nent to annex to the other Circumstances
that have been already see down concern
ing this Experiment, That it was made in
Winter, in Weather neither Frosty nor
Rainy, about the change of the Moon,
and at a place whose latitude is near about
51d and a half: For perhaps the force or
pressure of the Air may vary, according
to the Seasons of the Year, the tempera
ture of the Weather, the elevation of the
Pole, or the phases of the Moon; all, or
even any of them seeming capable to al
ter either the heighth or consistence of the
incumbent Atmosphere: And therefore
it would not be amiss if this Experiment
were carefully tryd at several times and
places, with variety of Circumstances.
It
might also be try'd with Cylinders of se
veral Diameters, exquisitely fitted with
Suckers, that we might know what pro
portion several Pillars of the Atmosphere
bear, to the Weights they are able to su
stain or lift up; and consequently, whe
ther the increase or decrement of the re
sistance of the ambient Air, can be re
duc'd to any regular proportion to the
Diameters of the Suckers: These, and
divers other such things which may be
try'd with this Cylinder, might most of
