Lately made about Iupiter. vizt Iune 26 wth. a 60 foot glasse. It was ordered to be Registred.
There was also presented to the Company the obseruations of the Late Solar Eclipse made by mr. Willoughby by Dr Pope
mr. Hooke and mr Philips which was likewise orderd to be registred. (Dr. Pope brough in the Dimensions of an oxe of

Iuly. 18. 1666. (Sr. R Moray pes: Ores, figurd stones, also 96 Roman Brasse medalls) these were deliuerd to the Keeper
of the Repository mr Hooke (also a wasp nest) Ld Sanwiches Letter. Orderd ____ & that Dr. Pope & mr Hooke
should ioyne in making obseruations answerable to those intended to be made in Spain (antelope skin) corroded
glasse) oat ale. vitriolate spring strongest in September) There was tryed an expt. wth. Sal Armon: & salt peter
to see which of the two had the greatest force to cool. the expt. not being orderd as it should be. The Curator
was charged to Lett it be made at the next meeting wth. both the salts putt into an aequall quantity of water, in the
same vessell obseruing the same time with both. The circular pendulum applyed to a clock being inquired after
the pt. affirmed that he had made tryall of one. and obserued the motion of it for 4 dayes. in which time it had gone
soe aequally wth. his pendulum Clock that after those 4 dayes were elapsed he found it only to haue gone one minute
too fast.      The Expt. wth. the pendulum and two balls, not yet succeeding it was Referred till next day
when also the expt. shewing that a circular pendulum is the same wth. two pendulum crossing one another
was orderd to be made.
Iuly 25. The Expt. of Cooling water wth Sal armoniac & salt petre was tryd separately, the spt. of the sealed
Thermometer standing at 12 1/2 degrees, and hauing first subided in the cold water as farr as it could vizt to
8 1/2 degrees a quarter of a pound of sal arm: was putt into it at 4h. 56' wherevpon the spt. descend to 4 1/2. degrees
[In margin]14.   in 8 minutes. and after that time was found to Descend noe lower. Then into the like quantities of water
in a like glasse vessell was put the same sealed Thermometer after it had Recouered the height of 8 1/2 degr
and then a quarter of a pound of salt peter being put in at 5h. 13. the spirit descended a Little below
4 degrees in the space of 7 1/2 minutes. some of the company expecting that the salarmoniac should coole
more potently then the niter scrupled the goodnesse of the sal armoniac, but mr. Hooke affirmed that it was
very good. It was tryed with bay salt but that made the spirit descend from 8 1/2 degrees to 7 1/2 in 5
minutes. It was orderd that mr. Hooke should priuately try the same Expt. againe and adde
some others of the same Kind and giue an account of it to the company at their next meeting
There was also tryed the Expt. to shew that the circular pendulum is the same wth. two pendulums
crossing one another. But it was orderd that the next Day the same should be repeated
with making the Contriuance soe as that the centers might be in the same plaine, and
at a greater Distance: The expt. frequently made to Represent the Earth & moons com-
pounded motion by two balls suspended on a line being found not to answer expectation
(which was to see whether the center of grauity be in the middle of the ellipsis) was Layd aside
