Hot or Cold?

The Hot or Cold
method which the
most advantageous

The cold method
leaves the substances
unaltered.

It will also be
cheaper, requiring
nothing but space
filled with Ice

The Hot can be
preferable only
at Sea, not then
but on the supposition
that Ice sufficient
for the cold
method can not be
preserved at all,
or at least not without
such an expence
in vessels as would
render this method
dearer than the other

The Hot can serve
only for Fish and
Flesh. not for fruits:
or at least the fruits
in this method would
different from fresh
fruit.

Hard pressure
another means of
preservation - perhaps
self-sufficient
where flavour is not
required. Ex.g.

1. Fish.

Inpurment, Brama

THus Bottles may be corked in vacuo by screwing permission not being applicable. See Collins, ??? for scaling with wafers. Vessels For experiment & before the preservative affect of the temperature are fully ascertained, under every degree of temperature,, & in the instance oof every sort of SUnbject, Glass 1. That the changes of any may be exposed to constant observation. 2. That the goodness of the Subject may be ascertainable, previously to its being taken out for use Afterwards Barrels as being the cheapest close Vessel.

Desiderata

1. Best means of
preserving the requisite
temparature

2. Best means of vindicating
it.

3. Temperature propse
for each Subject
or class of subjects.

cheapest method of
constructing thermometers

The graduation
may be performed
on the glass itself,
without any plate

the purpose

4. Effect of each
time of entrance
upon the conservatory.

This with depend
upon the

1. The quantity of
hotter air let in
each time

2. Its superiority of
temperature.

5. Effect of a given
quantity of ice
upon the quantity
of water in the
Bath

Pird for the Thermometer -
Alcohol
the best for these low
temperatures- More
sensible than Mercury,
& when coloured
more visible.
