1Phænomenon to what I have ſeen happen
in the diſſolution of Seed-Pearl in ſome
acid Menſtruum, in which, if a good quan
tity of the little Pearls be caſt whole, they
will at firſt, if the Menſtruum be ſharp e
nough, be carryed in ſwarms from the
bottom to the top of the Liquor. We
will adde, that without ſealing up the
Glaſs, this Experiment may be try'd in
one of our ſmalleſt Receivers, for there
the exſuction of the ambient Air may be
perform'd ſo nimbly, that immediately
the bubbles lurking in the Water are al
low'd to diſplay themſelves, and aſcend
in throngs; inſomuch, as having in ſuch
a Receiver try'd the Experiment with
Wine (as a more ſpirituous Liquor) in
ſtead of Water, the Red-Wine appear'd
all cover'd, with a copious, but vaniſhing
white Froth, almoſt as if a Veſſel full of
bottl'd drink had been unwarily open'd.
