At length Grill himself
having taken part of Cinereous,
or Ash-like Lead, with the Star
adhering, cupellated in a Test,
and found from one ounce of this
Lead, twelve ounces of Cupellate
Silver, and from these twelve ounces,
he also had two ounces of the
best Gold. And I Helvetius am able
to shew some of this Spongeous
Lead with part of the Star yet adhering,
& besides the pieces of the Star
the Silver and Gold made thereof.
Which when this Subtile (and
Likewise Foolish) Grill understood,
he would not be known to Knottterus,
whether he had used the
Spirit of Salt, or not; but thenceforth
attempted to learn of him
the Art how to make it; yet some
time being Elapsed, the worthy
Knottnerus had for got what Spirit
of salt (for he was expert in
various kinds thereof) he had given
him; not being able to call
the same to mind so suddenly: in
the mean while, he and his Family
were visited with the Pestilence
and dyed: the other falling into
the Water was drowned. After
the death of these two, none
could find out the way of either of
their Operations.
Certainly here is cause of Admiration,
that the Internal Nature
of Lead, by the simple maturation
of Spirit of Salt, should appear
in an external form so noble.
