l i O EXPERIMENT STATION RECORD. 



Compilation of analyses of fodder articles and dairy products, made at 

 Amherst, Mass., 1868-1905, E. B. Holland and P. H. Smith {UdnHachmeUs 

 Sta. L'pt. 1905, pp. 200-223). — These tables show the composition, digestibility,

VETERINARY MEDICINE. 



Characteristics of some of the contagious and infectious stock diseases, 

 A. W. BiTTiNc iuul G. U. KonEUTS {Iiuliuiia Sta. Bill. 113, pp. 209-2SS, pgs. 20).^- 

 The purpose of the present bulletin is to present an outline of the chief symp- 

 toms and post-mortem lesions observed in the common diseases of live stocli. 

 The most approved lines of treatment in the case of each disease are given, and 

 mention is also made of State and Federal laws relating to these diseases. 



How parasites are transmitted, B. H. Ransom ( f7. ^.' Dept. Agr. Yearbook 

 1905, pp. 139-166, fig.s. 50). — The parasites referred to in this article are grouped 

 into arthropods, roundworms, tapeAAorms. flukes, and protozoa. Examples are 

 given of these various classes of parasites, with notes on their life history and 

 the means by which tbey are transmitted from one animal to another. 



The transmission of tuberculosis from man to cattle, A. Eber {Berlin, 

 Tieriirztl. Wc]tii.scJrr., 1906, Xo. 28. pp. 527-537). — A critical review is given of 

 the literature relating to this highly controversial problem. The author exam- 

 ined carefully the evidence presented by Koch for his belief in the nonidentity 

 of human and bovine tuberculosis. The experiments carried out by the German 

 Imperial Health Office are believed not to, support the contentions of Koch. 



Human tuberculosis cultivated in vivo in domestic animals, G. Moussu 

 (Coiiipt. Rend. Soc. Biol. [Paris], 61 {1906), No. 26, pp. 95-97).— ^X hen cultures 

 of human tubercle bacilli were suspended in the intestinal cavity' of cattle and 

 other animals it was found that these animals would soon give a reaction to 

 tuberculin, which existed for a year or more, although no true infection took 

 place. 



Milk and dairy products as sources of infection in tuberculosis, O. MIjller 

 {.Jour. Compar. Path, and Titer.. 19 {1906), No. 1, pp. 19-33).— As a result of a 

 study of the literature of this subject, together with personal observations and 

 experiments, the author believes that the infectiousness of milk is chiefly refer- 

 able to tuberculosis of the udder and that cows in which the udder is not affected 

 do not excrete tubercle bacilli or at least only to a very slight extent. The 

 transmission of tuberculosis, therefore, takes place through the milk of cows af- 

 fected with the mammary form of the disease. In cases, however, in which the 

 disease has reached an advanced stage without affecting the udder, tubercle 

 bacilli may be found in the milk. The disease prevails especially in dairy 

 regions among calves and pigs, and in order to avoid danger from its further 

 dissemination it is necessary to observe great cleanliness about the dairy and 

 sterilize all milk of tuberculous cows before feeding to calves or pigs. 



The milk of tuberculous cows, G. Moussu {Arch. Wiss. u. Prald. TierJieilk., 

 32 {1906), No. 3, pp. 279-29J,, pis. 2).— In this article particular attention was 

 given to the study of the origin of tuberculous mammitis. The litei'ature re- 

 lating to this subject is briefly reviewed and notes are given on the pathological 

 changes produced in the udder after tul)erculous infection. 



As a result of the author's investigations it is concluded that the milk of all 

 tuberculous cows shoulc' be excluded from utilization without previous treat- 

 ment. This is considered necessary on account of the fact that mammary 

 tuberculosis can not be recognized or diagnosed in its early stages. Apparently 

 the disease assumes such similar forms and such a similar course iu both man
