ealed the 22nd January 1878, and dated the 7th August 1877.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson at the
Office of the Commissioners of Patents on the 7th August 1877.
JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman. "IMPROVEMENTS IN PRESERVING ANIMAL, ALIMENTARY, AND OTHER
SUBSTANCES." A communication from abroad by François De Paula Marquez, of
Paris, in the Republic of France, Engineer.
This Invention relates to an improved process applicable to meat, game, poultry,
fish, eggs, skins of animals, and the like, and it has for its object the preservation of
such substances from deterioration, so as to enable them to be delivered to the
consumer in a condition of natural freshness.
In carrying out this Invention the alimentary substance (for example) is cut in
pieces if necessary, and plunged into a solution (heated by means of a water bath or
in any other suitable manner), and composed of water in which has been dissolved
a suitable proportion of gelatinous boracic fluoride, or any other similar substance.
This composition is obtained by intimately mixing fluoride of boron with gum and
sugar. The substance to be preserved is then taken out, and allowed to drain, and the
parts which have been touched with the knife are then covered with anhydrous
gelatinous boracic fluoride, that is to say, gelatinous boracic fluoride which has been
previously dried and pulverized. The operation is then terminated, and it only
remains to pack the substances or articles, either in order to store or warehouse them
on the spot, or to transport them to other places.
When it is desired to use meat prepared in this manner it is soaked in slightly
alcoholized water, and it will then be fit for sale. According to the requirements

or in cases of preserved meat, which may be soaked by the dealer himself before
being sold.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Henry Johnson in the Great Seal Patent Office on the 7th
February 1878.
JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman. "IMPROVEMENTS IN PRESERVING ANIMAL, ALIMENTARY, AND OTHER
SUBSTANCES." A communication from abroad by François De Paula Marquez, of
Paris, in the Republic of France, Engineer.
The said Invention relates to an improved process applicable to meat, game,
poultry, fish, eggs, skins of animals, and the like, and it has for its object the
preservation of such substances from deterioration, so as to enable them to be
delivered to the consumer in a condition of natural freshness.
In carrying out the said Invention the alimentary substance (for example) is cut
in pieces if necessary, and plunged for, say, about one minute into a solution (heated
by means of a water bath (bain marie), or in any other suitable manner), and
composed of water in which has been dissolved a suitable proportion of gelatinous
boracic fluoride, or any other similar substance. This composition is obtained by
intimately mixing fluoride of boron with gum and sugar. The substance to be
preserved is then taken out and allowed to drain, and the parts which have been
touched with the knife are next covered with anhydrous gelatinous boracic fluoride,
that is to say, gelatinous boracic fluoride which has been previously dried and
pulverized. The operation is then terminated, and it only remains to pack the
substances or articles either for the purpose of storing or warehousing them on the
spot, or for their transport to other places.
When it is desired to use meat prepared in this manner it is soaked in slightly
alcoholized water, and it will then be fit for sale. According to the requirements
of trade it may be delivered to butchers or other vendors in the latter condition, or
in the form of cases of preserved meat, which may be soaked by the dealer himself
before being sold.
Having now described and particularly ascertained the nature of the said Invention
and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to be novel and original, and
therefor claim as the Invention secured to me by the herein-before in part recited
Letters Patent is, the mode of preparing animal, alimentary, or other substances by
immersing the same in or causing them to absorb a solution of gelatinous boracic
fluoride, substantially as and for the purpose herein-before described.
In witness whereof, I, the said John Henry Johnson, have to this my Speci-
fication set my hand and seal, the Sixth day of February, One thousand
eight hundred and seventy-eight.
