166 ULCERS. 



filled with a pledget of lint, well impregnat- 

 ed with warm digestive, and plentifully co- 

 vered with tow spread with the same. After 

 a second or third dressing, should the inside of 

 such cavity prove callous, or hard in sub- 

 ^taiiCe, it must be taken away by the knife^ 

 or destroyed by the means before described. 

 If it be so situated that the parts forbid an 

 entire separation, sound with the probe, and 

 at its extremity make a counter incision 

 through the integuments to meet the probe, 

 till by passing through, it removes any lodg- 

 ment that may haye been left for the matter 

 to corrode, which it will very soon do, so as 

 in many cases to affect the bone itself. 



As a very good detergf:nt wash for the 

 cleansing inveterate ulcers, or injecting into 

 such passages as from the disposition of the 

 parts cannot be laid open, I have reason tq 

 recommend the following, it retaining every 

 advantage, without one of the prejudicial 

 qualities so predominant in the mercurial and 

 yitriolic compo'sitions : 



Taile honey and vinegRr each two ounces ; 

 Xiiquefy oyer the fire ; and when cool, add tincture 

 of myrrh and tincture of cantharides each on^ 

 ounce. — Mix.
