Preservation by Temperature Cold Conservatory

In contriving the
preparatory experiments
keep an
eye to the practice
in the great, so as
not to aim at
greater degrees of
nicety than can
be made sure of
in common practice
- unless for
the sake of settling
principles.

When water (hot
or cold) is let into
the Balneum in
order to regulate
the temperature
by making up
for any unite
unintended change
produced in it
it should be let
in in driops rather
than in a mass
ex.g. by spouting
thro' a rose over
the cock or by
droppong thro'
a cullender &c

Ship Conservatory

By means of the
Double-Vessels bounded
bad-conducting
Vessels Ice might
probably be carried
to the E. Indies
and back again
without melting
more than required
beyond the power
of keeping the included
Balneum
at the non-fermenting
temperature.

The great demand
for cold would be
to reduce the goods
themselves in the first
instance to within
the non-fermenting
temperature.

The possibility is
means of managing
the Ship Conservatory
might
be previously
established by experiments
on land.
