Air-leakage-loss by
Although the
valve in the cover
should not be airtight,
the power
lost will only be
in proportion to so
much air as can
rush in in the chamber
before the water
has risen its
utmost.
Besides the force
of gained by the
fall of water
something might
be done by means
of the blast of Air.
See Lewis's Concise
Philos.
The moment
the pressure
within ceases to
be greater than the
pressure without,
that is, the moment
that air ceases to
be driven out the
weight of valve
will make it full
it shut it. That
same moment
the force of the
air in the pond
will force up the
water, & raise the
valve.
Compare the fires
thus gained with
the force that employ'd
in the Chelsea
Water-works.

Philosophy

lowest point to
which the water
is sure to rise.
It will find a
lateral reservoir of any

the water in the
reservoir as high
as the water in

To make a

there should be
cylinders, that while
one is if filling the
other may be emptying.
But Quere, how
will the under valve continue
open when
pressed by a great
column of water
that has already
entered?
To obviate this,
make it tip over
or catch so as
to be prevented from
falling down, untill
disengaged

stationed at the Cover.

Refrigeration
Contrivance for
moistening, for the
sake of cooling, the
part above where the
water rises: otherwise
by being last it will
hold the less air, &
therefore the less air can
be driven out by the ???sh.
