r: Charras being Present before the sitting of
the Society at their
Experiment presented
the his booke Entitled Pharmacopea Royalle
It was Deliuerd to m
r Hunt for
the Library.
RH produced an Experiment of weighing
and solid bodys by the help of a
paisebuoy /in/
of water
the affecte of wch was to the exactne
sse of a
millionth of/.. . ./ millionth ^/part/ of
times its weight. Soe that hereby any body /euen to the weight of a tunn/ might be examined as to
its its vari
ation of weight euen to the weight of a /few/ graines by means of which Infinite
of Di
scouerys might be made of the various alterations and changes that happen
in bodys w
ch. are not po
ssible to be Di
scouerd by any other way whatsoeuer
Especially as to the curious and otherways in
sen
sible alterations that
happen in the body of man.
The contriuance
in short was this a cylindricall ve
ssell ^/of tin. though gla
sse is much more preferrable/ of a bulk large enough
to counterbuoy the weight of
the body de
signd to be examind
was putt was
by perfect
ly soderd vp soe as neither to be peruious to air or water. to the vpper part of this was
sodered fowr small wires
about reaching about 2 inches aboue the top of the cylinder
vpon the ends of the
se wires re
sted a cro
sse:
of breadth enough the ends of w
ch. were
long enough beyond the Receptacle ve
ssell to Receiue 4 lines to w
ch. a seale
was fa
stned vnder
which was neath the Receptacle ve
ssell into w
ch. seale the weight
to be examined is putt. the manner of w
ch. will be better vnder
stood by the annexed scheme
Leaue half a side
D
r croon alledged that this was nothing Differing from the floating of a
great ship and that the same thing might be done w
th the weighing of a
ship w
th. scales. But it was shewd that the nicety of this Experiment -
Depended vpon fundamentally totally Differing, And though twas impo
ssi
ble to find the Differing alteration of weight in a ship by the way
of a ballance or by its sinking to the thou
sandth part of its bulk
by this means the Differing alterations
not only of^/
a body as big as/
a ship butof any
other greater of Le
sser body whatsoeuer might be found to the 1000000
thpart - The
.. . . ship vpon euery inch of sinking varying many tunns -
weight. But a Body as bigg as a ship this way orderd not varying an ounce
weight vpon the sinking seuerall feet. this was Demon
strated from the
variation of the Location of the ponderating body by mediums of exceeding
great Diuersity in their specifick grauitys. the specifick Grauity of the
vper to the specifick grauity of the vndermo
st being aboue a thou
sand to one
as is manife
st by other experiments which haue been formerly Exhibited in this Society
After the minutes of the La
st Day were read. and during
the Reading the
President came -

the Doing of w
