Some points in the history of the determination of pulmonary tubercu- 

 losis from alimentary infection, A. Chauveau {Rev. Gen. Med. Y6t.. i) {1907). 

 i\(). to'). PI). Ji91-iJl()). — \ brief resume is given of the worlv of the author and 

 otluT investigators in which evidence is offered that a considerable percentage at 

 least of the cases of ])ulnionary tuberculosis arise from infection througli the 

 alimentary tract. 



The intestinal origin of pulmonary tuberculosis, (iAUTiEK {Bid. Hoe. Cent. 

 Med. Vet.. HJ, {WOl), JSo. S, pp. 190, 200). — Attention is called to Yallee's con- 

 firmation of von Behring's hypothesis that a large percentage of the cases of 

 pulmonary tuberculosis in animals arise from a primarj^ infection in the ali- 

 mentary tract. Such has been found to be the case in numerous instances. The 

 alimentary tract may show no lesions at the i)oint where the bacilli entered, hut 

 frequent involvement of the mesenteric glands is believed by the author to add 

 weight to tlie tlieory. 



Tuberculosis of the myocardium, W. Vanderburg {Tijdsehr. Yeerurtsenijk., 

 o'l {1907), No. 7, pp. Ji3.'f-Jf39) . — It is of comparatively rare occurrence that the 

 muscle of the heart is iuvolved in cases of tuberculosi>s. Brief notes are given on 

 cases of this sort in cattle and horses. 



The role of alcohol in bovine tuberculosis, Spartz {Bui. Hoe. Cent. MM. 

 Vet., 8Ji {1907), No. s, pp. 1S9, 190). — Recent experiments have shown almost 

 uniformly that the use of alcohol favors the development of tuberculosis. For 

 obvious reasons this matter has been studied most extensively in man. The 

 autlior's observations, however, indicate that cows which receive distillery by- 

 products are more susceptible to tuberculosis and are infected in a larger per- 

 centage of cases than cattle which do not have these by-products in the ration. 

 In a number of instances herds of cows fed on such products were found to be 

 tuberculous to the extent of 90 to 100 per cent. 



The condition of the leucocytes in the presence of encapsuled anthrax 

 bacilli, T. Stiennon {Compt. Rend. Hoe. Biol. [Paris], 62 {1907), No. 13, pp. 

 6.'fG, 6'.p'). — The author's experiments were made on guinea pigs. It appeal's 

 that anthrax bacilli in capsules are. very resistant, and even after being sub- 

 jected to a temperature of (iO° C. for half an hour they are not destroyed by 

 the phagocytes in the peritoneum. Apparently the presence of the capsule pro- 

 tects them from the action of the phagocytes and the exudate in the i)eritoneum. 



Proceedings of a conference of Federal and State representatives to con- 

 sider plans for the eradication of the cattle tick (['. *S'. Dept. A</r.. Bur. Anim. 

 Indus. Bill. 97, pp. 98). — A confere'ice was held in Nashville, Tenn., December 

 5 and 0, 190G, at which representatives of the Bureau of Animal Industry and. 

 State authorities interested in the extermination of cattle ticks took part. At 

 this conference the attitude of the Bureau of Animal Industry to\A'ard the sub- 

 ject was outlined l)y A. D. Melvin, and notes on the cooperative work thus far 

 carried oil \^ere presented by 11. I'. Steddom. Such work has been done in 

 nearly all of the Southern States. During the first year of cooperative effort 

 about 549,000 head of cattle have been inspected, and an area of 50,000 sq. 

 miles, covering 45 whole counties and pax'ts of 13 other counties, has been appar- 

 ently freed from ticks and released from quarantine. These results encourage 

 the belief that with an annual appropriation of ^250,000 the cattle tick can be 

 ultimately eradicated. 



The legal side of the question was discussed by G. P. McCabe and recommen- 

 dations made regarding the phraseology of laws intended to permit cooperation 

 between Federal and State authorities. This matter was also referred to by 

 D. F. Luckey. The difRailties met with in the enforcement of quarantine regula- 

 tions were mentioned by T. Mori-is, and C. A. Cary called attention to the desira-
