wood since it appeard not possible that in trees of 2 or 300 foot high as there are such between the tropicks
the sap should ascend soe high by filtration which Carryes liquor noe higher than 36 or 40 foot. there
were proposd seuerall querys about the texture of trees in order to consider of their solutions by Expts. as
whether the sap of trees Runs out when ascending or descending or at both times. whether any euer descends
whether there be any trees which being bared of all (euen the innermost) bark will grow. it was Desired tht
more querys might be made & therevpon. the Pret. mr Boyle Sr. R Moray Sr G Ent, Mr Henshaw & mr Hooke

it was made twice wth. the same sucesse vizt. a finch being put into a glasse of the capacity of about a pint
at 5h. 20'. and the air condensd to 1/8 part which appeard by a gage the bird was killd in 24. another was closed
vp in a glasse 4 1/2 as large as the former & left in the common vncompressed air. it appeard very sick at

to try whether he could obserue to a second minute the passing of a fixt starr ouer the zenith and
thence find a parallax of the earths ebb in order to determine the earths motion. after this it
being proposd by the Curator that the Expts. of motion might be prosecuted therby to state it Last
the nature & laws of motion. the Pt. desired that it might be considerd whether it were soe proper
& necessary to try these sorts of expts. since mor Hugens & Dr. Chr. wren had already taken great paines
about that subiect & were thought to haue found a theory to explicate the phenomena of motion by
(Oldenburg. to write to both.).
Oct. 29. 1668. The curator produced an Instrument for measuring a second of time by the or for
making the motion of the Sun to be perceiud euery second. It not being perfect the contriuer was
desired to make it soe against next Day. The same acquaintd the company that all the obseruations
he could make of the Late eclipse of the sun which happend the 25th. instant was only to see the beginning
was. 11h. 5'. matute + some seconds. whereas wing in his almanack has calculated the beginning.
11h. 17'. 09". There was tryd an Expt. of falling bodys in a glasse cane about 4 foot Long Exhausted of
air in which a fether Lett fall. came Down to the bottom in 4". but when the air was readmitted in "6.
the glasse not being well exhausted & too short. a longer glasse to be gott, & be better exhausted -
The Curator mentiond an Expt. made by mr Boyle of including bellows in a glasse exhausted of air to
see what effect the bellows working would haue on the subtile matter remaining in the vessele & whether
it would cause any agitation therein, It was suggested by the Pt. whether a magnet would operate at
a further distance in a thinner then a grosser air, or whether a very thick air would lessen its operation
The curator moued that Expts. might be made to see whether all hard bodys that Rebound doe not
/Wallis psented this as his own. 1672/
soe vpon the account of hauing springy particles in them and that it might be inquired into -
whether there be any body springy vpon other score then that it has air in it. The same concerning
that if there were to be had a body absolutly hard and destitute of all springyness it would not Re
bound at all, and it being said that such a body would not easily be found for making Expt. he an
swerd that it might be tryed comparatiuely. the same tooke notice that glasse was capable of
condensation & Relaxation by pressure & taking off that pressure, and that the parts of glasse may
be putt into a closer posture because they conteine air in them. (2 Expt. of Dr Thruston of transfusion
in a dog. also of cutting a kidney in a liue dog.)
Nouemb: 5. 1668. Dr. Wrens letter about motion) expt. of macassar poyson tryd on a dog.) the curator made
an expt. of
etting a feather fall in a glasse cane about 7 foot long with a head on it which being well
exhausted the feather fell from top to bottom in about 3" of time. but filled againe wth. air the same
fell down in 7 1/2". both were seuerall times repeated. the same proposd the trying Expts. to determine the
businesse of the comunicatio Of motion for which purpose some tryalls had been made formerly wth
3 or more aequall wooded balls of which of the Lateralls had been Let fall against the middle most &
impelled the other Laterall one to the like height from whence the first was fallen soe as the middle stirred very little
vid. Oct. 17 & 24. 1666 he promisd to promised these expt. the next day.
