1ous a Pipe of Lead, as that deſcrib'd by
our Author, ſince we ſee in the Heads of
Stills, and the Necks of Æolipiles, how
quickly ſuch vapors are even by a very lit
tle cold recondenſed into Water. But
to this alſo ſomething may be ſpeciouſly
reply'd; wherefore contenting my ſelf to
have mention'd our Authors Experiment
as a plauſible, though not demonſtrative
proof, that Water may be tranſmuted in
to Air. We will paſs on to mention in
the third place another Experiment, which
we try'd in order to the ſame enquiry.

We took a clear Glaſs bubble (capable
of containing by gheſs about three Oun
ces of Water) with a Neck ſomewhat
long and wide, of a Cylindrical form;
this we fill'd with Oyl of Vitriol and fair
water, of each almoſt a like quantity, and
caſting in half a dozen ſmall Iron Nails,
we ſtopt the mouth of the Glaſs (which
was top-full of Liquor) with a flat piece
of Diapalma provided for the purpoſe,
that accommodating it ſelf to the ſurface
of the water, the Air might be exqui
ſitely excluded: and ſpeedily inverting
the Viol, we put the Neck of it into a
