of the bluud ami various organs of affected animals and inoculation expennients were 

 conducted on rabbits and jruinea pigs, with the result that all tests proved conclusively 

 that the disease was blackleg. 



Texas fever, J. C. Kobkut {Miftsissippi Sla. Bui. 69, pp. 15, figs. 4). — During tlie 

 l)ast 2 years 65 northern cattle were vaccinated against Texas fever at the station; 

 18 of these were purchased by the station for experimental purposes, and of this 

 number KJ j)assed through the period of inoculation fever and are at present car- 

 rying ticks and in goc<i health. Of the other 47, 20 were vaccinated only once 

 and 27 twice. Of the whole 47, 22 were kept free from ticks until after recovery 

 from the inoculation fever, and none of these died; 25 were subjected to tick infesta- 

 tion before recovery from the fever, and 3 of these died. The nature of Texas fever is 

 briefly described. A record is given of the various symptoms which appear in the 

 inoculated animals. In one case the temperature reached 108° F. Notes are also 

 given on the appearance of various organs as noted in post-mortem examinations. 

 From the author's observations it is concluded that immunity to Texas fever is not 

 transmitted to offspring, that nonimmune cattle of all ages are subject to the disease, 

 and that southern t'attle if prevented from l)ecoming infested witii ticks are equally 

 as susceptible as northern. Blood inoculation is considered the most practical method 

 of conferring immunity. Ijioculated cattle should be kept entirely free from ticks 

 until after recovery from inoculation fever. It is recommended that cattle ticks 

 should not be entirely exterminated on farms south of the quarantine line for Texas 

 fever. It is urged that a few ticks are necessary for the purpose of producing mild 

 forms of the disease and thus immunizing southern cattle. Brief notes are given on 

 the rations which should be fed during periods of fever, and on methods of vacci- 

 nation. 



Actinomycosis, F. Sivoki (Bol. Agr. y (lanaderia, 1 {1901), No. 1, pjp. 21-25). — 

 The author gives a general account of this disease, including statistics on its preva- 

 lence in various countries. In parts of Argentina the disease prevailed in an epizootic 

 form. Ot 9,540 cattle which were examined 8 per cent were found infected with the 

 disease. The different forms of actinomycosis are described according to their char- 

 acteristic symptoms, and treatment with iodid of potash is recommended. 



Operation for neomorphs of actinomycotic nature, C. Dorx {Berlin. Thlenirzll. 

 Wehnschr., 1901, No. :12, pp. 492-494)- — The author gives in detail thesvmptoms and 

 operative procedure adopted in the surgical treatment of actinomycosis in various 

 parts of the bod}'. These operations were made on actinomycotic tumors in the 

 cheek, reproductive organs, nasal passages, eyelids, and bones. 



Pleuro-pneumonia {Agr. Jour. Cape Good Hope, 19 {1901), No. 3, pp. 195, 196). — 

 This disease having become prevalent among cattle in the Transvaal and the Orange 

 River Colony, a proclamation was issued by the government to prevent the impor- 

 tation of cattle from these countries into noninfected regions. 



Milk fever, P. Bridge {Farm and Home, 20 {1901), No. 1000, p. 100).— The term 

 milk fever is considered inappropriate for this disease, on account of the fact that 

 the temperature of affected cows is usually normal, or even subnormal. Preference 

 is given to the term postpartum paralysis. While it is generally recognized that cows 

 which have once had milk fever are very susceptible to the disease at all future ti.-.es 

 of calving, yet it is argued that such animals may be legally declared sound. 



Milk fever, J. C. Robert {Mismsippi Sta. Bid. 11, pp. 6, fig. 1). — A brief account 

 of the cause, symptoms, and treatment of tliis disease. The author recommends the 

 use of Schmidt's treatment. 



Parturient paresis: Schmidt's treatment, W. R. French {Amer. Vel. Rev., 25 

 {1901), No. 5, pp. S56-35S) . — Notes are given on the symptoms, treatment, and 

 results, in 6 cases of this disease, 5 of which recovered under treatment with iodid 

 of potash. In all these cases antiseptic precautions were observed and hourly mas- 

 sage of tlie udder was rigidly enforced.
