I have elsewhere endeavor'd to show, that
divers if not most are the real vertues of some gems, for there are too many
fabulous ones ascrib'd to them, proceed from the particles of mineral juices
<that were admitted
[ 'into as' deleted] whilst the matter> was yet in
[ 'ei' deleted] solutis principiis or at least soft, and afterwards
coagulated with the Lapidiscent part of the
[ 'Sin' deleted] stone. In confirmation of this conjecture we shall now
observe, that having upon some grounds not necessary to be here mention'd,
suspected that
[ 'in' deleted] Granates contain som of them besides som
[ 'of' deleted] other metalline substances, divers corpuscles of a
martial nature, I
[ 'chose' deleted] made choice of some small ones, which by their deep
& almost dark colour, (to name
[ '[approximately 1 character illegible]' deleted]
no other signs) I guess'd to contain somwhat of
<Iron or>[replacing 'If'] Steel
[ 'or Iron' deleted] and applyd to them a pretty vigorous Loadstone,
which as I
expected['ex' inserted, replacing 're' deleted], readily took them
up, & to which they constantly stuck afterwards til I forcibly separated
them from it.
But['B' altered from 'T'] thô I
try'd this upon more parcels of Garnets than one or two, yet I found that there
was not many
in['i' altered from 'o'] one heap
that would easily adhere to the Magnet.

Another Instance of the Unlikely uses
to which
[ 'a try'd' deleted] an Experiment or practice may be apply'd may be
found in that which follows. One would not
easily['eas' altered from 'read']
suspect that a ballance should be aplycable to the
[ 'Deter &' deleted] resolveing of some Querys in Geography, that
the
[ '[approximately 1 character illegible]' deleted]
Professors of that Science have not
<that I know of> attempted to answer, & seem not
[ 'to have t' deleted] so much as to have thought determineable without
much Labour, & good skill in the Geodeticall part of Geometry. And yet I
remember
<as> that when
<
as>[replacing 'in discourse'] there hath been
<as it not rarely happens> questions mov'd which of two or
three
[ 'Countries' deleted] Countrys discoursed of was the biggest, or by
how much one of them exceeded the other, or fell short of it, I bethought
myself of a way, which tho not accurate
May[altered from 'did'] afford at
least a Tollerable resolution of the Question. [BP 26, fol. 3v]
<the>[replacing 'If for Instance the'] Countryes propos'd
<being for Instance>[replacing 'were'] England & Ireland If
[ 'too' deleted]
<you>[replacing 'would take']
take['a' altered from 'oo'] a map of a
moderate size, containeing as many do the
[ 'del' deleted] Geographicall Deliniations of both these Countrys,
[ 'and with' deleted] upon as even & uniforme a Paper as you can make
choice, of & with sharp pair of Sisers follow
<close> the outlines or Boundaries of each of those Countries,
how crooked soever those lines happen to bee, clipping off & laying aside,
whatever parts of the paper are not comprehended within
[ 'those' deleted] those bounding lines, & if when this
<is> done you lay each of
[ '&' deleted] these thus prepar'd
[space of 6-7 characters] Maps in a good
Ballance one after another, you will
not[altered in composition] only quickly
perceive
<by the preponderancy> which
[ 'Country' deleted]
<of the two Countrys> is of greater extent, but by compareing
their respective weights
you[altered from 'one'] may make at least
a Tollerable Estimate
<of the proportion>
wherein['w' altered from 's'] one exceeds
the other[altered from 'another'] in
extent. And tho I readily acknowledge that this way of measureing Countries is
not accurate yet since
[ 'tis difficult to find one find & practice one that is so' deleted]
if it come but pretty near the Truth, it
[ 'need' deleted] may not be useless on an occation, on
[ 'Geographers have not that I know of taught us' deleted] which tis
difficult to find and practice a method that is exact.

In the Adiaphorous mixture to a Couple of Ounces of Salt of Tartar
and as much volatile Salt mingled together we imployd about seven ounces and
about an halfe to satiate them seemingly in the Cold. But upon the Destillation
of this mixture the ascention of some volatile salt and the urinous tast of the
first spoonfuls of Liquor that came over, argued that there had not been
Spirit enough put to the salt.

Upon an Ounce of Salt of Tartar we put by degrees spirit of Venus
till the Salt was dissolv'd & there was no more conflict between them &
found that {ounce} iii of the spirit -- {drachm}
i{half} -- 12 gr did dissolve & satiate the ounce of
the Salt.
