 by the name of Thoro'igh-wort or Bone-set. I have 

 stated a case of its efficacy in those diseases in a letter 

 to William Royston, Esq who inserted it in the Me- 

 dical and Physical Journal. In which I stated the 

 benefits derived from this plant, by myself and others 

 during my stay in the neighbourhood of lake Ontario,

 yellow fever) were raging among the inhabitants. It 

 ' is generally used as a decoction, or, which I consider 



the more effpctual way, as an infusion in gin or rum.
