attacked by it. The following ointment has been, 

 found an excellent remedy : 



Strong mercurial ointment . 6 pounds, 

 Spirit of turpentine ... 3 gills, 

 Hogs' lard, tallow, or butter . 6 pounds. 



The hogs lard, or butter, must be first melted, and 

 poured over into a vessel ; then add the mercurial 

 ointment, stirring them well together until properly 

 incorporated, and all cloudiness disappears, when the 

 mixture will be of a uniform pale grey colour. The 

 turpentine must then be added, and the whole stirred 

 together until the ointment is thoroughly mixed, and 

 then pour it into a large flat dish, that it may cool 

 rapidly, so that the mercury may not sink to the 

 bottom, to prevent which the mixture should be stirred 

 until cold. 



The following preparation has also been found 

 effectual, and is considerably cheaper than the pre- 

 ceding : 



Corrosive sublimate, finely powdered 8 ounces, 



Train oil 6 gallons, 



Resin 2 pounds, 



Tallow ... . . . . 2 pounds. 



Let the corrosive sublimate be put into a vessel with 

 a pound of the tallow, and when warm, let them be 

 well stirred together, and then the resin added, which, 

 when melted, will keep the corrosive sublimate sus- 

 pended. When these are well incorporated by means 

 of stirring, the remainder of the tallow should be 

 added ; and when thoroughly mixed, put in the whole 

 of the oil, and after being well mixed let the salve be 

 poured into a flat vessel to cool ; or it may be allowed 

 to remain in the vessel in which it was melted : in 

 either case keep stirring the mixture until cold.
