for Grinding and pressing of cyder by the help of cylinders toothing one into an other yet he
appeald to theire Register to proue that he had some years before such patent propounded it to
the Society and that the Society had accordingly orderd mr Shortgraue to make tryall of such
indented cylinders. vpon this much Discouse arose concerning cyder. mr. Packer affirmd that by
grinding and pressing out the juice of the apple at once a Cyder might be made as cleer as rock
water wch. would neither haue any lees or turn brown ^ /& that mr Fettyplace of Battersey had made such juice & kept it cleer 15 dayes/ but if the pulp were sufferd to lye after
it were beat ^ /sometime/ before it be pressed, the Iuice will both turne brown & yield abundance of lees
this was supposd by to come from a kind of putrefaction begun in the fibers of the Apples before it
be pressed, other supposd it a kind of fermentation, and there was much said by RH to shew
that fermentation Differd from Corruption and that they were the working of Differing parts
one upon and another, and those performed Differing ways for twas obserud that the substances
whelst together in the apple would Rott but when separate in the Iuice or Liquor they
would ferment. It was wished that tryall might be made what kind of Spirit would
be producd by Distillation of mellow apples more than of Green ones and fresh gathered
Dr. Grewe affirmed that odoriferous plants would yeald a spirit wthout fermentation, but
It was answerd that though they yealded an odoriferous substance yet that could not pro
perly be calld a spirit at Least it was not of the nature of a spirit made by fermentaco
which was calld a vinous or burning spirit, the other odoriferous substance might
more properly be called the transpiration or sweat of the plant. very analogus to
that of animales by wch. they are distinguished one from the other very plainly by
the smell. About fining of liquors. Sr. I hoskins affirmd that any opaque liquors/thick & muddy Cyder//thick or muddy Cyder/
may be clarifyd by very fine strainers. others affirmd that/fish glew dissoluied/beating some Eggs
wth. some of the liquor & then mingled ing them & putting together wth it would doe the
same things. as also eggs beaten & broken wthsome of the Cyder and then mingled wth. the whole
mr. Henshaw deliverd to mr Hook. ^/read/ a Letter ^/whichwas^/had been/ deliuerd him by mr Henshaw to whom it was/Sent when by th Lord Brounker - the effects
of wch. was that Mr. Lewenhook the writer thereof vnderstanding mr Oldenberg
was dead Desired to know to whom he might address his letters for the
future and therein included Seuerall testimonialls of his former Expts. and
an account both in Dutch & latin of some new obseruations-.
The consideration of wch. was adiourned to the next meeting in the mea[n]
time R H ^/mr Hooke/ was desired to make a microscope after a way wch. he proposed
as very likely to doe as much if not in the same manner as tht of
Lewenhook -
R H. produced an Ephemerides of 12 eclipses of Saturne by the moon toge
ther wth. the transitus of through the sun ^/and a calculation of Eclipses for the two succeeding years. one of wch is omitted in Heckler/ which was inclosed in a letter
to him from Gotefried kirch . of Hamborough some Coppys of wch. he
promisd to Deliuer to Some Astronomicall Observers.

RH related that sergeant Piles had affirmed that by rasping his apples wth. a
bread grater he was able to make almost a 3dpart more of Cyder than
by the common way. and the same mentioned are expedient Of rasping those
apples much easier by help of a cylinder couerd wth. tin plates made of the form
of a Grater. the Hap whereof is ^/here/ annexed.
To wch suggestion mr. Packer obiected that though by that meanes a 3d
part more of Liquor ^/was obteined/ yet the quantity of faces after setling would be soe
great that Little more cleer cider could be made that way then by the comon.
