A bottle capable of containing three pints was filled with water, and
inverted into a bason of the same; a tube which communicated with
another bottle, in which was an effervescing mixture of chalk and oil
of vitriol, was then introduced into the mouth of the former, and a
stream of fixed air continued, till the whole of the water was driven
out by it. A piece of the above-mentioned putrid beef, fastened by a
string to a cork, was conveyed into the bottle, which was corked before
it was taken out of the water. The beef, after having been suspended in
this atmosphere of fixed air for thirteen hours, was very considerably,
though not entirely sweetened. _But the air in the bottle seemed
to have acquired all the putrid smell of which the flesh had been
deprived._ Another slice of the same beef was not at all sweetened by
exposure, during the same time, to the open air.
