vniuersall Dissoluent of all sulphureous bodys and that this Dissolution is fire
adding that this was done by a nitrous substance inherent in & mixed wth the air
the Expt. was that he tooke some liue Coles & putt them vnder a glasse vessell where
vpon the sd cole after a very little time went out, but then being taken out &
exposed to the free air Recouered its Burning, it being objected that it was the agita
tion of the air driuing the Igneous particles into the combustible body which made it
burn & consume. mr. Hook answerd that Expt. would shew that a burning body tho
agitated would be extinguished if it had not a free accesse of fresh air. he added
that a combustible substance kept Red hott yea in a fire as hott as to melt coper
would not wast it, but as soon as fresh air was admitted did Burne away and
consume. An Expt. was mentiond to shew that a burning cole wanting fresh air
would keep intire but brought into new air would fall in peices. mr. Boyle sug=
gested that a pair of strong bellows being taken & the clack stopt & the nose mad fast
wth Cement to a Receiuer into wch a burning Cole is conueyed a wind should be made
by forcing the bellows to & from, to see whether it will make the cole burne
It was ord: that these expts. should be made ready for next Day (Dr. godderd sugested
the Lord Bacons Expt. of putting a wood cole into a close iron box and keeping it in
a good fire to see the euent) (mr. Willouby Returnd from trauells, he presented a Cutt

2 blacker spott mouing therein which Sigr Cassini had first giuen him notice of
conceiuing them to be the shadows of the satellits which he had seen come out of the occi
dentall Disk of the planet). mr. Hooke mentiond that he had seen may the19th
1664. about 9 at night a small spott in the biggest of the 3 black belts of and
that obseruing it from time to time, he found that with two howres after the said
spott had moued from east to west about half the Length of the Diameter of
Orderd that the Society be summoned the next wensday for the Election of mr
Hooke as Curator by office to the Society who was by the President Recom
mended from the Councell to the Society -
Ian: 11. 1664/5 His majty. on Ian. 9. writ himself Charles R Founder. and his Highnesse the Duke of York
Iames Fellow ? (copper stones.) Mr. Hooke made 3 expts. Conceiued by him to confirm his formerly
proposed hypothesis about fire. the one was wth a pipe hauing sulphur in it sealed vp herme
tically, which though made Red hot yet burned not, but as soon as the air was admitted
Burned away. the other was that charcole put into a pipe and heated Red hot did
not at all consume or burn. The 3 a charcole put into a chrusible wth sand was kept
in a very great heat for about 2 howres. and taken out after it had been suffered to stand
to cool, was found Scarce sensibly Diminished. It being objected that the air in the
vessells being superonerated wth the steames of the wood, was the cause of the not Burning
It was Replyed by mr. Hooke, that an expt. should be made to shew, that though the aire
were not thus superonerated yet the burning substance should goe out, vpon the accout
of wanting fresh air, and that this should be done by drawing the air out of the
vessell and making thereby the smoke fall downe. The same proposed an Expt to
be made next day, by blowing forcibly, wth. a certaine contriuance, the air included in
the box vpon the coles without making the coles Burne.
mr. Hooke was Elected (Curator by office to the Society, and that for perpetuity wth a salary
of 30ll. p' annum pro tempore (majr. Holmes his account of 2 pendul watches carryed wth him
to Guinny.) mr. Boyle Exp: Hist. of Cold) cold /there/ so great as to freez white wine Renish Claret
and Euen Sack.) more about cold. from mr Boyle) his maj. expt. about frost.)
mr. Hook produced his Thermometricall standerd for heat & cold, and gaue an account how it
had been made. vizt after the manner Described in his micrographia. this was Looked vpon though
not exact yet better then the other ways hitherto vsed (The first Iournall de Scauans. also Iohn Dan

Hook should consider of the engine mentiond to produce air by the fall of water
