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

of Spring. The carcasses are

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

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.

3 Chaptal III 274 The Contact of Air is the 2d necessary cause in the putrifaction of Vegetables. It is reported in the Ephirneridus 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. 4 The temperature of Water
