 water ; the balsam to be well shaken together previous 

 to using it. The blister is to be well rubbed on the 

 joint, till a plentiful discharge takes place from the 

 surface, when it becomes no longer requisite. By this 

 treatment a cure is generally effected, unless when the 

 bones are materially injured along with the soil parts, 

 and then any plan of cure will prove ineffectual.

 ning of the joint-oil is stopped, which is generally the 

 case, a plaster of pitch, &c., as recommended above, 

 should be applied." — SkelleCs Treatise,

 that the medicine may have the better effect. Afler

 parts affected, which may be repeated every three or 

 four days till a cure is effected ; and it seldom requires 

 more than two or three applications :
