THRUSH. — OANKEB. 519 



removed every portion of ragged, horny matter, toucli the parts 

 exposed with a feather, previously dipped in Nitric Acid. 

 Dress freely with Balsam of Sulphur, made close to the foot 

 by a packing of soft tow, the whole should then be firmly 

 secured to the sole by means of the shoe and a leather covering. 

 Sulphate op Coppee. — Sometimes Balsam of Sulphur 

 fails to cure the disease. When such is the case, resort to the 

 Sulphate of Copper, which may be applied mixed with treacle ; 

 use it in the manner as directed to use the Balsam of Sulphur. 

 "When the malady is obliterated, continue, for some time after- 

 wards, the use of leather soles to the feet. 



Tbeatmekt or Cankee. — In commencing the treatment 

 of Canker, the first essential is to freely expose every part of 

 the sole which may be diseased. So long as any portion of 

 diseased tissue remains unexposed, every eff'ort to cure Canker 

 will prove abortive. The most difficult parts to explore, when 

 afiected, are the comers of the heels, and between the laminse 

 and the crust ; in fact, when the disease spreads to the laminse 

 in front of the foot, the case may be considered as all but 

 incurable. The best remedies and modes of treatment, in 

 general, are — Poultices, Chlorate of Potass, Balsam of Sulphur, 

 Nitric Acid, Sulphur, Liniment Eruginis, and pressure to the 

 sole. 



Poultices. — Chloeate or Potass. — Poultice the feet as 

 directed for Thrush ; and, as the horn becomes softened, remove 

 it with the drawing-knife, until every portion of diseased struc- 

 ture is fully exposed ; after which, discard the yeast, and mix 

 the bran and coarse flour with hot water, in which has been 

 previously dissolved about 2 or 3 drachms of Chlorate of 

 Potass. Poultices of this kind may be occasionally applied to 

 the feet for several days in succession : continue them, in fact.
