 ^n outbreak in 1875, I had admirable results from the use 

 Qf 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 bisulphite of soda 

 injected at equal intervals beneath the skin. Of fifty very sick 

 oxen only four died. 



In the advanced and weak conditions stimulants (alcohol, 

 turpentine, ether, valerian, angelica, camphor, etc.), are useful. 



Local Treatment. — This is very successful with inoculated 

 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 antiseptic caustics 

 (crystallized carbolic acid, the mineral acids, chloride of zinc, 

 chloride of iron, sulphate of iron or copper) is successful. But 

 the whole diseased tissue must be reached, and in the case of 

 the tongue the blisters must be first laid open and the agent 

 applied in small quantity with a brush, or more freely in a 

 diluted condition. In some external cases the hot fron is 

 used with advantage. Such treatment may still be applied to 

 circumscribed tumours accompanied by the fever, being fol- 

 lowed by poultices to encourage suppuration. 



For extensive engorgements use astringents (cold water, 

 vinegar, etc.), weak antiseptic lotions, and, above all, injections 

 with a hypodermic syringe of antiseptics (diluted tincture of 

 iodine, diluted carbolic acid — i-ioo, etc.) The hypodermic 

 treatment is equally applicable to the circumscribed tumours, 

 but we must saturate their whole substance, otherwise absorp- 

 tion of the poison will lead to general disorder.
