12 Dec 1808 Frigidarium factor

To keep 'for a constancy'
the conservative temperature
in the atmosphere
of the frigidarium seems
nearly hopeless; at
least in the small experiment

But neither is it desirable.

2

For the it was the
Balneum that was in
relied on from the first:
and the avantage of this
is that by reason of
its simplicity, it forms
a most convenient principle
for a patent

3

On this consideration
it seems to be settled
(12 Decr 1808) that the
mode of giving light
may and must be by
a lamp carried in the
hand: matters being so
ordered that the time
sojournment may be as
short as possible.

4

One Vessel of each
article to be filled up
with water

As any one article
would in case of putrefaction
contaminate
whole atmosphere,
better not place any
article in atmosphere,
but in Vessels closed
with water stopples
no; with but with cork
stopples

5

A thatched hood
to be made - to move
on wheels - to shade
the add adit from
the sun

6

To ascertain the heat
produced by each pumping
(viz. once a day)
take out from the atmosphere two thermometers
one immediately
before begininning to pump,
the other a little after the
pumping is finished.

Vessels 12 decr 1806

For the Balneum

1. Phials and gooseberry
bottles - with
cast iron saucers to
sink them.

2. Hooped Barrels

3. Each bottle with
its Saucer to have a
cork for a buoy, with
the day of its Introduction
on a label, space
being allowed to insert
day of extraction

4 For the Table and
Shelves in the atmosphere.

1. three used Glass each
with a cap to stand in
an external trench holding
a water Stopple

1. On the Sh Table 2
See Col 1 No 6

2 On the highest shelf - 1

2. In the Frigidarium
Balneum

3. In the Anti Frigid.
Balneum

N.B. Cheap thermometer at
the shops in Holborn

9.

Reckoning the glass at
the same weight as water,
the iron saucer should
weigh full as much
as half the water which
the phial or bottle contains

For casks, the weight
should be greater.

Preservanda in
balneo 12 decr 1808

1. Milk in the phials

2. Chopped cabbage and
Cale in the gooseberry
bottles to represent
peas, beans and french
-beans

3. Ox and Calves Hearts
in the Barrels, to represent
Venison and Game

4. Sprats and Herrings
in the Gooseberry bottles
to represent other fish

5. Untill the fruit season
arrives the chopped
cabbage &c may afford
some ground of expectation
in regard to fruits.

6. If any of the existing Grasses
keep long enough they
will serve still better.

7 Pears, if the Cabbage
is found to keep

8. In a Gooseberry bottle
a Rabbit cut upin readiness for
a Curry.

To carry the experiment
to its full length the
course might to continue
a whole twelve month: because
in some instances
(ex.gr..) tender fruits, they
ought to be kept
months to come in li
of early ones.

12

On this account it
would even be of use,
with a view to fruits and
legumes ex. gr. strawberries
and green peas to
continue the frigidarium
in use for a twelve month
afar In depositing of an
assortment of preservation
of these several kinds.
But of any other articles
are present in the meantime
to keep the whole twelve month

15

Cheap spirit thermometers
to b hav to be bought to
with two points fixed
to be graduated on a
board scale - To ascertain
their correctness to
be placed with a good
Mercurial Thermometer
in the same pan efluates

16

To ascertain degree
of uniformity as between
the cheap and correct
thermometers, try them
all together, first in water
of the temperature as
drawn, then with waterthe same
heated by asion of
boiling water

17

In this way a comparison
might also be
made as between air-
thermometers and ordinary
do.

12

twelve months the or even
a less time, the building
of the commercial Frigidarium
need not wait.

13

For the indication
of the changes, if any,
undergone each day
the melt being the most
changeable which of any
may suffice:

14

unless it be shew'd
worth while to add some
cheap fish and meat
to be taken out in
from 2 to 7 days.
