Ohio and in the appUcation of the tuberculin test. Attention is called to the desir- 

 ability of reasonable, effective, and uniform legislation for controlling this disease. 



Tuberculosis in the suprarenal glands in cattle, A. ^I. Bergman {ArcJt. 

 TT7.S.S. *(. Frakt. Thierh., 28 {1902), Kd. 5, pp. 496-.504) .—In the author's opinion 

 tuberculosis affects the suprarenal glands with considerable frequency. In all 21 

 cases were investigated, among which 1 gland was affected in 9 cases and both 

 glands in the other 12. The suprarenal glands are also affected with tuberculosis 

 in the case of hogs. The disease in this situation is of a chronic nature with pro- 

 nounced tendency to the formation of calcareous deposits in the pathological foci. 



Statistics on tuberculosis in bogs, N. Zelenin {ArcJi. Vet. Nauk, St. Petersburg, 

 32 {1902), No. 8, pp. G9.3-727). — Detailed statistical notes are given on the extent of 

 tuberculosis in the various parts of Russia. Among 178,520 hogs examined during 

 the years 1895-1899, tuberculosis was found in 5,679, or 3.2 per cent. As a result of 

 further extensive compilation of statistics it was found that from 7.6 to 12.9 per cent 

 of hogs were condemned on account of infection with tuberculosis. 



Tuberculosis of the udder in a mare, C. Parascandolo and V. de Meis {Arch. 

 T17.S.S. u. Prakt. Thierh., 29 {1903), Xo. 1-2, pp. 198-208).— The literature of mam- 

 mary tuberculosis is briefly reviewed and detailed notes are given on a case of 

 mammary tuberculosis in a mare. The case is considered to be rather important on 

 account of the relative infrequency of the disease in horses. 



Tuberculin, H. F. Palmer {Jour. Comp. Med. and Vet. Arch., 23 {1902), No. 7, 

 pj). 410-416). — Notes are given on the nature of tuberculin, its reliability as a test 

 for tuberculosis, and the method of making the test with it. A brief account is also 

 presented of the nature, use, and effectiveness of mallein. 



Actinomycosis of cat.le, I. I. Shukevich {Uchen. Zapiski Kazan. Vet. Inst., 19 

 {1902), Xos. 3, pp. 193-230; 4, pp. 231-335).— In this article the author presents an 

 exhaustive discussion of the sj'mptoms of actinomycosis, the morphology of the 

 actinomycotic tumors, the differential diagnosis between actinomycosis and pseudo- 

 actinomycosis due to Streptothrix and also bacterial pseudo-actinomycosis. The 

 biology of various forms of actinomyces is discussed in detail, with numerous ref- 

 erences to the literature of the subject. Actinomyces is divided into 3 groups 

 according to differences in morphology and biology. The jsathological histology and 

 pathogenesis of different forms of actinomycoses are also discussed in great detail. 



Actinomycosis from a bacteriological standpoint, W. Silberschmidt ( Compt. 

 Pend. 10. Cong. Internut. Ilyg. et Daiiogr., I'aris, 1900, pp. 90, 91). — The author's 

 conclusions from his study of this disease are as follows: Actinomycosis is not a 

 simple disease of uniform etiology in all cases. The organisms isolated by Wolff, 

 Israel, and Bostrann are not always found in cases of the disease. The organisms 

 of actinomycosis belong to the Streptothrix group and show many points of i-esem- 

 blance to the tubercle bacillus. 



Experimental researches on the variability of Bacillus anthracis, H. Mar- 

 TEL {Pecherches expernnentales sur la variabilile da Parll/us anthraci.^. Paris: C. Natid, 

 1902, pp. 85, pi. 1). — An extensive series of experiments was conducted for the pur- 

 pose of determining the influence of different conditions of environment upon the 

 morphology and biology of the anthrax bacillus. As a result of these experiments it 

 was found that anthrax bacillus exhibits a number of variations, either spontaneously 

 or under the influence of artificial manipulation. The filamentous form of the organ- 

 ism, which is the normal form of the bacillus, when cultivated in a liquid nutrient 

 medium may be changed into straight short rods when inoculated into dogs. Several 

 passages through this animal results in a short bacillus capable of rei^roducing by 

 fission and sporulation. This morphological variation of the organism is difficult to 

 maintain. It is only necessary to pass the organism through very sensitive animals, 

 such as young cats and guinea pigs, or to cultivate it on potatoes or agar-agar in order 

 to obtain the original form. The functional variations of the anthrax bacillus are
