page_text: so as to prevent palpitation of the flesh, thoroughly bled, and imme-
diately skinned, opened, and cleansed. The carcase is then subjected to
a preservative bath for the purpose of closing the pores, the said bath
consisting of pure sugar mingled with alcohol and forming a glaze. The
meat thus prepared is placed in a case in a bed of melted fat of the same 5
kind of meat, and cooled to the temperature of the surrounding
atmosphere, whereupon the case with a vacuum formed therein is
soldered up. In this manner cutire carcases can be preserved for
transport in the condition of fresh meat.

in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is tọ
say :—
The object of our Invention is to preserve mutton or other ment in
bulk in its fresh uncooked condition. For this purpose we adopt the
following method or process:-The animal is suddenly killed by felling,
so as to prevent palpitation of the flesh, thoroughly bled, and imme-
diately skinned, opened, and cleansed. The carcase is then, without any
cutting up or cooking subjected to a preservative bath by plunging it
in the first place in purified phenol, one hundredth part by weight
dissolved in alcohol rectified to 72° of a scale in which water corresponds
to 0°, and absolute alcohol to 100°. The carcase having been withdrawn
from the bath is allowed to dry. It is then, in the second place,
plunged into a bath composed of sugar dissolved in alcohol and reduced
to the condition of caramel. When withdrawn from this bath it is
allowed to stand till the coating is formed over it. By this double bath
the pores of the carcase are closed, the fermenting principle is destroyed,
and a glaze is formed over its surface. The meat thus prepared is placed
in tin cases, preferably of cylindrical form, and of size suited to tho
The cases are filled in so as entirely to cover the meat with fat
of the same kind of meat, well purified by cooking with aromatic herbs,
and cooled down to about blood heat when poured into the cases. The
cases are thus entirely filled, or if they are not quite filled caro is to
be taken to form a vacuum in the space that may be left between the
contents and the cover, upon which they are soldered up by the blow
pipe.
