PROVISIONAL SPECIFICATION left by the said Jacques Pierre
Henri Vivien at the Office of the Commissioners of Patents, with
his Petition, on the 15th December 1853.
I, JACQUES PIERRE HENBI VIVIEN, Manufacturer, of Paris, in the
5 Empire of France, and of 16, Castle St., Holborn (City), London,
do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN THE MANUFACTURE OF PAPER & PASTEBOARD" to be.
as follows:-
The application of yellow or dead leaves of all kinds of trees subjected
O to powerful pressure, so as to reduce them to cakes, then steeped in

page_text: lime water or other suitable solution, then washed and reduced to pulp
by the usual or any other suitable means, afterwards sized & bleached
in the usual way. This pulp may be used also in combination with
rags or other suitable material.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jacques Pierre Henri Vivien in the Great Seal
Patent Office on the 14th June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JACQUES PIERRE HENRI VIVIEN, Manufacturer, of Paris, in the Empire
of France, and of 16, Castle Street, Holborn (City), London, send
greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of December, in the
year of our Lord One thousand eight hundred and fifty-three, in
the seventeenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto I, the said Jacques Pierre Henri
Vivien, Her special licence that I, the said Jacques Pierre Henri
Vivien, my executors, administrators, and assigns, or such others as
I, the said Jacques Pierre Henri Vivien, my executors, adminis-
trators, 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 "CERTAIN IMPROVEMENTS
IN THE MANUFACTURE OF PAPER AND PASTEBOARD," upon the condition
(amongst others) that I, the said Jacques Pierre Henri Vivien, 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 Jacques Pierre Heuri Vivien,
do hereby declare the nature of my said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My improvements consist in the application of green, yellow, or dead
leaves of any kind of trees or shrubs to the manufacture of paper and
paste-board. For this purpose the leaves are gathered at the proper
time and season and subjected to powerful compression by means of
the hydraulic or any other suitable press, so as to reduce them into
cakes, which take up less room for storing and carriage. In order to
manufacture these cakes into paper or pasteboard I use the following
process:-First, the compressed leaves are steeped or lixiviated either
in lime water or in an alcaline solution, such as of carbonate of soda;
next the mass is washed and reduced into pulp by any suitable means
now in use. This pulp is then treated according to the quality of the
paper to be produced by applying to it the different operations of size-
ing and bleaching, which do not differ from those now in use and are
well understood by paper manufacturers. If it is thought desirable
the leaf pulp may also be mixed in variable proportions with pulp
made from rags or other substances now used for the manufacture of
paper and pasteboard.
Having thus described the nature of my Invention, and the manner
in which the same may be carried into effect, I wish it to be under-
stood that what I claim is, the manufacture of paper and pasteboard
from leaves of any kinds of trees or shrubs, as above described.
In witness whereof, I, the said Jacques Pierre Henri Vivien,
have hereunto set my hand and seal, this Ninth day of June,
in the year of our Lord 1854.
