WHEREAS Her most Excellent Majesty Queen Victoria, by Her

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 "IMPROVEMENTS IN THE PROCESS OF REPRODUCING ON WOOD ALL ENGRAVINGS
THROUGH AQUAFORTIS," upon the condition (amongst others) that we, the
said Alexandre Paténe, Felix Bardoux, and Gustave Jurie, our executors
or administrators, by an instrument in writing under our, 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

page_text: Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that we, the said Alexandre Paténe, Felix Bardoux,
and Gustave Jurie, 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 :-
The object of the present. Invention is to accurately reproduce on wood,
engravings, woodcuts, or carvings obtained by the photo-lithographic
process by the aid of aquafortis or azotic acid.
The following is the mode of procedure:-Having previously varnished
the article to be operated on, whatever it may be, and on which it is
desired to imprint the engraving, woodcut, or carving, such engraving
or woodcut, as the case may be, is steeped in aquafortis or nitric acid,
and is then applied to the varnished part and hot pressed, after which
it is allowed to cool, when it is finally washed with clear cold water
and then allowed to dry. The engraving, woodcut, or carving is thus
accurately reproduced and is perfectly indelible.
It is obvious from the description of the Invention that it is invaluable
as a means of ornamenting various articles, such as work boxes, dressing
cases, pieces of furniture, and other similar objects.
Having thus described our Invention, what we claim and desire to
secure by Letters Patent is, the process of reproducing prints, en-
gravings, woodcuts, carvings, or sculpture on wood in the manner and
for the purposes herein set forth.
In witness whereof, we, the said Alexandre Paténe, Felix Bardoux,
and Gustave Jurie, have hereunto set our. hands and seals, this
Twenty-seventh day of January, in the year of our Lord One
thousand eight hundred and seventy.
