 or both, as occaiion may require. Should the 

 difchargc continue iluggifli or incomplete, en-- 

 large the proportion of turpentine or precipi- 

 tate in the ointment, adding an ounce of the 

 fpirit of turpetitincy if the matter is very ofFen- 

 iive ; make alfo a confiderable addition in the 

 tinBure of myrrh and cantharides to the de-

 the applications are required to exert their di- 

 o-eftive powers more effedually, in confequence 

 of any particular languor upon the part, or 

 deficiency in the difcharge, let the ointment 

 be applied with a degree of warmth fufficient

 ings, but not fo hot as to fcald or harden the 

 furface.
