PROVISIONAL SPECIFICATION left. by the said Charles Emile
Pommier at the Office of the Commissioners of Patents, with his
Pétition, on the 14th September 1868.
1, CHARLES EMILE POMMIER, of 2, Rue Sainte Appoline, l'aris, in
the Empire of France, Chemist, do hereby declare the nature of the
said Invention for "AN IMPROVED SIZE OR COMPOUND FOR TREATING OR SIZING
PAPER," to be as follows:-
My improved size or compound consists of a solution of sulphate of
alumina mixed with a solution of resinous soap, from which obtain a
precipitate which is the resinate of alumina; this precipitate when
washed, drained, and pressed forms the size or compound constituting
my Invention.

page_text: To dissolve a hundredweight of resin I employ about a quarter of a
hundredweight of salt of soda. The resinous soap thus obtained is pre-
cipitated from its soda solution by a solution of the sulphate of alumina,
the proportions of which latter are immaterial.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Emile l'ommier in the Great Seal
Patent Office on the 13th March 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
EMILE POMMIER, of 2, Rue Sainte Appoline, Paris, in the Empire of
France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of September, in the
year of our Lord One thousand eight hundred and sixty-eight, in
the thirty-second year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Charles Emile Pommier,
Her special licence that I, the said Charles Emile Pommier, my
executors, administrators, and assigns, or such others 'as I, the said
Charles Emile Pommier, 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 SIZE OR COMPOUND FOR TREATING
SIZING PAPER," upon the condition (amongst others) that I, the said
Charles Emile Pommier, my executors or administrators, by an in-
strument in writing under my, or their, or one of their hands and
seals, 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 1, the said Charles Emile Pommier, do hereby

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say:-
My improved size or compound consists of a solution of sulphate
of alumina mixed with a solution of resinous soap, from which I obtain
a precipitate which is the resinate of alumina. This precipitate when
washed, drained, and pressed forms the size or compound constituting
Ipy Invention. I call the new size or compound aluminocolle."
Dy
The advantage of the compound is to provide paper manufacturers
with a material not liable to the irregularities heretofore incident to
the preparation of a compound subject to changes in its manufacture
which is based on the combination of several elements always subject to
irregularity in manufacture.
To dissolve a hundredweight of resin I employ a quarter of a hundred-
weight of salt of soda. The resinous soap thus obtained is precipitated
from its soda solution by a solution of the sulphate of alumina, the
proportions of which latter are immaterial.
And having now described the nature of ny said Invention, and
in what manner the same is to be performed, I declare that I claim
the improved size or compound for treating or sizing paper herein-before
described.
In witness whereof, I, the said Charles Emile Pommier, have
hereunto set my hand and seal, this Tenth day of March, in
the year of our Lord One thousand eight hundred and sixty-
nine.
