In order to avoid the
expence of feeding many
[Cattle] thro' the Winter,
as soon as the frost sets
in they generally Kill
cattle and Poultry sufficient
to last them till the return
of Spring. The carcasses are
buried in the Ground &
covered with a heap of
Snow, & as they are wanted
they are dug up, Vegetables
are laid up in the same
manner and they continue
very good throughout the
Winter.-
Longs Travels in
America 1791 p.85-
The weather being
more moderate I sent
my men to the Lakes
to look after the Nets
which had been under
the Ice a considerable
time the severity of the
Season not having allowed
us to examine them for
near a Month when to
our great mortification
They were found almost
rotten and not a single fish

Nicholson's Dicty Putrefaction.-
Every animal substance
exposed to the air at a
temperature above ten
degrees of Reamur
(Fahr 54 1/2) and
moistened with its own
serous humour putrefies
Word for wood from
Chaptal III 400.

Chaptal III 395.
Moisture is an indispensible
requisite to facilitate
putrifaction and any substance
may be defended
from this change by dry
compleatly drying it. This
was performed by Cazalet
and Villers of Bordeaux
by means of Stoves the Meat
thus prepared was preserved
for several years without
having contracted any
bad flavor.
The Mummy of this
sort from Teneriffe in
Trinity Colledge
Cambridge
The sands and light
pervious earth preserve the
bodies of men only by virtue
of the prosperity of exhausting
the juices and drying the
solids. From this cause
it is that intire caravans
have been discovered in
Arabia consisting of men
and Camels perfectly
preserved in the Sands
under which the impetuous
winds have buried them. ibid.
Mummies of this sort from
Teneriffe are kept in Trinity
Colledge Library Cambridge.

Chaptal III 274
The Contact of Air is the
2d necessary cause in the
putrifaction of Vegetables.
It is reported in the Ephirnnirides
of the curious
in Natural Phenomena
for 1787 (1687) that ripe
Cherries were preserved for
40 years by inclosing them
in a Vessel well luted and
placed at the bottom of a
well. 275. A certain
degree of heat is likewise
necessary the heat between
9 & 10 degrees (43 1/4 & 54 1/2
Fahrt) is sufficient to cause
decomposition. A greater
heat dissipates the humidity
dries the vegetable and
preserves it from putrifaction
Too little heat retards or
suspends it.

The temperature of Water
being much steadier much
less liable to sudden variation
than that of air.
