Wherefore I bethought my ſelf of an
other way to ſatisfie in ſome meaſure my
curioſity, to wit, by means of a certain
Liquor, which I call'd to minde that ſome
years ago I had (for a deſign that belongs
not to our preſent purpoſe) prepar'd;
which, I ſuppoſe, I ſhew'd Your Lord
ſhip, and which had the luck to be ta
ken notice of by divers very Ingenious
and Famous Men. For this Liquor,
though moſt of its Ingredients be Metals,
and all of them ponderous enough, is yet
of that nature, that whilſt the Viol where
in it is kept is ſtopt (how ſlight a Cover
ſoever) both the Liquor and the Glaſs
are tranſparent; and ſo is that upper half
of the Glaſs to which the Liquor reaches
not. But aſſoon as ever the ſtopple is ta
