dose of niter is from two to four drams dissolved in water. It 

 is often given in combination with digitalis, sulphur, etc. 



Po])lar harJc is alterative, changhig dull action of parts, and 

 tonic. There are few articles more deservedly popular in the 

 treatment of the horse than this. It may with advantage 

 enter into nearly every prescription given the horse to im- 

 prove the condition of his system. It has a very happy effect 

 on the stomach and bowels, and also on the kidneys. The old 

 fashion of putting a poplar pole in the stall for the horse to 

 gnaw at is a good practice, and especially if the animal is not 

 in good condition. Powdered poplar bark may be given in

 It is very useful in farcy, strangles, malignant scarlet-fever, 

 grease, lice, mange, fistula, and poll-evil. The dose is from 

 half an ounce to an ounce, twice a day. In some of the
