Subcutaneous injections, F. Eschbaum {Berlin. Tieriirztl. Wchnschr., 1900, Xo. 4, 

 pp. 39-41) ■ — The author l^elieves that the hypodermic injection syringe should be 

 constructed with 2 or 3 rulings measured with special care, in order that the size of 

 the dose may be accurately known. It is necessary to take into account the siiecific 

 weight of the substances which are to be used in these syringes. The author recom-

 and an account of tuberculin tests in suspected cases. 



Failures in the diagnosis by means of tuberculin, S wicker (Berlin Tifri'irztl. 

 Wclinsehr., 1900, No. 5, pp. 5.2-54)- — Tlie author l)elieves that a considerable propor- 

 tion of the causes of alleged failure of tuberculin is due to simple carelessness in 

 labeling the animals during the tuberculin test. Where the test is applied simul- 

 taneously to a large number of cattle, the greatest care must be exercised to prevent 

 mistakes in the identity of the records before and after injection. 



Letters relating- to the distribution of vaccine ( T'. S. Dept. Agr., Bureau of Ani- 

 mal Indufitry Circ. '28, pp. 9). — This circular contains a copy of a letter of the Secre-

 letter, and a letter from the H. K. Mulford Company to the Secretaiy of Agriculture, 

 together with a reply to the same. These letters have to do with the question of the

Pseudoscabies, A. W. Bittixg {Indiana Sta. Rpt. 1899, pp. 43, .^^).— Upon inves- 

 tigating an allege<l outbreak of sheep scab, it was found that the trouble was due to 

 the awns of Siij^a uparlea. These awns had evidently penetrated the skin of the sheep 

 in the Southwestern States, from which they had been imported. 



The so-called air-bladder mesentery of swine, Sch.mutzek {Ztsclir. Fleiscli u. 

 Milchhiig. , 10 { 1900) , No. 5, pp. 89-95) . — The author discusses the Avell-known ajjpear- 

 ance of small air bladders in the mesentery, especially of the small intestine in healthy 

 pigs. From a careful study of a large number of cases, the author concludes that the 

 gas contained in these bladders is not the jiroduet of micro-organisms and does not 

 come from tlie intestine, but that it comes from the outside air. 



Glanders and the sanitary law, O. Lebrun {Rec. Med. Yet. Paris, 8. .svr. , 7 (1900), 

 No. 1, pp. 32, 33). 



The diagnostic value of mallein, E. Isepponi {Schweiz. Arch. Thierh., 42 (1900), 

 No. 1, 2)p- 1-20). — In a drove of 60 horses, 2 were suspected of having glanders, and 

 mallein tests were given to these horses. The post-mortem examinations in these 

 two cases furnished confirmation of the reaction which was obtained by the use of 

 mallein. Mallein tests were made upon a number of other horses, and the details of 

 the temperature conditions are given. 



The author concludes that glanders often exists in a hidden form and tliat, there- 

 fore, mallein is a necessary agent in the eradication of the disease from a drove of 

 horses. It is recommended that mallein tests be given at once to suspected horses, 

 and that such as fail to react should be at once removed from quarantine. 



The reliability of the Strauss method, C. Tro ester {Zfschr. Yeterinurk., 12 

 {1900), No. 2, pip. 69, 70). — As a result of considerable experience in diagnosing

 male guinea pigs is jierhaps the most reliable one for making correct diagnoses.
