rabbits, and wbite mice. None of the experimental animals developed tuberculosis 

 or were affected to such an extent as to give evidence of any serious disease. Some 

 of the animals were killed, and a post-mortem examination gave evidence of a 

 peculiar pathological appearance in the liver of a few, while no evidence was 

 obtained for tlie presence of tubercle bacilli. 



Measures for preventing the transmission of tuberculosis in tlie milk of 

 cattle, Marsac {Jour. Agricole [Paris'], 12 {1901), No. 137, jop. 143, -?-^^).— The 

 author considers the danger from this source of sufficient importance to warrant the 

 putting forth of every effort to prevent the spread of contagion in milk. He has 

 recommended that a special scientific corps be appointed for this work, that public 

 and private schools be interested in the movement, that milk dealers be compelled 

 to register and submit their products for examination, and that the names of 

 approved dealers with healthy animals and good milk be published from time to 

 time. 



Indemnities for tuberculous cattle, A. Laquerriere {Jour. Agricole [^Paris], 12 

 {1901), No. 138, pp. 151-154) . — The author discusses this problem from various points 

 of view, and comes to the conclusion that in cases of animals which are totally con- 

 demned the loss should fall upon the seller. In the cases of partial condemnation 

 the contract may be allowed to hold, but the buyer should be reimbursed for the 

 amount of his loss, as determined by the inspector who condemned the meat. 



Interesting' diseased-meat case in Edinburgh {Vet. Jour., 52 {1901), No. 311, 

 pp. 267-275). — This article contains a detailed report of a case of prosecution for 

 selling meat susjiected of being tuberculous. The evidence obtained by experts 

 from a microscopic examination of the meat was considered as proving that the 

 meat was tuberculous, but the defendant succeeded in establishing the point that 

 he had no reason for suspecting the meat and could not have known that it was 

 tuberculous. 



Bibliography of literature on tuberculosis {Rev. Tuberculose, Paris, 8 {1900), 

 No. 2, pp. 268-209) . — A classified list of titles of literature relating to tuberculosis of 

 man and animals pul:)lished during the year 1900. 



Public veterinary service, Metzger {Deut. Tierdrzll. Wchnschr., 9 {1901), No. 

 21, pp. 215-217). — During the year 1900 preventive inoculation for swine erysipelas 

 according to the Lorenz method was made on 15,208 hogs. So far as reports were 

 received, injurious effects were noted in only 3 cases as a result of the inoculation. 

 The vaccine material is furnished at a very moderate price for private use, but only 

 to veterinarians, who are under obligation not to use the material outside of the 

 country. 



A map is given showing the distribution of foot-and-mouth disease in Germany 

 at the end of April, 1901, and brief notes are presented on the success which has 

 been obtained in fighting sheep scab and on the prevalence of blackleg during the 

 year 1899. 



Concerning the existence of sensitizing substances in antibacterial sera, 

 J. BoRDETand O. Gengou {Ann. Inst. Pasteur, 15 {1901), No. 5, pp. 289-302) .—The 

 authors investigated the question concerning the existence and relationship of alexins 

 and sensitizing substances as found in normal and immunized sera. Experiments 

 were conducted on sera obtained from various sources, including guinea pigs vacci- 

 nated against anthrax, horses vaccinated against swine erysipelas, guinea pigs 

 immunized against typhoid fever, and human typhoid fever patients in convalescence. 

 From these experiments it is concluded that specific sensitizing substances are of 

 constant occurrence in organisms which have been subjected to vaccination. These 

 s':.bstances are not so readily influenced by heat as are the alexins and do not exert 

 any direct injurious influence upon the bacterial organisms. Their effect upon 

 bacteria is to cause the latter to absorb the alexins by which they may be ultimately
