Scaled the 2nd March 1875, and dated the 5th September 1874.
PROVISIONAL SPECIFICATION left by the said Henry Bolleter at the
Office of the Commissioners of Patents, with his Petition, on the.
5th September 1874.
I, HENRY BOLLETER, of Foley Street, in the County of Middlesex, do.
hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MEANS. AND PROCESSES EMPLOYED FOR TREATING AND PRESERVING ANIMAL.
SUBSTANCES FOR USE AS FOOD," to be as follows:-
-
This Invention has for its object improvements in the means and pro-
cesses employed for preserving animal substances for use as food. For
this purpose the gelatine in the meat to be preserved is solidified by-
:

page_text: means of a compound consisting of two-thirds common salt and one-
third nitre, which is spread over the surface of the meat or animal
matter in the proportion of about half an ounce or thereabouts to each
pound of solid meat.
The meat or animal matter thus treated is arranged in layers upon
perforated plates or wire gauze and placed in vessels arranged in an oven
or chamber to which heat is applied by steam or otherwise in order to
subject the animal substances thus treated (for about ten or fifteen
minutes) to a temperature of 212 degrees Fahrenheit or thereabouts,
according to the nature or quality of the meat so treated.
The meat thus treated is further proserved by enclosing it in vessels
hermetically sealed, as is well understood.
OF COUCH LOTU.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BOLLETER, of Foley Street, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of September, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Henry Bolleter, Her special license that I, the
said Henry Bolleter, my executors, administrators, and assigns, or such
others as I, the said Henry Bolleter, my executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE MEANS AND
PROCESSES EMPLOYED FOR TREATING AND PRESERVING ANIMAL SUBSTANCES FOR USE

page_text: AS FOOD," upon the condition (amongst others) that I, the said Henry
Bolleter, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and
in what manner the-same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
.
NOW KNOW YE, that I, the said Henry Bolleter, do hereby declare
the nature of the said Invention, and in what manner. the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :—
This Invention has for its object improvements in the means and pro-
cesses employed for preserving animal substances for use as food. For
this purpose the gelatine in the meat to be preserved is solidified by
means of a compound consisting of two-thirds common salt and one-
third nitre, which is spread over the surface of the meat or animal
matter in the proportion of about half an ounce or thereabouts to each
pound of solid meat.
The meat or animal matter thus treated is arranged in layers upon
perforated plates or wire gauze and placed in vessels arranged in an oven
or chamber to which heat is applied by steam or otherwise in order to
subject the animal substances thus treated (for about ten or fifteen
minutes) to a temperature of 212 degrees Fahrenheit or thereabouts,
according to the nature or quality of the meat so treated.
The meat thus treated is further preserved by enclosing it in vessels
hermetically sealed, as is well understood.
In carrying out my improvements I find it desirable to reduce the
limbs and other bony portions of an animal to an extract of meat, as is
well understood, and I introduce about one ounce and a half of such
extract to each pound of meat preserved in accordance with my improve-
ments into the vessels containing the preserved meat.
Having thus described the nature of my improvements and the manner
of performing or carrying the same into practice, what I claim is the
improved means and processes employed for treating and preserving

page_text: animal substances for use as food, substantially in the manner and for
the
purposes herein-before described.
In witness whereof, I, the said Henry Bolleter, have hereunto set
my hand and seal, this Third day of March, in the year of our
Lord One thousand eight hundred and seventy-five.
HENRY BOLLETER. (L.s.)
