of 166, Buchanan. Street,. in the City of Glasgow, North Britain, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her. Letters
Patent, bearing date the Fourteenth day of October, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Henry Johnson, Her special license that I, .the said. John Henry
Johnson, my executors, administrators, and assigns, or such others as I, the
said John Henry Johnson, 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, 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 "IMPROVE-
MENTS IN PRODUCING FIGURED PAPER TO BE USED IN TEACHING WRITING AND DRAW-
ING,"
a communication from Leon Louis Honore Bertou, of the firm of Messrs.
Bertou and Pottier, of Rue d'Hauteville, Paris, in the Empire of France,
upon the condition (amongst others) that I, the said John Henry Johnson,
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 Henry Johnson, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:-

page_text: The said Invention has reference to a peculiar system or mode of producing
on paper or other fabrics letters, figures, devices, or designs, to be used as a
means of conveying elementary instruction in writing or drawing. The
Invention consists in placing the paper to be operated upon with its face upon
a zinc plate, such plate having the described letters, figures, devices, or designs
engraved thereon either in relief or intaglio. A second metal plate, having a
smooth surface is then placed upon the back of the paper, and the whole is
passed through a copperplate printing machine, or subjected to pressure in any
other convenient form of press. The paper on being removed from the press
will be found to bear upon its surface an exact copy of the device engraved
upon the plate:
The mode of using these prepared sheets of paper consists in simply tracing
or following the lines or marks of the design or device with a lead pencil or
other marking instrument, whereby the elementary principles of writing.or
drawing will be learnt with ease and facility.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe, in conclusion, that I do not confine or restrict myself
to the precise details or arrangements which I have had occasion to describe
or refer to, as variations may be made therefrom without deviating from the
principles or main features of the said Invention; but what I consider to be
novel and original, and therefore claim as the Invention secured to me by the
herein-before in part recited Letters Patent, is,-
The system or mode of producing figured paper or other fabric to be used
in teaching writing or drawing, by subjecting the paper or fabric to be treated
to pressure between two metal plates, one of such plates having the required
letters, figures, devices, or designs engraved thereon, whilst the surface of the
other is perfectly smooth; the result of the operation being to leave on the
paper or fabrics traces to guide the learner by following the lines or designs
engraved.
In witness whereof, I, the said John Henry Johnson, have hereunto
set my hand and seal, this Sixth day of April, One thousand eight
L
J. HENRY JOHNSON. (L.S.)
