methods used for their detection. The results of a feeding test with a horse and 

 calf are also given. 



Report in reg'ard to the activities of the health department of the chamber 

 of agriculture in the Province of Pomerania, 1909-10, Sciimitt {A bs. in CcntM. 

 Bakt. [etc.], 1. Abt., h'cf., J,'.) (1911), Xo. ',, p. 12!)).— In tlie work in regard 

 to bovine tuberculosis 300 barns containing 20,155 animals over 6 months old 

 were examined for clinical and open tubex'culosis. For the bacteriological tests 

 512 samples of milk, 36 samples of nasal secretion, 13 samples of vaginal and 

 uterine secretions, 1 piece of mucus tissue from the vagina, 2 pieces of lymph 

 gland from the udder, and 2 samples of feces were received. 



Open tuberculosis was detected in 36 bovines by clinical measures and in 

 78 by bacteriological tests. It was distributed as follows: Out of 925 bulls 

 (breeding) none were affected; of 16,183 cows 110, or 0.68 per cent; of 8.897 

 young bovines 3, or 0.03 per cent ; and of 150 draying cattle and cattle reserved 

 for fattening 1, or 0.67 per cent. Of these 114 diseased animals 56 had tubercu- 

 losis of the mammary gland, 56 tuberculosis of the lung, and 2 tuberculosis of 

 the uterus or vagina. 



For combating hemoglobinuria of bovines, the vaccine prepared at this insti- 

 tution was utilized, and among 4,456 animals the protective vaccination re- 

 duced the mortality and the disease to a very large extent. 



In regard to the disinfection of goats' hides and hair, H. A. Gins (Desin- 

 fektion, 3 (1910), No. 8, pp. 40 5-.', 07 ; qbs. in Ccntbl. Bakt. [etc.], 1. Abt., 

 Ref., Jf8 (1911), No. 18, p. 567). — It was possible to destroy anthrax spores 

 in hides and hair with a formaldehyde steam mixture at 60° C. under a dimin- 

 ished pressure (160 mm. of mercury) in Rubner's apparatus. The hides, 

 however, were also destroyed by the process, although the bristles were not. 



Sero-diagnosis of glanders, F. K. Meyer (Amer. Vet. Rev., 39 {1911), Nos. 

 2, pp. 176-188, figs. 2; 3, pp. 261-269).— This is a discussion of the agglutination 

 test, deviation of complement test, precipitation test, and sero-anaphylactic test, 

 with particular reference to the value and technique of the complement-binding 

 or deviation test for glanders in animals (E. S. R., 25, p. 181). 



Interpreting the mallein reaction, W. N. Matwejeff (Abs. in Ztschr. Immu- 

 nitdtsf. u. Expt. Ther., II, Ref., 3 (1910), No. 9, p. 889). — In a paper read before 

 the Second Veterinary Congress at Moscow, 1910, the author, after discussing 

 the numerous practical rules for conducting this test, points out the necessity 

 of taking the temperature at least 4 hours before introducing the mallein, and 

 then determining the temperature hourly, beginning at the seventh hour after 

 the injection and continuing it the 7 succeeding hours. 



The mallein is best introduced in the forebreast because of the fact that this 

 region is a favorable anatomical one for observing the swelling which takes place. 

 The characteristics of the typical swelling, which has a definite line of de- 

 marcation, are a very pronounced, hard, painful area which is very warm to 

 the touch. The size is usually 15 by 15 cm. In normal horses a local swelling 

 also takes place when mallein is injected, but it is not so large as that in the 

 glandered animals. 



The author points out that the focal reaction, in the sense of an exacerbation 

 must not be overlooked, in interpreting the mallein reaction. If a doubtful 

 result is obtained, the author recommends a second injection of mallein, but 

 only after one month has elapsed. 



Hog cholera in man, F. Erben (Miinchen. Med. Wchnschr., 58 (1911), No. 

 6, p. 299). — The author reports the symptoms of a condition which was pro- 

 duced in 5 individuals (2 adults and 3 children) by the ingestion of the viscera 

 obtained from 2 hogs suffering from hog cholera.
