Ma^r.nm ; of the Plailler of 
Cinnabar, and of the Com- 
pound Diachylon; of the 
Piaifterof Mucileges,of the 
Divine Plaiftcr, and fome 
others. The way to puri- 
fic it is, to aiffolve it in 
Vinegar; then palling it 
through a doth, all the 
Moifture is to be avapora- 
ted away over the Fire. 
By this means it is cleans’d, 
indeed, from Straws, and 
fome other Impurities that 
are contain’d in it : But 
then, part of its Volatile 
Spirits is avaporated at the 
fame time, and in them 
confifts its greateft Virtue ; 
while fome others are fix’d 
by the Acid, which always 
hinders the Motion of Vo- 
latiles. Wherefore I would 
never advife this Purifica- 
tion : I had rather, after 
chuling it as clean as may 
be, only powder it in a 
Mortar, to mix it with 
what may be thought fit ; 
for tho’ there (hould be 
fome little Straws in it,, 
they would never be able 
to alter the nature of the 
Remedy, or diminilh its 
Virtue fo much, as does 
ihe Deftru&ion of its Vo- 
latile Salts by the Vinegar. 
But becaufe it is too moift 
to be powder’d, you muft 
firft cut it into little Slices, ] 
and dry it in the Sun. ’Tis
