No 5

Detach a Barrel,
it will float, &
may thus be dropped
on a sloping stage
to the entrance of
the Conservatory.


For The Receivers for
the temperature preserving
Machines
apply to the Glassmen
who make the
Confectioners Glasses,
and the Musical
Glasses, which are
made in sts,
and probably with
great accuracy as to
the forms & sizes.


Per S.B Currants
are kept in Russia
in Water - The
Water serves at any
rate to exclude the
Air, and the temperature,
it must be
supposed, is low enough
to be a bar to
fermentation.

The Water serves
as a bar to great &
sudden changes of temperature.


(No 3 in this Machine
shall be as great as of
No 5 in Machine I

Or rather double the
thickness of the temperture -fence only
the thickness of the
Ice remaining the
same as in Mach II.

The Hot Conservatory
business would
in most instances
be best managed
by a Balneum -
The temperature
might in this way
be more easily re-
exactly and speedily
indicated, and thence
as well as in other
increments more
exactly regulated.

By means of
a common Stock
Reservoir of water
kept constantly boiling,
any number
of vessels might
be kept near one
another in so many different
degrees of temperature.

So likewise the
Cold Conservatory.
The temperature
of water being much
steadier much less
speed liable to sudden
variation than
that of air - See
Kirwan. 30-38.

The water in the
Balneum (Cold) should
be capable of being
agitated, to keep the
temperature steady,
by mixing the parts
changed with the parts
unchanged:

The difference in
gravity between warm
& cold water makes
a gradual mixture,
but a storm expidites
it. Kirw. 35.

Temperature
Tepidarium

For elevation, a
lamp constantly
burning:

For depression, a
body of mercury
in the thermometer
principle, so ordered
as that when the
heat is above the
degree required, the
expansion of the
mercury shall by
its weight open a
door that shall admitt
cold water,
which by the re- contraction
of the mercury,
will bring
shut the door again,

One way of doing
this might be by
a Ball Cock, floating
in Mercury,
or Quere in Water?)

Might it not
bear against a
Spring?

A cork, with a
rod through it {Sketched diagram}
to float in the
mercury: the
mercury rising
pushes open
a valve, of
some weight,
but as little
friction as possible,
and closing
air-tight.

One use of the
Tepidarium, proving
the preservability
of fresh meat &c
proposed.

In the operation of
pressing, employ
a barrel supported
against the
pressure by a
mould of cast
iron-

Bramah's engine
the instrument for
applying the pressure

Tepidarium for
mellting and drawing
off Tallow
(before it has stood
long enough to putrefy
by a regulation
temperature.

Frigidarim , for
keeping it when
melted.

Keep Tallow thus
in different temperatures,
in &under
water, in which
case (according
to Haran's lecture
on Anatomical preparation)
in the
course of the year
it undergoes a
great change

Probably by combining
with the oxygen
of the Water
in which case what
becomes of the Hydrogene?
