1imaginable how this Phænomenon could
proceed from any miſtake in trying
the Experiment, yet the ſtrangeneſſe
of it invited me to repeat it with freſh
Spirit of Wine; which, ſwelling in the
Neck as formerly, I left all Night in
the Receiver, allowing free acceſs to the
external Air at the Stop-cock, and the
next day found it ſtill expanded as be
fore, ſave that it ſeem'd a little lower:
which decrement perhaps proceeded from
the avolation of ſome of the fugitive
parts of ſo volatile a Liquor. And for
better ſatisfaction having taken out the
Glaſs, and conſider'd it in the open Air,
and at a Window, I could not finde that
there was any remaining Bubbles that
could occaſion the perſevering and ad
mir'd expanſion.

BEing deſirous to diſcover what diffe
rence there might be as to gravity and
levity, between Air expanded under Wa
ter, and it ſelfe before ſuch expanſion; we
took two very ſmall Viols, ſuch as Chy
mical Eſſences (as they call them) are wont
to be kept in, and of the ſize and ſhape ex
preſſed by the 8th Figure: into one of theſe
