52l< SLOUGHING OFF. [BOOK III. 



Whenever the cankered parts slough off, and 

 leave a more healthy appearance, the powder need 

 no longer be applied at those particular places. 

 Upon these lay on a dressing of tar, in which has 

 been introduced about a tenth part of blue stone, 

 powdered. Let moderate pressure be given to the 

 sole as can be contrived, to prevent the granulation 

 of new flesh coming on too luxuriantly, which is 

 otherwise very likely to happen, on the edges of the 

 wound particularly. In this respect, the grooved 

 shoe will be found effectually serviceable. If, not- 

 withstanding all your care, the edges will grow 

 too fast, touch that part with lunar caustic; and in 

 case the horny substance grows over the still 

 cankered parts, it must be again pared away and 

 laid bare. Perhaps the animal is young and vigo- 

 rous in other respects, and his system probably 

 would promote the secretion of new horn quicker 

 than an older, or less healthy horse ; this difference 

 should teach us to employ some digestive for the 

 dressings, which has less tendency to promote the 

 growth of new horn than tar has, which would be 

 found more proper for old horses. For the younger 

 animals, let turpentine be substituted, into which 

 has been mixed a small portion of the same vitrio- 

 lated copper, (blue stone.) 



From what has been said, the reader will per-

 degree of judgment and discrimination, and that 

 they should not be passed over or delayed, as he 

 values the horse ; for, upon this marked attention
