Accounts of thefe Stones, it feems tome fo be this, that 
they are ali but different forts of the Pyrites : But if I 
be miftaken in this Matter, I defire that you would fet 
me right, nnd inform me better. But howev^er this may 
be, though thefe things had their weight vvith me, yet 
another thing feemed itili to increafe my Sufpicions ; I 
I could fcarce bringmy filf to believe that a thing of this
