VETERINARY SCIENCE AND PRACTICE. 



Observations on the experiment cows with reference to tuber- 

 culosis,'!. Nelson {New Jersey Stas. Bpt. 1897, pp. 224-240). — This por- 

 tion of the author's report consists of a description of autopsies and of 

 temperature tests. 



"The members of the experiment herd have now been injected with tuberculin 

 from 15 to 17 times within 3 or 4 years. In general, the results agree with the con- 

 clusions published in previous reports. Repeated injection of tuberculin does not 

 seem to exert any decided influence, either for increase or for cure of tuberculosis of 

 slightly tuberculous animals. The results in some cases appear to point in one direc- 

 tion and in others in the opposite direction, but in neither case so decidedly as to be 

 of practical import. In some cows the reaction which tuberculin causes is entirely 

 suppressed by repetition of in jection, and in others it is only temporarily suppressed." 



Cornstalk disease, A. T. Peters {Nebraska Sta.Bul. 52, pp. 51-62). — 

 The cornstalk disease of cattle and horses is described and the various 

 theories which have been advanced as to its cause are discussed, the 

 opinions of many investigators being quoted. Circulars requesting 

 information concerning the prevalence of cornstalk disease in Nebraska 

 were sent out, aud the replies received are summarized. 



"From the data- gathered from these few letters and from past experience it is 

 known that a great many cattle succumb to this disease. These further show that 

 there is a great difference in the time that animals are in the fields before the first 

 death occurs. It is also clearly shown that the stockmen have found a remedy in 

 feeding a grain ration and not allowing stock to feed on cornstalks alone." 



The prevalence, symptoms, and treatment of milk fever, garget, 

 and abortion, J. Nelson {New Jersey Stas. Rpt. 1897, pp. 241-260). — 

 The occurrence of milk fever and abortion in the college herd led the 

 author to study these diseases and garget. A circular letter was sent 

 to numerous localities iu the State requesting information on the preva- 

 lence of these diseases in dairy herds and concerning the remedies 

 employed, including the use of disinfectants. 



Replies indicate that 64 herds were affected with milk fever, 70 with 

 garget, and over 90 with abortion. In 25 of the herds abortion had 

 prevailed to an extent ranging from L'O to 100 per cent. The symptoms, 

 cause, and treatment of milk fever and garget are described. The 

 reports received indicate that about 150 cows were affected with the 

 former disease and that the majority died. During the past 4 years 

 this disease has become less prevalent than formerly. 



About 150 cases of garget are reported. Bovine abortion is discussed
