enlargement has been broken or has disappeared. If not, 

 apply in from five to six days again, scarcely rubbing so 

 hard as at the first application, as the skin is more easily 

 acted upon at this time. But whether one, two, or half a

 the part when dry. The horse's head should be tied up, 

 so that he cannot get at the parts with his mouth. A few 

 hours will be long enough. Place plenty of soft bedding 

 under the feet, so that, by stamping, the horse will not 

 break or hurt his feet.

 dispensed with. Iodide of mercury, occupies, in my estima- 

 tion, in external diseases, as prominent a position as the 

 preparations of aconite do in internal affections, whether in 

 horses or cattle.

 manufacturing chemists ; such as the iodide of gold, and 

 silver — which are of no use in horse and cattle diseases.
