may be made to cohere very ſtrongly,

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.
