Analysis of nitre (margin, on p. 191)
2
Tbd
D
To render the more probable some Chymical Opinions of mine, I
caus'd to be taken {pound} i of purify'd Salt peter, &
three pound of good White Clay, which being powder'd & diligently
incorporated with the Salt, the Mixture was put into a strong Hassian Retort,
& distill'd with a naked fire, gradually increas'd till at length it came
to be very strong. By this means we obtain'd about nine Ounces & a half of
very strong Spirit of Nitre, that emitted red Fumes into the upper part of the
Glass, thô it were closed with a Glass Stopple ground to it. The Caput
mortuum weighed {pound} iii & four ounces. So that in
Spite of all the Laborants Care, who endeavour'd to make the Experiment exact,
as He was told I intended it showed be, there wanted about ii {half} {ounce} of the four pound committed to Distillation.
And yet we obtain'd much more than is usually afforded, when the Distillation
is made with Earthen Long-Necks. For when the Laborant made the Spirit to sell
for His own benefit, He usually obtain'd but somewhat more than five ounces,
& seldom so much as six, out of a pound of Nitre. But the Phænomenon
I mainly intended in this Operation was such as I look'd for. Since thô
the Clay appeard [BP 21, p. 192] by its weight to have retain'd
four ounces of the Nitre, yet when it was carefully Lixiviated, even with
scalding Water, the Laborant could get out but about 5 grains of Salt, that
would pass through the Filtre: & that it self I judg'd by the Tast to be
rather of a Nitrous Quality than of a Lixivial. With which it agrees well, that
we[altered from 'it'] did not find
this Salt to produce a yellow Precipitate with the Solution of Sublimate, as
Fixt Alcalies are wont to do.

An uncommon Experiment
about Respiration
Tbd
We put a Mouse into a Glass, of which He fill'd, according to our
Estimate, about a 5th part. To this we fasten'd very close, but not without
difficulty, a Lambs Bladder, whose Capacity seem'd not to differ much from that
of the Glass,
<I mean, when> when it was full blown: for when we tyd it
upon the vessel, we had
[ 'caref' deleted] by wreathing it & otherwise, carefully squeez'd out
[ 'almost' deleted] the greatest part by far, of the Air. This dilatable
Receiver, (as for distinctions sake I use to call such a vessel) was put into
another Receiver, so contriv'd that part of the Air might be suckt out, without
a Pump. But the Exsuction was not
<then> made so great, as to
[ 'fill' deleted] distend the Bladder near so much, as it was capable of
being. And, thô this Expansion of the Air in the dilatable Receiver, did
so far rarefye it, that it appear'd to molest the included Animal, & made
him often shift places
<and postures>; yet it did not appear to make him very sick, or
cast him into convulsive motions. Wherefore to compleat the Experiment,
<& show, that
thô a moderate Rarefaction of the Air (as if it be
expanded about a
5th or 4th part)
makes it not altogether unfit for respiration, yet an
expansion to double the Room or a little more, may make it so;>[insertion in margin ] we did, by
the help of an exhausting Glass, so rarefye the Air in the outward Receiver,
that the Air shut up in the Dilatable Receiver, passd so plentifully out of the
Glass into the Bladder, as to display the Folds & Wrinkles, &
fill['f' altered from 'j'] it as if it
had been blown
<up>[replacing 'full'] with a pair of Bellows. And by this means the expanded Air in the
whole Receiver, being brought, by our Estimate to take up twice as much room as
it did before, this expanded Air became too rarefy'd, to be fit for Respiration,
& the Mouse, after several
<vain> attempts to get out, grew presently very sick, & fell
into strong
<& differing> Convulsive Motions, by which He was quickly
laid upon his back, with his trembling Feet upwards, & appear'd
<to be> upon the very point of death. Wherefore making hast to
let the
<Ambient Air into the> outward Receiver, the Bladder was thereby
made to shrink again, & the dilated Air it contain'd was repell'd into the
Glassy part of the Vessel, & so acquir'd its former density, & becoming
fit for Respiration, quickly recover'd, thô not all at once, the fainting
Mouse, which within a very few Minutes was in a condition to make use of the
liberty I gave it, to make its Escape.

some little noise that was produc'd distinct from that of the cracking of the

a furnace for

Being minded to repeat an Experiment I had many years ago made,
when I chanc'd to be in the Country in a place where I could procure no
furnace; I caus'd to be taken half a bushel of Wheat-bran, & five pints of
common Water. These were mix'd together in a Wooden Pale that was very tight
upon Friday the 5th of August; but having been press'd too close together,
there['re' altered from 'y'] was
produc'd but little Heat for above two Dayes: & then the Matter being
stirr'd, that it might be more loose &
[ 'open &' deleted] accessible to the Air, the
<Heat> quickly
[ 'q' deleted] increased, & invited us to place in the midst of the
Pale, a pretty large Body & Head of Glass, with a fit quantity of common
Brandy in it, by which means in about 3 dayes We had in the Receiver about half
a Pint of Spirit very diaphanous, & more pleasant than the Liquor that
afforded it. After this, the Heat being decay'd, but not
[ 'quite' deleted] lost (for it was still greater than to be measur'd by a

but without the Addition of Water it quickly grew so hot that we were invited
to put some crude Urine, which had been kept above 6 weeks in Putrefaction,
into the same Body, after we had pour'd the Spirit of Urine out of it. And this
crude Urine did, as we expected, afford us as great a proportion of good Spirit
of Urine as we thought it worth while to draw. And now upon the 17th of August
the Matter (which begins to smell strongly, & abounds in Maggots) seems to
be as warm as ever. So that when
