 cefs we have the entire Complexion of a Vegetable 

 under the Form of a Sapo, or Balfam, (efpecially if 

 inftead of common Water for the Lixivium we make 

 ufe of the diftill'd Water of the Plant) a Compofi- 

 tion, peradventure, as beneficial to Mankind as any 

 other whatioever. The little Experience that I have 

 had in the World hath fufficiently convinced me (tho* 

 I am unhappily a little inclin'd to Scepticifm and In-

 in mapy Cafes, internally given in proper Vehicles,

 jefuits-Bark, I believe it may be one of the beft al- 

 terative Medicines yet commonly known. I beg, 

 .Sir, a few of your Thoughts concerning the £hiin? 

 quina, as to the Place of its Growth, and its Hiftory. 

 Peradventure it may be an Eaft-Indian Drug, and 

 brought from the Moluccoes to Peru. I am much in 

 the dark, and want fome of your learned Communi- 

 cations about it. What Bartbolinemd Signior Badi
