1. Preservation in point of Substance
There are few substances but what, when exposed
as as in the natural course of things almost every thing is to the action of the a atmosphere
air, are subjected to certain air, undergoes some alterations which it is are
exicised understood to depend in great measure on upon the presence
of that element,[+] such for example are the participation [+] and which so far as that is the case may be prevented by its extraction and exclusion
of animal & vegetable substances in general the rancidity
of alteration which causes rancidity in oils the rusting of metals &c. any
such alterations which may be found really
to depend on the action of the air it
is plain may be prevented by the exclusion
of the air by the enclosing the substance in question
in as The practice of putting solid substances
in a substance which like fat is fluid in the degree
of heat at which it is applied seems to owe
its preserving quality in good measure to the exclusion of the air
by means of the fat, insinuating itself into all
the vacuities. Where If by an air pump or
otherwise the air can could be perfectly extracted were exhausted from all the
vacuities such vacuities and the subject are kept enclosed in an exhaust'd
chamber, it seems that it would be equally
well preserved. a degree of preservation as perfect
as in the former case may be expected.

4. The air in with or without the legh
which bodies are are found to exposure sooner or later subject in point
of colour are known to result from the action of the air.
An exhausted chamber affords the means of preserving them
from all such changes for any length of time, care being taken
to exclude the light, where the presence of that element also
is found to influence the result # This tarnishing, fading and other such changes of colourinjuries may be prevented [To p.7]
