less 

 active production of fermentation and jtigments, and an attenuation of the virulence. 



The death of bacteria -when boiled under diminished pressure, J. ScriiT, Jr. 

 {Zlaclir. Jhjri. n. Infect ionskrank., 44 {190S), No. 2, pp. 3.iS-3.5S, jd. l,fig!i. <7).— In these 

 experiments a considerable variety of saprophytic and pathogenic bacteria, includ- 

 ing anthrax bacilli, were used. The pnrpose of the ex])eriments was to determine 

 whether the lowering of the pressure influenced the effectiveness of a given tem- 

 perature in the destruction of micro-organisms. It was found that bacteria and 

 other spores are killed less quickly l)y subjection to a given temi)erafure without 

 boiling than by Ijeing boiled at the same time. Live steam was found to be more 

 effective in the destruction of micro-organisms than boiling water at tlie same tem- 

 perature. The experiments also showed that the resistance oi micro-organisms to 

 high temperature depends in part on the temperature at which they had Ijeen culti- 

 vated, and the medium in which they are suspended. Live steam was found to be 

 |trartically as effective at a temperature of 90 as at 100° C. 



Fourteenth annual report of the veterinary service in Hungary, F. Hutyka 

 {J(i]ii-ei<hcr. Vet. Ihic/arn, 14 {1903), pp. 135). — As u-sual in his annual report, the 

 author presents an account of the official veterinary service of Flungary, together 

 with detailed notes on the prevalence and means of combating rinderpest, anthrax,

 Yeter'murw. Kijnlgr. Sdchsm, 47 {1902), pp. 324). — This ri-port contains an account of 

 the veterinary commission, the official veterinarians of Saxony, and notes on the

Annual report of the Bacteriological Institute for the Province of Saxony, 

 H. IIakbiger (Berlin. Tiemrzil. We]iii.'<clir., 1U03, Xn. 41, jip. 630-041). — Notes are 

 given on c(jntagious vaginal catarrh of cattle and its treatment, infections dysentei-y 

 in calves, Borna horse disease, pleuro-pneumonia of cattle, swine erysipelas, swine 

 plague, fowl cholera, and the destruction of rats bj^ means of bacterial cultures. 



Bloemfontein veterinary conference, S. B. AVoollatt {Agr. Jour, and MIn. 

 Rec. [Natal'], 6 {1903), No. 23, pp. 841-843). — At this conference a lengthy discus- 

 sion on rinderpest was had and a resolution was adopted declaring that one of the 

 most important jioints in preventing this disease is the making of an immediate and 

 correct diagnosis, and that all of the governments represented at the conference 

 should at once give notification of the presence of rinderpest in their country.
