Th« most vigorous (levolopniL-nt was ohUiiiu'd from the use of blood serum of slieep, 

 cattle, and man, to which lactii; ai-id had l>een added in the proportion of 10 <lrops 

 of a 1 per cent solution to 50 vr. of blood .serum. The l)lood serum should jjive a 

 neutral reaction with Htmus paper l)eforo the lactic acid is added. The most rapid 

 growth was ()l)tained l)y the use of human l)lood serum, treated as just described. 

 Tlie author concludes from his experiments that for the culture of tlie tubercle 

 bacillus a slightly acid medium has a beneficial influence. In media jtrepared from 

 meat juii-es the normal acid condition of such juice is very suitable. In the case of 

 media which are naturally alkaline or neutral, good results are obtained by the 

 addition of lactic acid. 



Danger from tuberculous animals, K. Xoc.vku (Bui. Arjr. AUjcrie el Tnume, 

 6 {1900), No. 24, pp. 671-681).— The author discusses the general problems of the 

 danger of transmission of tuberculosis from animals to man through close association 

 and eating meat and milk products. It is stated that none of the meat of tul)ercu- 

 lous animals should be offered for sale without being properly labeled. It is recom- 

 mended that the various milk products from tuberculous animals should l)e offered 

 for sale only after i)astenrization at a temperature of at least 85° C. It is also sug- 

 gested that tulxTculosis of pigs and goats should be added to the lists of contagious 

 diseases under the supervision of sanitary ofhcers. The danger from the use of milk 

 from tuberculous animals is believed Ijy the author to be much overestimated. 



On the seizure and condemnation of tuberculous meat, J. M. Wilson, 

 J. W. Mason, and F. W. Maktin {Public Health, 13 {1901), No. 5, pp. 351-358).— 

 The authoYs present a discussion concerning the attitude which should be adopted 

 by sanitary officers with respect to the condemnation of tuberculous meat, especially 

 that of animals in which the disease existed in its earlier stages. The authors sug- 

 gest the i)ractical difficulties of convincing the owners of such animals of the danger 

 of eating the meat, provided the disease was apparently confined to the lungs, liver, 

 or other internal oi'gans. 



IjCgislation ■with reference to bovine tuberculosis, 1). E. Salmon ( V. ,S. Ikpt. 

 Ayr., Bureau of Auimal Industry Bui. ii8, pp. 173). — This bulletin contains a compi- 

 lation of the laws, rules, and regulations of the different States and Territories with

International congress for the consideration of the best methods for check- 

 ing or curing tuberculosis, E. A. de Schweinitz ( l\ S. Dept. Ayr., Bureau of 

 Animal JuduKtri/ Rpt. 1899, pp. 126-133. — This article contains an account of the 

 delegates and the work of the congress, and brief abstrac:ts of the more important 

 papers read during the sessions. 



Anthrax produced in animals by mixing anthrax spores with their regu- 

 lar feed, NiKoLSKY {Ann. Ind. Pasteur, 14 {1900), No. li, pp. 794-801). — The author 

 began his experiments on 5 white rats by feeding bread which had been si)rinkled 

 with an emulsion containing anthrax spores grown on gelatin without pej)tone, at 

 a temperature of 37° C. Tlie rats resisted infe<;tion for a consiilerable time. At the 

 end of 1() days 2 died, 1 on the following day, and 2 on the twenty-first day. An 

 autopsy showed that these animals died of anthrax. In all cases the liver and 

 spleen were enlarged, and a microscojncal examination showed the presence of 

 anthrax bacillus in the blood. Similar experiments on gray rats gave negative 

 results, as these animals were not infected after feeding with the spores for over a 

 month. The author conducted similar experiments upon rabbits, which were killed 

 at varying periods after feeding with anthrax spores. The conclusions drawn from 

 these experiments are that animals which receive ordinary fodder infected with 

 anthrax sjxjres develop anthrax as certainly as by any other juethod of infection. 

 The spores develop in the ctrntent^ of the intestines in spite of the antagonism of 

 other micro-organisms, and penetrate the walla of the intestines and the lymi)liatic 

 vessels, and finally enter the blood.
