Birds and Hares
&c might perhaps
go into putrefaction
with their own heat
if taken in on a
hot day, unless
cooled by water.
Observe the increase
of temperature produced
in the water
by each cooling,
and reduce it
by putting in ice.
After standing
a suffucient time
in the water to cool, the article
might then
be hung up to
drain, either in
the Cooling room
or the Frigidarium
itself
To keep down
the temperature
in the Frigidarium
stow ice in a horizontal
racks as
high up as it
can be stowed. The air below
in proportion as it
is heated by the bodies
of the operators
&c will rise
to the top and melt
the ice, which as
it melts will drop
down and cool the
air below.

Thermometers
Fluid red coloured
spirit.
Tube large & long
with a long scale
but short -say
20 belowabove &
to to 80.
White board with
black figures.
Thermometer liquor
the more sensible
the better and
as no heats above
80 will require to be
indicated, the only
objection to spirits
seems out of the
question here.
Thermometer that
shows the highest
rise & lowest fall

Mercury & Alcohol
with a floating
