and animals from drinking milk freely, whether such milk comes from tuberculous 

 or nontuberculons animals. The author believes that the good results which are 

 supposed to accrue from a free use of the tuberculin test are much exaggerated by 

 the advocates of this process for exterminating tuberculosis. It is considered that 

 the losses occasioned by the application of the tuberculin test and the enormous 

 expense, in connection with serious doubts as to the necessity for guarding against 

 the transmission of tuberculosis from animals to man, are serious obstacles to the gen- 

 eral use of tuberculin. The author suggests a method by which veterinary surgeons 

 are appointed in control of specified districts for the purpose of inspecting all cattle, 

 and destroying or quarantining those which show outward signs of tuberculosis. 



Tubercle bacilli in cows' milk as a possible source of tuberculosis disease 

 in man, J. McFadvean {Vet. Jour., 53 (1901), No. 314, pp. 83-91).— The author 

 presents a review of the subject, calling attention especially to the arguments which 

 tend to prove the identity of bovine and human tuberculosis. An attack is made 

 upon the arguments of Koch before the British Medical Association, and it is urged 

 that no relaxation should be allowed in the measures to prevent the transmission of 

 tuberculosis from lower animals to human beings. It is admitted that tuI>erculosis 

 of cattle is usually contracted from tubercle bacilli of bovine origin, while that of man 

 is similarly transmitted, for the most part, by means of bacilli of human origin, but 

 the identity of human and bovine tuberculosis is still maintained as highly prol)al)le. 



Tuberculosis and the milk supply, J. A. W. Dollar [Vet. Jour., 53 {1901), 

 No. 314, PP- 100-106). — The literature of this subject is carefully reviewed, with 

 especial reference to the extent to which tubercle bacilli are found in tlie milk of 

 dairy cattle. The author ])elieves that milch cows and goats should be placed under 

 regular and periodical inspection, that the sale of milk from tuberculous animals for 

 human use should be forbidden in all cases where physical evidence of tuberculosis 

 is present and in cases of tuberculosis of the udder. 



Tuberculosis in the State ofVictoria, G. Pentland ( Yet. Jour., 53 {1901), No. 

 315, pp. 176-1S3). — The author reviews the history of the origin and distribution of 

 tuberculosis in Victoria. Statistical tables are presented showing the extent of 

 tuberculosis. No indemnity has been granted for condemned animals, but no trouble 

 in this line has been experienced, since the owners have considered such animals 

 valueless. The present districts over which inspectors have charge are considered 

 too large for the most effective inspection and quarantine. 



Legislation suggested for controlling and eradicating tuberculosis in ani- 

 mals, D. McEaciiran {Vet. Jour., 53 {1901), No. 314, pp. i/6^-i5-?).— In this article 

 the author discusses heredity, diagnosis of tuberculosis, tuberculin test, its reaction, 

 various objections which have been urged against the tuberculin test, the different 

 methods of making the test adopted by different countries, quarantine regulations for 

 breeding stock, fat cattle and settlers' cattle. State legislation with reference to bovine 

 tuberculosis in the United States, the danger from milk and meat of tuberculous 

 animals, means for previ^nting the introduction of tuberculosis into the herd, disin- 

 fection of iiremises, and the payment of indemnities for condemned animals. 



The relationship of tubercle bacillus to other acid-proof bacteria and acti- 

 nomyces, A. Moellkk ( CentU. Bukt. k. Par., 1. Aht.,30 {1901) , No. 14, pp. 513-523).— li 

 has for some time been considered impossible to definitely identify the tubercle bacillus 

 by a simple microscopic examination, for the reason that this bacillus can no longer be 

 considered the only acid-proof and alcohol-proof species of bacteria. Similar proper- 

 ties are possessed by the smegma bacillus, leprosy bacillus, and the organisms which 

 cause tuberculosis of cold-blooded animals and of birds. It has been shown, further- 

 more, that the tubercle bacillus is not always acid-proof, even when taken directly 

 from sputum or from tubercles of bovine origin. The author isolated a bacillus from 

 the tubercles taken from an animal suffering from a typical form of pearl disease, 

 and found that this organism was absolutely acid-proof and alcohol-proof. The
