Epizootic abortion in co\(rs and its prevention, .1. l'ENiii:i;i iiv (.hmr. ('niiij,. 

 j'nlh. ini'l I'lirr., ir, {I'.iO.l), No. 1, pp. lS-10). — Attention is callcil tu tlir uti<>i(.;,'y of 

 tlu' viirions forms of altortion observed in cattle, witli c's|>i'cial n-ferent:e to the epi- 

 zootic form. In comhatin^' tiiis disease the aiitlior considcis it necessary to exercise 

 a close snpeivision npon tiie formation of a lienl, in order HDt to introduce any 

 infected animals. Treatment of al)ortinf^ cows is somewhat unsatisfactory. 



Contagious abortion in cows, J. I\I. P\)NT.\n {Jour. Agr'icolc [/'rrr/.s], 14, [lUO-i), 

 An. i6V7, pp. J13-J15). — The syini)tonis and patlioloj^ncal anatomy of this disease are 

 brii'tly described. In the proj)hylaxis of conta^dons abortion the author recom- 

 mends the exercise of special care in introducing new animals into the lierd and tlie 

 thorough ai)plication of an anti.sei)tic, such as corrosive su))limate, after the appear- 

 ance of abortion. 



Mammary actinomycosis in cows, J. Kow.\lewsky [Jour. Mai. VH. cl Zoolecli., 

 5. tier., 7 {1903), Sq)l., pp. 513-520). — Mammary actinomycosis occurs most frequently 

 in ])igs and rarely in cattle. A tal)le is presented showing the relative freipiency 

 with which various organs of cattle are affected by actinomycosis. The author had 

 occasion to examine 3 cases of manunary actinomycosis in cattle and detailed notes 

 are given on the pathological anatomy. Notes are given t(j assist in differential tliag- 

 nosis between actinomycosis and vari(jus forms of mannnitis. Jn diagnosing this 

 disease the author believes the best results are obtained from a microscopic study of 

 the milk. 



Actinomycosis, V. E. Mkktens {Zlachr. II[/ij. u. liifcdioii^kndik., 4J {1903), Xo. 1, 

 pp. 45-S9, ph. 2). — A study was made of the behavior of actinomyces on various 

 culture media, and results thus obtained are compared with the published results of 

 other investigators of this subject. During the author's investigati<jns special atten- 

 tion was given to determining the cause of the formation of club-shaped structures in 

 the mycelia of actinomyces. It is concluded from these investigations that the club- 

 shaped structures are produced ])y the living mycelia as the result of degenerative 

 })rocesses which may affect whole liyphic or only certain parts of them. A nund)er of 

 inoculation experiments were made in rabbits and notes are given on the course of 

 the disease and the forms of actinomyces obtained from such cases. 



Actinomycosis in dog-s, L. Bahr {Maanahskr. DyrUrger, 15 {1903), No. il, pp. 

 172-196, jicjs. 4)- — Detailed notes are given on the pathological anatomy of this disease 

 in a number of cases in dogs. The source of infection is discussed and the peculiari- 

 ties of the disease as related to the organism of dogs are mentioned. Actinomycosis 

 may appear in dogs in the form of tumors, idcers, or chronic fistulous jjrocesses, and 

 freijuently leads to jileuritis or ])eritonitis. Ajjparently there are several species of 

 ai'tinomyces concerned in the production of the disease in dogs. 



Six cases of carcinoma of the ox, A. M. Tkottek {.four. Coinp. I'nili. attd liter., 

 lij {1903), No. 3, pp. 244~252,pl. l,fi<js. 2). — Detailed clinical and post-mortem notes 

 are given on cases of carcinoma of the orbit, rumen, and lung in cattle. The forms 

 of carcinoma described in this paper are epitheliomatous, and the form characterized 

 by spheroidal cells. 



Hypoderma bovis, T. P. Koch {Mannedxiikr. Di/rluyer, 15 {1903), No. 5, pp. 

 129-159). — The life history of this insect is descril)ed in great detail in connection 

 with a critical review of the literature relating to the subject. 



Pathological changes in the esophagus due to the larvae of warble flies, 

 C. O. Jensen {MaanedHnkr. JJyrhvger, 15 {1903), No. 6, pp. 109-171). — Certain patho- 

 logical conditions are noted in the esophagus of cattle infested with warble flies. The 

 author investigated the cause of these conditions with the result that the warble fly 

 larva' w'ere found to be apparently responsible for the production of infiltration pro- 

 cesses in the esophagus. 



Serum therapy in sheep pox, A. Bokkel {Ann. Inst. I\istevr, 17 {1903), N'o. 11, 

 pp. 732-702). — A detailed description is presented of the course of sheejj pox, the
