the County of Middlesex, Veterinary Surgeon, for the lnvention of
" IMPROVEMENTS IN EFFECTING THE PRESERVATION OF ANIMAL SUBSTANCES,
AND IN THE PRODUCTION AND EMPLOYMENT OF A NEW ANTISEPTIC."

Sealed the 5th July 1870, and dated the 7th January 1870.
PROVISIONAL SPECIFICATION left by the said John Gamgee at the
'Office of the Commissioners of Patents, with his Petition, on the
7th January 1870.
'
I, JOHN GAMGEE, of Queen's Road, Bayswater, in the County of
Middlesex, Veterinary Surgeon, do hereby declare the nature of the said
PRESERVATION OF ANIMAL
Invention for "IMPROVEMENTS IN EFFECTING THE
SUBSTANCES, AND IN THE PRODUCTION AND EMPLOYMENT OF A NEW ANTISEPTIC," to
be as follows:-
This Invention relates, firstly, to an improved method of effecting the
preservation of animal substances, sueh, for example, as horn, hides,
bones, flesh, fat, fish, and other products, and consists in the employ-t
ment for such purposes of what is known as the chloride of aluminum,
[Price 8d1

page_text: or that product which is obtained either by effecting the solution of
alumina in hydrochloric acid, or by other known means.
This Invention relates, secondly, to the employment of such before-
mentioned chloride of aluminum as an antiseptic.
In carrying out the first part of this Invention the animal substances
are either to be immersed or impregnated with a solution of chloride of
aluminum; the strength of which solution will vary according to the
quality and condition of the substances under treatment, but I have
found that a solution of about 1100 S. P. G. will give in general good
results.
I carrying out the second part of this Invention I employ the
chloride of aluminum as an antiseptic, either alone or in conjunction
with a porous material, such, for example, as charcoal, either of which
preparations may be employed as antiseptics in a manner similar to that
now adopted either when carbolic acid or other antiseptic agent is
employed. Instead of employing chloride of aluminum alone for the
purposes herein-before mentioned it may be advantageously used in
conjunction with metallic, alkaline, earthy, or alkaline chlorides, such,
for example, as the chlorides of iron, lime, and soda, or mixtures of
the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
"
filed by the said John Gamgee in the Great Seal Patent Office on
the 7th July 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GAMGEE, of Queen's Road, Bayswater; in the Courty of Middlesex,
Veterinary Surgeon, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of January, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Gamgee, Her special license that
I, the said John Gamgee, my executors, administrators, and assigns, or
such others as I, the said John Gamgee, my executors, administrators,
or assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,

page_text: 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 EFFECTING THE
PRESERVATION OF ANIMAL SUBSTANCES, AND IN THE PRODUCTION AND EMPLOYMENT
OF A NEW ANTISEPTIC," upon the condition (amongst others) that I, the
said John Gamgee, my executors or administrators, by an instrument
in writing under my hand and seal, 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 months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said John Gamgee, do hereby declare
the nature of my 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 relates, firstly, to an improved method of effecting the
preservation of animal substances, such, for example, as horn, hides,
bones, flesh, fat, fish, and other products, and consists in the employ-
ment for such purposes of what is known as the chloride of aluminum,
or that product which is obtained either by effecting the solution of
alumina in hydrochloric acid, or by other known means.
This Invention relates, secondly, to the employment of such before-
mentioned chloride of aluminum as an antiseptic.
In carrying out the first part of this Invention the animal substances
are either to be immersed in or impregnated with a solution of chloride
of aluminum, the strength of which solution will vary according to the
quality and condition of the substances under treatment, but I have
found that a solution of about 1100 specific gravity will give in general
good results.
In carrying out the second part of this Invention I employ the
chloride of aluminum as an antiseptic, either alone or in conjunction
with a porous material, such, for example, as charcoal, either of which
preparations may be employed as antiseptics in a manner similar to that
now adopted either when carbolic acid or other antiseptic agent is
employed. Instead of employing chloride of aluminum alone for the
purposes herein-before mentioned it may be advantageously used in
conjunction with metallic or alkaline chlorides, or chlorides of the

page_text: alkaline earths, such, for example, as the chlorides of iron, lime, and
soda, or mixtures of the same.
Having now described and particularly ascertained the nature of my
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
novel and original, as secured to me by the herein-before in part recited
Letters Patent is, the employment of the chloride of aluminum as a
preservative of animal substances and as an antiseptic, either when
employed alone or in conjunction with metallic or alkaline salts, or
salts of the alkaline earths, or mixtures of the same, substantially as
herein-before described.
•
In witness whereof, I, the said John Gamgee, have to this my
Specification set my hand and seal, the Seventh day of July One
thousand eight hundred and seventy.
JOHN GAMGEE. (L.S.)
