as follows (that is to say) :-
Our Invention which has reference to an improvement in the manufacture
of paper, by which the same is produced at less cost than by the means at
present in use consists in adding to the pulp or body of the paper, during the
process of manufacture, gelatine obtained or chemically prepared from bones,
the said gelatine being suitable for readily uniting with the pulp or body of
the paper, and used as a substitute for the ordinary sizing agents..

by the said John Louis Jullion and Gordon Pirie in the Great Seal
Patent Office on the 17th May 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
LOUIS JULLION and GORDON PIRIE, both of Stoneywood Works, Aberdeen,
North Britain, Paper Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of November, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Louis Jullion and Gordon Pirie, Her special licence that we
the said John Louis Jullion and Gordon Pirie, our executors, administrators,
and assigns, or such others as we, the said John Louis Jullion and Gordon
Pirie, our 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 IMPROVEMENT IN
THE MANUACTURE OF PAPER," upon the condition (amongst others) that we, the
said John Louis Jullion and Gordon Pirie, our executors or administrators, by
an instrument in writing under our or their or one of our or their hands and
seals, 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 we, the said John Louis Jullion and Gordon Pirie,
do hereby declare the nature of our 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):
Our Invention has reference to an improvement in the manufacture of paper,
whereby the same is produced at less cost than by the means at present in use,
and consists in adding to the pulp or body of the paper during the process of
manufacture, gelatine obtained from bones, the said gelatine being suitable
for readily uniting with the pulp or body of the paper when used as a substitute
for the ordinary sizing agents.
And in order that our said Invention may be more fully understood and
readily carried into effect, we now proceed to describe in detail the mode of
performing the same (that is to say.),

page_text: To produce the various descriptions of paper in accordance with our
improved manufacture, whereby paper of the usual character and quality may
be obtained at less cost than hitherto, we employ as a sizing agent the gelatine
obtained from bones or osseous matter, and we prefer to obtain this gelatine
by separating the constituent parts of bones or osseous matter by the action of
suitable solvents, as mentioned and referred to in Letters Patent granted to us
for the manufacture of the same, on the Seventh day of March One thousand
eight hundred and fifty-nine, No. 599; and on the Seventh day of September
One thousand eight hundred and fifty-nine, No. 2042, or the gelatine may be
obtained from bones in other ways, which may be known to chemists. This
gelatine is added, or mixed alone, or with other matters to the pulp in the
engine, or to either or both of the superficial surfaces of the web or fabric of
the paper by any of the means or methods at present employed or in use for
effecting the said operations.
Having now described the nature of this our said Invention, and the manner
in which the same is to be performed, we would have it clearly understood that
we do not claim as of our Invention the exclusive use of the substances or
processes herein-before mentioned, except when the same are employed in and
for the purposes of our said Invention, which we hereby declare to consist in
the employment of gelatine manufactured from bones or osseous matter as a
sizing agent for the manufacture of paper, as herein-before described.
In witness whereof, I, the said John Louis Jullion, on behalf of myself
and of the said Gordon Pirie, have hereunto set my hand and seal, this
Seventeenth day of May, in the year of our Lord One thousand eight
hundred and sixty.
