Lane, in the County of Middlesex, for the Invention of "AN
IMPROVED VEGETABLE EXTRACT FOR CULINARY PURPOSES."-A communi.
cation from abroad by Gustave de Villepoix, Apothecary, and

PROVISIONAL SPECIFICATION left by the said Alexander Melville
Clark at the Office of the Commissioners of Patents, with his
Petition, on the 18th February 1868.
I, ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the
County of Middlesex, do hereby declare the nature of the said Inven-
tion for "AN IMPROVED VEGETABLE EXTRACT FOR CULINARY PURPOSES," to be
as follows:-
This Invention consists in the preparation of an aromatic liquid or
extract from vegetables and condiments used for culinary purposes.
The object of this extract is to offer to consumers of Liebig's extract

page_text: of meat, for instance, or other similar preparations. the means of
preparing a soup on the shortest notice possessing all the flavour of
the best stews or mixed soups. This extract, like Liebig's and other
meat extracts, is prepared in a highly concentrated state, in which
-condition it may be kept for any length of time. It will be understood
that the nature of the extract and proportions of the vegetables and
condiments may be varied at will, the following being merely an example
of the mode of preparation:-In a suitable tinned copper, still, or other
.culinary utensil, furnished with a double bottom and containing, say,
-sixteen gallons of water. I nut

previously supplied with about twenty-seven pounds of common salt
and eighteen pounds of white sugar. These substances serve to preserve
all the flavour of the preparation and at same time prevent fermen-

aromatic liquid containing the salt and sugar in solution with register
thirty degrees of Beaumé's areometer. The object of adding salt to
the first preparation is to raise the boiling point of the water in order
to permit of the distillation of the essential oils of the ingredients

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alexander Melville Clark in the Great Seal
Patent Office on the 13th. August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of February, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alexander Melville Clark, Her special
licence, that I, the said Alexander Melville Clark, my executors,
administrators, and assigns, or such others as I, the said Alexander
Melville Clark, 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 "AN IMPROVED VEGETABLE EXTRACT FOR CULINARY PURPOSES,"
a communication to me from abroad by Gustave de Villepoix,
Apothecary, and Joseph François Bonnaterre, Civil Engineer, both of
29, Boulevart St.. Martin, Paris, upon the condition (amongst others)
that I, the said Alexander Melville Clark, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of
their hands and scals, should particularly 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 monthis next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Alexander Melville Clark,. 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 (that is to say) :—
This Invention consists in the preparation of an aromatic liquid or.
extract by the distillation of vegetables and condiments used for culinary.
purposes. The object of this extract is to offer to consumers of Liebig's
extract of meat, for instance, or other similar preparation, the means

page_text: of preparing a soup on the shortest notice possessing all the flavor of
the best stews or mixed soups. This extract, like Liebig's and other
meat extracts, is prepared in a hightly concentrated state, in which
condition it may be kept for any length of time.
It will be understood that the nature of the extract and the pro-
portions of the vegetables and condiments may be varied at will, the
following being merely an example of the mode of preparation :-In
a suitable tinned copper, still, or other culinary utensil, furnished with
a double bottom and containing sixteen gallons of water, I put of
:
Common salt about 4 pounds.
Turnips
40 pounds.
เ
Leeks
18 pounds.
Onions
1 pounds.
Celery
6 pounds:
Parsley
1 pounds.
Cloves
Garlic
200
8 heads.
The above mixture is then distilled over a slow fire until reduced
by about seven gallons. One of the characteristic points in the
preparation of this extract is that the aromatic liquor is then
collected in a vessel previously supplied with about 27 pounds of
common salt and eighteen pounds of white sugar. These substances
serve to preserve all the flavor of the preparation and at same time
prevent fermentation. When the above distillation has produced about
seven gallons the aromatic liquid containing the salt and sugar in a
_solution will register thirty degrees of Beaumé's arcometer. The object
of adding salt to the first preparation or macerating liquid is to raise
the boiling point of the water in order to permit of the volatilization or
distillation of the essential oils containing the aroma of the ingredients
employed.
Having described the nature of this Invention, and the manner of
performing the same, I declare that what I claim as the Invention to
be protected by the herein-before in part recited Letters Patent is, the
preparation of a vegetable extract from the ingredients before enume-
rated to be applied for culinary purposes as herein-before described,
the chief features of the Invention consisting, first, in the decoction of
the materials in water containing salt in solution for the purpose of
raising its boiling point and facilitating the distillation or extraction

page_text: of the aroma and volatile principles of the vegetables; secondly, the
collection and condensation of the said volatile principles or aroma
in a saline solution, all as herein-before described.
In witness whereof, I, the said Alexander Melville Clark, have
hercunto set my hand and seal, this Thirteenth day of August,
in the year of our Lord One thousand eight hundred and sixty-
eight.
