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 whilst the matter> was yet in
solutis principiis or at least soft, and afterwards
coagulated with the Lapidiscent [p{superscript t}] of the
stone. In confirmation of this conjecture we shall now
observe, that having upon some grounds not necessary to be here mention'd,
suspected that
Granates contain som of them besides som
other metalline substances, divers corpuscles of a
martial nature, I
made choice of some small ones, which by their deep
& almost dark colour, (to name
no other signs) I guess'd to contain somwhat of
<Iron or> Steel
and applyd to them a pretty vigorous Loadstone,
which as I
expected, readily took them
up, & to which they constantly stuck afterwards til I forcibly separated
them from it.
But thô I
try'd this upon more parcels of Garnets than one or two, yet I found that there
was not many
in one heap
that would easily adhere to the Magnet.

Another Instance of the Unlikely uses
to which
an Experiment or practice may be apply'd may be
found in that which follows. One would not
easily
suspect that a ballance should be aplycable to the
resolveing of some Querys in Geography, that
the
Professors of that Science have not
<that I know of> attempted to answer, & seem not
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> there hath been
<as it not rarely happens> questions mov'd which of two or
three
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 afford at
least a Tollerable resolution of the Question. [BP 26, fol. 3v]
<the> Countryes propos'd
<being for Instance> England & Ireland If
<you>
take a map of a
moderate size, containeing as many do the
Geographicall Deliniations of both these Countrys,
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 bounding lines, & if when this
<is> done you lay each of
these thus prepar'd
Maps in a good
Ballance one after another, you will
not only quickly
perceive
<by the preponderancy> which
<of the two Countrys> is of greater extent, but by compareing
their respective weights
you may make at least
a Tollerable Estimate
<of the proportion>
wherein one exceeds
the other in
extent. And tho I readily acknowledge that this way of measureing Countries is
not accurate yet since
if it come but pretty near the Truth, it
may not be useless on an occation, on
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
[Sp{superscript t}] 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.

An ounce of the volatile Salt of Sal armoniac did take of the Spirit
