imd often presents vesicles on its surface. After a iev/ 

 days the 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 httle tendency to heal. When mat- 

 ter forms it is liable to be diffused without any hmiting 

 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 jdus and its deposit in 

 internal organs, with fatal results. 



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

 and hind hmbs, and is especially liable to prove oedema- 

 tous. It is distinguished from Anthrax and Purpura 

 Hcernorrhagica by the presence of the wound or sore, by 

 the low inflammatory character of the swelling, 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 mainly about the head, 

 but often and more severely about the iidder, belly and 

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



Sioine are mainly attacked about the head and neck, 

 and less frequently on the inner side of the hmbs, the 

 chest or belly. 



Treatment. Open the bowels freely (horse, ox and 

 sheep, Glauber salts ; swine and dog, castor-oU,) following 

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

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

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

 cohoHo or ammoniacal as they may be demanded, but 

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

 Diuretics may be used in oedematous cases, but in a 

 guarded manner because of the depression. To the af- 

 fected skin apply warm fomentations, by preference, with 

 weak solutions of tincture of muriate of iron, hyposulphite 

 of soda or sulphate of zinc. Sometimes dry applications 

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