 in doses of from twenty grains to two drams. It is often used 

 as a preventive, to prevent horses from taking disease, and 

 particularly those of a contagious nature. For this purpose 

 a portion is tied up in a rag and nailed in the water-bucket, 

 trouo-h, or fastened to the bridle-bit. If immemorial custom 

 is evidence of truth, it must be effective for this purpose. 



Arnica is used in the form of tincture. It exerts great con-

 external bruises and wounds where the skin is not much broken. 

 An ounce of the tincture to one or two pints of water forms a 

 wash of sufftcient strength. It should be applied to the bruised 

 part so as to keep it constantly wet. A cloth w^et in the solu-

 for bruises, sprains, or any local inflammation.

 be used in proportion of one ounce to a pint of water.

 a powerful poison, chiefly affecting the stomach. It has been 

 used as a tonic in from ten to twenty grains daily. It is the 

 principal article used by jockeys as a diqie, given in about five- 

 grain doses, twice a dav, in the feed. It soon undermines and 

 destroys the constitution. I condemn, as not only useless but 

 dangerous, the internal use of this agent. It is used to core 

 out old ulcers. (For the best preparation for this purpose, con
