338 FRENCH METHOD OF CLEANING SORES. [BK. II. 



out fistulous ulcers, by rolling up pledgets of linen 

 cloth, the edges whereof have been scraped out 

 thin, so that when introduced dry to the bottom of 

 each sinus or pipe, and being twisted round, it brings 

 forth the offensive matter and any residue of blood 

 which may have got into them during the operation. 

 They also employ gentian root to keep down the 

 swelling or thickening of the lips of the sore. The 

 healing is not to be suffered to go on too fast, nor 

 until all the offensive matter has been expulsed, 

 and a more healthy discharge, whilst it manifests the 

 change that has taken place, and warrants your 

 closing the sore. Blue stone spread on any plaster 

 of digestive ointment will effect this ; or take 



Ointment of nitrated quicksilver, 3 ounces, 

 Oil of turpentine, half an ounce. 



Mix, and apply as long as it may be found proper 

 to keep the orifice from closing, to which it will 

 be ever too much disposed. 



Something was formerly said about scraping the 

 bone, whenever the long continuance of the dis- 

 order, its virulence, or the bad state of the horse's 

 general health, hath been such as to affect the fine 

 enamel of its surface ; but this part of the opera- 

 tion is rather showy than useful, as the rottenness 

 so occasioned will come away as the discharge is 

 kept up, there being a constant disposition through- 

 out the whole system to throw off all such offensive 

 matters.
