there were no Arguments wanting to prove, that Antimony or the 
Vinum B meticum was poyfon • the ufe of it being then forbidden 
by a Decree of the Faculty of Phyfitians *, and that at this day there 
are no arguments wanting, to prove the contrary, and to afiert , 
That it is a Purgative great importance, follow'd with won- 
derfull effe&s •, the fame Faculty having Publifht a Decree the laffc 
year, by which it permits , and even ordains the ufe thereof. So 
that it ought to befaid, that Sole Experience hath determin’d this 
matter, and that the Recovery of many perfons, and amongft
