VETERINARY SCIENCE AND PRACTICE. 



Veterinary science and bacteriology, A R. Wahd {('idijornin Sta. Rpt. 1902-S, 

 1>I>. 1 14-JlS) .—In litOl a fitudy was made of an ontlireak of iio^ cholera at Red Hliiff. 

 Texas fever <-aii.sedc'onsideral)le los.>» to dairyiiieii in Oranjre ("miiity. An iiivestij;ation 

 was made of the (tau.ses of ropy milk and scours in calves. N'etniinnus lironchitis 

 in calves was treated by tlu' administration nf the nsiml remedies hy intratracheal 

 method as well as by inhalation and l)y way of llic moutli. No noticeable results 

 were produced. By an act of the California lejiislature a poultry experiment station 

 has been established at Petaluma and work is beinu carried on at this jdace in the 

 study of poultry diseases. This investij^ation is prosecuted in cooperation with \ . A. 

 Moore. 



Annual report of tlie civil veterinary department, Bengal, 1902-3 {Gil- 

 cutta: Ben(j(tl Si'cntarktt Presn, jip. JS, pi. 1). — Notes are presented on veterinary 

 dispensaries in various parts of Bengal anil on the prevalence and treatment of glan- 

 ders, rinderpest, and other diseases. Brief notes are also given on the condition of 

 the Bengal Veterinary College. 



Report of the chief inspector of stock and brands, C. J. Valentine [RpL 

 Mill. Agr. Soidlt ^{u.^tntlia, 190S, pp. 38-4f')- — Brief notes on ticks, lice, worms, and 

 foot rot in sheep; pleuro- pneumonia, tuberculosis, and actinomycosis in cattle; and 

 various disea.ses of horses, camels, and hogs. 



Generalized tuberculosis in cattle, SciiROEnER {Berlin. Timirzll. WchnsfJir., 

 1908, No. 30, pyp. 471, 47~). — An examination of cases of generalized tuberculosis 

 showed that the meat was in good condition, while the lungs, liver, ])ortions of the 

 ribs, and other structures were extensively affected by the disease. The lymphatic 

 glands and other structures around the joints were so greatly altered that lameness 

 was ]>rodaced as a result. 



The infectiousness of milk of tuberculous cows in the light of recent 

 investigations, Lydia Rabinowitsch [Centbl. Bakt. it. Bar., 1. Aht., Be/., 34 {1903), 

 Nu. 8-9, pp. 2:-!f>-23G) . — A critical review is presented of recent literature relating to 

 this subject. While there is not an entire agreement in the results obtained by 

 different investigators with the milk of tuberculous cows, it is concluded that the 

 investigations thus far made indicate that the milk of such cows may l)e pathogenic 

 for both childi'i'ii and young animals. 



Tuberculosis caused by dead tubercle bacilli, N. Paxov (Dit^xeridtion, Yuriev, 

 1902, pp. 134, pi- 1). — The literature of this subject is critically reviewed in connec- 

 tion with a bibliography. The author's experiments were ma<le on rabbits, and the 

 tubercle bacilli were obtained from consumptive human patients. Ra])bits were 

 inoculated with cultures of dead tubercle bacilli and were later examined for the 

 purpose of studying the histology of "necrotuberculosis." It was found that dead 

 tubercle bacilli contained positively chemotactic toxins which developed other 

 active properties in direct contact with the living cells. These toxins cause the 

 formation of tul)ercles, which at first become necrotic in the center, but later exhibit 

 degeneration and proliferation of connective tissue. When introduced into 

 experimental animals in large quantities dead tubercle bacilli may cause death, 

 and when inoculated by the subcutaneous method they produce suppuration. 



Intestinal tuberculosis in sheep, T. Micucci {(iior. B. >Sor. Arcad. ]'et. Ital., 52 

 {190€), N(j. 35, pp. 817, 818). — On account of the comparative rarity of this disease 

 in sheep, detailed notes are given on a case of intestinal origin in which the liver 

 was enlarged and cirrhotic and infested with flukeworms. The organ was also 

 permeated with tubercles. The lymphatic glands of the liver were hypertrophic 

 and somewhat ilegenerated. The lungs and other al)dominal organs, except the
