trate of potassa, common salt, oil of turpentine). Sponge 

 with, cold water and rub actively till dry. Eub with cam- 

 phorated spirit or oil of turpentine. Give tonics (quinia, 

 salacin, etc.,) antiseptics (mineral acids, nitro-muriatic 

 acid, tincture of the muriate of iron, chlorate of potassa, 

 carbolic acid, bisulphite of soda, tincture of iodine, iodide 

 of potassium, bichromate of potassa). In the Genesee out- 

 break of 1875, I had admirable results from the use of 

 nitro-muriatic acid sixty drops, bichromate of potassa 

 three grs., and chlorate of potassa two drachms, twice daily 

 by the mouth, and two or three drachms of a saturated 

 solution of sulphate of quinia, iodide of potassium and bi- 

 sulphite of soda injected at equal intervals beneath the 

 skin. Of fifty very sick oxen only four died. 



In the advanced and weak conditions stimulants (alco- 

 hol, turpentine, ether, valerian, angelica, camphor, etc.,) 

 are useful. 



Local Treatment. This is very successful with inocu- 

 lated forms of the disease, (malignant pustule, boil-plague, 

 gloss-anthrax, malignant sore-throat) if employed before 

 the poison has passed into the system and produced fever. 

 For these, free cauterization and especially with the anti- 

 septic caustics (crystallized carbolic acid, the mineral acids, 

 chloride of zinc, chloride of iron, sulphate of iron or cop- 

 per) is successful. But the whole diseased tissue must be 

 reached, and in the case of the tongue the bhsters must be 

 first laid open and the agent applied ia small quantity with 

 a brush, or more freely hi a diluted condition. In some 

 external cases the hot iron is used with advantage. Such 

 treatment may still be applied to circumscribed tumors ac- 

 companied by the fever, being followed by poultices to en- 

 courage suppuration. 



For extensive engorgements use astringents (cold water, 

 vinegar, etc.,) weak antiseptic lotions, and, above aU, in- 

 jections with a hypodermic sjTinge of antiseptics (diluted 

 tincture of iodine, diluted carboUc acid — 1-100, etc.) The 

 hypodermic treatment is equally apphcable to the circum-
