84 EXPERIMENT STATION RECORD. 



cattle were in this Held from spring until early fall, during* wliich time 

 5 of tbeni died. In October the cattle were turned out into upland 

 pastures where 4 others died. Subsequently 7 other animals perished 

 after an illness of a few days. 



The disease was manifested by a persistent chasing of whatever small 

 animals would come near, accompanied by i)aroxysms of trembling- and 

 weakness. The animals at all times were in an uneasy state, some- 

 times amounting to frenzy, and in the late stages of the disease, after 

 3 or 4 days, paralytic symptoms set in so that the sick animals finally 

 were unable to stand upon their feet. Few lesions were discovered by 

 autopsies, engorgement of the blood vessels, especially in the brain, 

 being the main i^athological conditions noted. Rabies being suspected, 

 although a history of but one mad dog or other animal in several years 

 previous was ascertained, inoculations of brain tissue from animals 

 which had died of the disease were made upon rabbits and calves. All 

 the inoculated rabbits and the greater number of the calves died with 

 unmistakable symptoms of paralytic rabies. Inoculations of other 

 animals from the brains of inoculated animals which had died, pro- 

 duced the disease in every instance. 



The source of the disease is considered as unsettled, although it is 

 thought to be x)ossible that the low, boggy pasture land had much if 

 not all to do with its origin. 



Colic in horses and mules, W. E. A, Wyman {Soufh Carolina Sta. 

 Bui. 22, n. ser., pp. S). — This is a popular bulletin discussing the causes, 

 symptoms, prevention, and general treatment of colic, with additional 

 detailed remarks in regard to spasmodic or crami) colic, flatulent colic, 

 impaction colic, and habitual colic. Moderation in eating and drink- 

 ing and the use of proper food is insisted upon, and in general for 

 treatment are recommended, catheterizing the sick animal, intestinal 

 injections, and the application of a drench of belladonna, hyoscyamus, 

 cannabis indica, and nux vomica, with the addition of some other drugs 

 in some cases. 



Further experience -with tuberculin, J. L. Hills and F. A. Eich 

 {Vermont Sta. Bpt. 1894, pp. 71-74). — j^otes and tabulated data on 

 tuberculin tests made with the new station herd. Forty-one cattle 

 were tested in April and October, 1894, and in June, 1895, uone of 

 them giving reactions sufficient to indicate the presence of tubercu- 

 losis. Two remaining members of the old herd reacted at the October 

 test and were slaughtered. The continued good health of the new 

 herd is regarded as evidence that tuberculin, properly prepared and 

 handled, can not cause tuberculosis. 



A brief note is given on injections made throughout the State. 

 There were inoculated 1,809 cattle in 84 herds, and 234 were found 

 tuberculous. This percentage is not believed to indicate the extent of 

 tuberculosis in the State, for the injections were usually made in herds 

 where there was reason to suspect the existence of the disease.
