I hope I ſhall not need to reminde Your
Lordſhip, that I have all this while been
ſpeaking of a Vacuum, not in the ſtrict

And therefore I ſhall now proceed to
obſerve in the laſt place, that our 33d Ex
periment affords us a notable proof of the
unheeded ſtrength of that preſſure which
is ſuſtain'd by the Corpuſcles of what we
call the free Air, and preſume to be un
compreſſ'd. For, as fluid and yielding a
Body as it is, our Experiment teaches us,
That ev'n in our Climate, and without
any other compreſſion then what is (at
leaſt here below) Natural, or (to ſpeak
more properly) ordinary to it, it bears ſo
ſtrongly upon the Bodies whereunto it is
contiguous, that a Cylinder of this free
Air, not exceeding three Inches in Dia
meter is able to raiſe and carry up a
weight, amounting to between ſixteen
and ſeventeen hundred Ounces. I ſaid,
