r. Hooke shewd an experiment in mechanicks. which was a way
how to take notice of All the Raine that fell; and was designd
as a part of the weather Clock. The
designe. contriuance of this
Inuention was the suspending the Bucket that was to Receiu[e]
the quantity of Raine that fell at any time (whether mor[e]
or Le
sse) soe that according to the quantity therein conteind
the place thereof should either be higher or Lower but cer=
tainly Determined, this was performed by a counterpoy
se
to the said Bucket. The counterpoyse was contriud two way
either by a string of
Bulle Leaden bullets soe orderd tha[t]
when the bucket was quite empty all the bullets re
sted
vpon a table, but when there fell as much water into the
bucket as equalled
the weight of one of the Leaden Beads, the[n]
the Bucket Di
scended one space & one Bullet was Lifted vp
/&/
but when twice as much; two bullets, & when three times as much
3 bullets were lifted and soe forward, till all the bullets were
Lifted vp, and the Bucket had De
scended to its
spa place of Emp
tying, wherevpon the chaine of Bullets presently De
scended &
Lifted vp
the Bucket into its empty place. But becau
se this
motion proceeded w
th. jumps and was not continually equall
Therefore A 2
d. contriuance was al
so shewn which was.
This. The counterpoi
se to the Bucket when Empty was a Cy=
linder
which was immersd into water,
, or any othe[r]
fluid. which

as the Bucket receiued more & more water was continually
