and often presents vesicles on its surface. After a few 

 days tlie swelling and redness may diminish, and the 

 blisters dry up into scales, which drop off, leaving a dark, 

 red, tender surface ; or cracks may form with a sluggish, 

 unhealthy action and little tendency to heal. "When mat- 

 ter forms it is liable to be diffused without any h'miting 

 membrane as in an ordinary abscess, and to lead to exten- 

 sive death and sloughing of the skin and subjacent 

 structures, or to absorption of pus and its deposit in 

 internal organs, with fatal results. 



In horses it is seen mainly about the head, chest, beUy 

 and hind Hmbs, and is especially liable to prove cedema- 

 tous. It is distinguished from Anthrax and Purpura 

 Hcemorrhagica by the presence of the wound or sore, by 

 the low inflammatory character of the sweUiag, by the 

 greater tendency to suppuration, and the impHcation 

 of the adjacent lymphatic glands. 



Cattle suffer especially about the head but also on other 

 parts of the body. Sheep suffer maioly about the head; 

 but often and more severely about the udder, belly and 

 inner side of the thigh or arm, and it may be elsewhere

 chest or belly. 



Treatment. Open the bowels freely (horse, ox and 

 sheep, Glauber salts ; swine and dog, castor-oil,) foUowiag 

 it up by frequent and fuU doses of tincture of muriate of 

 iron and a nourishing, easily digested diet. In case of 

 much weakness or with very low ifever use stimulants, al- 

 coholic or ammoniacal as they may be demanded, but 

 never if they cause dryness of skin and rise of temperature. 

 Diuretics may be used in cedematous cases, but in a 

 guarded manner because of the depression. To the af- 

 fected skia apply warm fomentations, by preference, with 

 weak solutions of tincture of muriate of iron, hyposulphite 

 VI soda or sulphate of zinc. Sometimes dry applications 

 have a good effect, — as a mixture of sulphate of ziac and
