isolated from the healthy animals. The barn was disinfected as thoroughly as pos- 

 sible l)y means of crude carbolic acid, 1 part in 20 of water. The tuberculin test was 

 applied to the nonreacting herd once or twice a year, and the author !)elieves that it 

 is necessary to test as often as this. During the furthei- course of the experiment 93 

 animals were tested within 3 years. It was found that no constant differences^ 

 existed among different breeds with regard to the susceptibility to tuberculosis, since 

 20 per cent of the Jerseys were affected, 26 per cent of the Guernseys, 21 per cent of 

 the Ayrshires, and 20 of the Holsteins. It was found that the heavy milkers were 

 no more susceptible to tuberculosis than the least productive cows. The evidence 

 obtained from the herd showed that the disease is not inherited, no case of tubercu- 

 losis having appeared in 17 calves reared from the tuberculous animals. Repeated 

 injections of tuberculin were found to produce a temporary insusceptibility to the 

 test. Great indivi<lual differences in resistance to the progress of the disease weie 

 noted in different animals. The author believes that Bang's method of isolation is 

 economical and effective. 



Contributions to our knowledge of bovine tuberculosis, J. Nelson (Neir Jersey 

 Stas. Rpt. 1901, pp. 352-381).— 'Sotes are given on autopsitis on 2 cows which were 

 affected with tuberculosis. Extensive tables are presented showing the variations in 

 temperature of tuberculous cattle from February to June, and also showing the 

 record of abortions in the college herd. It is stated that the number of abortions is 

 decreasing, but the cause is not well understood. The record of temperatures of 

 tuberculous cattle in the hosjiital herd fails to indicate that specially favorable con- 

 ditions for infection are found in the stables where the animals are kept. 



The use of eggs as a medium for the cultivation of Bacillus tuberculosis, 

 M. Dorset {Aiiier. Med., 3 {1!)02), Xo. 14,pp. oo5,o56). — During the author's experi- 

 ments a medium consisting chiefly of hens' eggs prepared in 3 ways so as to include 

 the whole egg content, the yolk of the egg alone, or simply the white alone, was 

 tested. Unusually rapid development of the tubercle bacilli took place on thes? 

 nutrient media, especially on the whole egg medium. Growth was usually quite 

 apparent by the end of 7 or 8 days, and conspicuous colonies of bacilli were to be 

 observed after a lapse of 10 to 14 days. The egg medium possesses the advantages of 

 causing the rapid growth of the tubercle bacillus and of being easily prepared. It 

 does not cause quite so rapid and abundant growth as secured by Ficker from pure 

 cultures on brain medium. 



Treatment of anthrax, MoBirs {BerUn. ThierarzU. Wchnschr., 1902, No. 14, pp. 206, 

 207). — The author calls especial attention to a number of cases of anthrax in man 

 which have arisen from carelessness in handling the carcasses of animals dead of 

 anthrax, or from unnecessary inspection or examination of these carcasses. It is 

 recommended that no dissection or other examination of animals dead of anthrax 

 should be made, after diagnosis is fairly certain. This recommendation is made on 

 account of the great danger of becoming infected with anthrax, even when only the 

 most minute skin lesions are to be found on the hands. 



Recovery of a cow from anthrax, W. Ort.mann {Berlin. ThierarzU. Wdinschr., 

 1902, No. 8, p. 125). — One animal in a small herd of cattle died of anthrax, and on 

 the next day another cow manifested similar symptoms. In the treatment of this 

 case the author ufel intravenous injections of colloidal silver, and administered 1 

 spoonful of lysol in a bottle of water hourly; after 2 days, naphthaline, bicarbonate 

 of soda, and gentian root were administered. Complete recovery took place. 



The intravenous application of corrosive sublimate, Schmidt (Berlin. Tltier- 

 drzlJ. Wchnselir., 1902, No. 12, pp. 181-184). — The author couducted a number of 

 experiments, for the most part on small experimental animals, which were infected 

 with anthrax and fowl cholera. As the result of these experiments it was tound that 

 the injections of corrosive sublimate did not produce any general reaction of the
