I remember I have, in a Diſcourſe con
cerning Fluidity and Firmneſs, made
mention of my having, by the exſuction
of the Air out of a Glaſs Veſſel, made
that Veſſel take up, or ſuck up (to ſpeak in
the common Language) a Body weighing
divers Ounces; but our Engine affording
us the opportunity of making conſider
abler Experiments of that kinde, We
thought fit to make a further tryal of the
force of the Atmoſphere's preſſure up
wards, after the following manner.

The Receiver having been exquiſitely
cloſ'd, as we have often taught already,
and the Air being in a good meaſure drawn
out of it, it was remov'd from off the
Pump: and to the lower Branch of the
