TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEX-
ANDER OGG, of Glasgow, in the County of Lanark, North Britain, Shoemaker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of August, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alexander Ogg, Her special license that I, the said Alexander Ogg,
my executors, administrators, and assigns, or such others as I, the said Alex-
ander Ogg, 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 "A NEW COMPOSITION APPLICABLE
TO THE CEMENTING OF LEATHER," upon the condition (amongst others) that I,
the said Alexander Ogg, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, 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 Alexander Ogg, 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):-
My Invention of "A New Composition applicable to the Cementing of
Leather" consists in combining the following materials in or about in the
following proportions, thereby forming a cement applicable to the purpose of
joining leather to leather (viz.) :-One quarter of an ounce of asphaltum, one
ounce of gutta percha, one quarter of an ounce of resin. These materials are
dissolved in five ounces of bisulphate of carbon.
In order, however, that my Invention may be fully understood and readily
carried into effect, I will describe the best mode of manufacturing the above
composition with which I am acquainted, but to which I do not confine
myself.
I take a bottle containing two ounces and a half of bisulphate of carbon, to

page_text: which I add one-half of an ounce of gutta percha, one-eighth of an ounce of
common resin, and one-eighth of an ounce of asphaltum, and leave this
mixture until these materials or ingredients have become dissolved by the
bisulphate of carbon. I then take another bottle containing two ounces and
a half of bisulphate of carbon, to which I add one-half of an ounce of
gutta percha, one-eighth of an ounce of common resin, and one-eighth of an
ounce of asphaltum. These materials or ingredients, being left to become
dissolved by the bi-sulphate of carbon, are afterwards mixed with the con-
tents of the first bottle. The whole composition thus formed becomes ready
for use in the course of a few hours, sooner or later, according to the state of
the atmosphere at the time when it is made. It should be kept in a bottle
well corked.
Having thus described the nature of my Invention, and in what manner
the same is to be performed, I would have it understood that I do not mean
or intend to confine myself to the exact proportions of the materials or
ingredients above stated, nor to the mode of combining or amalgamating them
as described; but what I do claim as of my Invention is, the manufacture
of the composition by combining or amalgamating the materials or ingredients
as described.
In witness whereof, I, the said Alexander Ogg, have hereunto set my
hand and seal, this First day of February, in the year of our Lord
One thousand eight hundred and fifty-five.
FRED W RIDPETH,
Witness.
(L.S.) ALEXANDER OGG.
