for to oblige me to admic mca- 
lefcent Mercuries, it ought not 
to fuffice, that 'tis pofiibleor

poffeffion of this Mercury , f 
found in fome of their Booksj 
that Chymiits callPhilofophers, 
fonie dark paflages , whence 1 
thengheff'd their knowledge of 
it, or offoine other very like it ; 
and in one of them I found , 
though not all in the very fame 
place, an Allegorical defcripti- 
on of it, the greatefi: part of 
which was not very difRcult for 
me to underftand ; but not find- 
ing there any notice taken of the 
property of this Mercury to 
grow hot with Gold , I was in- 
duced to fufpeft,that either they 
had not the knowledge of it, or 
judgd ,ic unfit to be fpoken of. 
But you will, I fuppofe, expeft
