morteui examination, a tumor is found surrounded by a sort of fibrous membrane. 

 The tumor is of a grayish or brownish color, and after Ijeing sectioned is found to 

 contain minute yellow granular colonies of actinomyces. 



The unsolved problems of milk fever, J. M. W. Kitchen {Jour. Comp. Med. 

 and Vet. Arch., 2.3 {1902), No. 4, PP- 2S0-2S4) -—The various doubtful problems con- 

 cerning the etiology of this disease are discussed by the author, in connection with 

 detailed notes on a case in which the iodid of potash treatment was used in connec- 

 tion with other remedies. 



An enzootic attack of chorea among cattle, A. D. Knowles {Jour. Comp. 

 Med. and Vet. Arch., 23 {1902), No. 1, pp. 37-40). — The author reports the occurrence 

 of symptoms of chorea among cattle after being allowed to fatten upon a 40-acre field 

 which was fenced in during the summer and not grazed until fall. The symptoms 

 appeared for 2 or 3 years in succession, and at times became quite serious, but did 

 not result fatally except in one case where the animal fell into a ditch of water in one 

 of its fits and was thoroughly chilled. The etiology of these outbreaks is not 

 explained. It was possibly due to eating poisonous plants. 



Poisoning- by feeding on Sinapis nigra, F. J. Rous {Jour. Comp. Med. and 

 Vet. Arcli., 23 {1902), No. 4, pp. 24^-244)-— ^oten are given on a case of poisoning 

 from eating this plant during which 11 cows died and 7 others were badly affected. 

 The cows had been allowed to eat large quantities of the mustard and were affected 

 with a rather uniform set of symptoms, including coldness of the extremities, diffi- 

 cult respiration, dullness of the sensorium, and more or less difficult locomotion. 

 Some of the cows staggered and occasionally fell. Seven of the cows were treated 

 with sulphate of soda, in li-lb. doses, together with nux vomica and spirits of niter. 

 All of them recovered from the effects of the poison. 



Foot-and-mouth disease, with an account of the outbreak in Suffolk dur- 

 ing 1901, E. J. Cheney {Agr. Sttidents' Gaz., n. ser., 10 {1902), No. 5, pp. 135-140).— 

 Notes are given on the symptoms of this disease and its infectiousness for different 

 species of domesticated animals. An account is also presented of a number of out- 

 breaks which occurred in Suffolk during 1901. The probable origin of these out- 

 breaks is discussed with a view to devising means for preventing similar outlireaks 

 in the future. 



The ineffectiveness of Baccelli's method for treating foot-and-mouth dis- 

 ease, M. Strebel {Schweiz. Arch. Tierh., 44 {1902), No. 2, pp. 72-76).— The author 

 gives a critical review of the literature of this subject, from which it appears that 

 many investigators have tested the effect of intravenous injections of corrosive sub- 

 limate in treating foot-and-mouth disease, without good results. 



Corrosive sublimate, the newest remedy for foot-and-mouth disease, M. 

 Strebel {Schweiz. Arch. Tierh., 44 {1902), No. 1, pp. 19-26).— The treatment of foot- 

 and-mouth disease by intravenous injections of corrosive sublimate, as recommended 

 by Baccelli, has not given good results in the hands cf other investigators. The 

 author conducted a number of experiments in making intravenous injections in ani- 

 mals affected with foot-and-mouth disease, and found that the action ascribed to 

 corrosive sublimate by Baccelli did not lake jjlace. In 3 animals a considerable 

 increase of temperature was produced; in 3 others the temperature was unaffected; 

 while in another 3 the temperature was slightly lowered. No curative effect was 

 observed. The treatment was applied from 6 to 8 days after the appearance of the 

 disease. 



Pustulous dermatitis of cattle, E. Lienaux {Ann. Med. Vet., 51 {1902), No. 5, jyp. 

 237-245). — A description is given of a malignant form of dermatitis, with the forma- 

 tion of pustules and with fatal result in one case. In this case attempt was made to 

 treat the pustules with antiseptic washes, but without result. The cause of death in 

 this case does not appear very clear, without assuming septicemic infection. The
