Similar negative resnlts were obtained by Miiller with the milli of 9 cows, 

 Asc'her with the millv of 7 cows, and Stenstnim from 50 cases. Tlio author con- 

 cludes that the milk of cows that merely react to tuberculin but do not show 

 clinical symptoms of (he disease does not contain tubercle bacilli. The proper 

 means of preventinsi the infection of milk with tubercle bacilli is to eliminate all 

 rasi's of nianiniaiy tuhen-ulosis and other clinical cases. 



Tubercle bacilli in the milk of tuberculous cows, D. A. de Jong {Ccntbl. 

 liakt. [etc.], 1. Alt., Orlg., J/G UDOH), Ao. d, pp. 2/3-2/?).— Many investigators 

 have worketl on the problem of determining whether it is possible to fix a limit 

 in the progress of tuberculosis beyond which the milk becomes dangerous. The 

 author considers it desirable to secure fresh evidence pn this point. Of the 11 

 cows ui)on which he made experiments. 1 showed clinical symptoms of tuber- 

 culosis, wliile in the other 10 the disease could not be diagnosed except by the 

 u.se of tuberculin, yet in 3 of the 10 reacting cows the milk contained virulent 

 tubercle bacilli. The conclusion is therefore drawn that in order to be ou the 

 safe side it is necessary to exclude the milk of all tuberculous cattle. 



The frequency of tubercle bacilli in the market milk of the city of Wash- 

 ington, D. C, J. F. Andkkson (Jour. Infect. Discu.sci, J (1!)0S), No. 2, pp. 107-

Combating' tuberculosis by control of dairy by-products, 11. Martel (Induft. 

 Lnit. \l'<nis\, .j.i ( I'.ios), Xo. !). pp. 13'>-l'i't) . — Statisius are presented showing 

 the i)ercentage of tuberculosis among hogs and other animals which are fed 

 on dairy by-products with or without previous sterilization. The importance 

 of sterilizing such by-products is clearly indicated by these statistics. It is 

 reconimendeil that all dairy by-products be sterilized before being used. 



Chronic pseudotuberculous enteritis in cattle, Bugge and W. Albien {Ber- 

 lin. TUriirztl. Wchnsclir., 1908, A'o. 10, p. 175). — The author's report that in a 

 study of chronic enteritis of cattle they have at last isolated pseudotuberde 

 bacilli and have shown that the disease is not a form of tuberculosis. A fur- 

 ther study will be made of the subject as a liasis for a more complete rei)ort. 



Chronic bronchitis and broncho-pneumonia in cattle, L. Keisincikr 

 (Monatsh. I'm Id. TkrhvUk., /.'/ (lUOS), A o. .'j-G, pp. 11)3-225, pgs. 3) .—liiicillus 

 pyogrnrs apjiears to become associated secondarily with this disease or be- 

 comes more virulent when the mucous nieml)rane of the bronchi is affected in- 

 juriously by irritants of various sorts. While B. pyogenes is to be considered 

 as a secondary rather than a primary cause of the disease it nevertheless pro- 

 duces during its development specific tissue changes by which the disease is 

 cliaracttTized. 



The Koopmansfontein lamziekte experiment, J. Spreull (Agr. Jour. Cape 

 (iood Hope, 32 {WOH), A'o. 3, pp. 289-300, figs. 6).— Cattle selectetl for experi- 

 mental puriKtses were divided into a number of different lots which received 

 different treatment for the puriwse of determining the effects of such treat- 

 ments ui>on the development of lamziekte. Some of the cattle were given 

 access to a salt lick, others receivcnl bone meal, and still others tar or ashes. 

 The disease is believed by the author to be of a bacterial nature, but the use of 

 bone meal is of great benefit in preventing itw develoi)ment. 



A practical method of determining the dose of serum required to pro- 

 tect contact animals in outbreaks of rinderpest, (J. K. Wai.kkr {Jour. Trop. 

 Vet. Hci., 3 ilUOH), No. 1, pp. 28-32).— It usually requires much tact on the 

 part of veteriiuiry (tflicers to put in operation any system of vaccination against 

 rinderpest among cattle belonging to ignorant natives. Some exjterinjents have
