if you look narrowly, take notice of a
multitude of ſmall bubbles all along the
inſide of the Tube betwixt the Quick
ſilver & the glaſs: (not now to mention the
Particles of Air that lye conceal'd in the
very Body of the Mercury) Many of
which, upon the Quick-ſilvers forſaking
the upper part of the Tube, do break in
to that deſerted ſpace where they finde
little or no reſiſtance to their expanding

Bodies to the emptyed part of the Tube,

of Linnen cloaths dipped in Water, to
the ſame part of the Tube, the Quick
