HUDSON, of Cheapside, in the City of London, Paper Hanger, send greeting.
WHEREAS, His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Ninth day of December, in the
fifty-second year of His reign, did give and grant unto me, the said John
Hudson, my executors, administrators, and assigns, His special licence, full
power, sole privilege and authority, that I, the said John Hudson, my execu-
tors, administrators, and assigns, should and lawfully might, during the term
of years therein expressed, make, use, exercise, and vend, within that part of
His Dominion called England, Wales, and the Town of Berwick-upon-Tweed,
my
Invention of "A COMPOSITION FOR PRINTING OR PAINTING ON PAPER, LINEN,
STUCCOED WALLS, AND BOARDING, FOR THE PURPOSE OF ORNAMENTING THE WALLS
AND CEILINGS OF Rooms;" in which said Letters Patent there is contained a
proviso, obliging me, the said John Hudson, by an instrument in writing under
my hand and seal, to cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be inrolled in
His Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said recited Letters Patent, as in and by the
same (relation being thereunto had) may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Hudson, do hereby declare that my-said Invention of a composition, and
the manner in which the same is to be used, are described as follows:-
The composition consists of a powder consisting of fine sand, tale, leaf gold,
or sprecles, and pulverized flake glass, rendered to certain degrees of fineness
in the following manner :-To prepare the flake glass for use, spread it thinly
over a sheet of smooth paper, roll the paper and glass round a cylinder of about
two inches diameter, unroll. the same carefully, so as to leave it spread out as
at first, then roll it up again from left to right repeatedly, until it is of that
degree of fineness required. This method is to preserve the brilliancy which
bruising would injure, but when mixed with colour, as hereafter explained, this
trouble need not be taken. Various and regular degrees of fineness of the
materials may be obtained by sifting them through woven brass wire sieves.
The sand is that usually termed silver or writing sand which I use for shadow-
ing, and where the glass and tale alone would be too brilliant for the required
effect. The foregoing materials, or any part of them, according to the degree
of brilliancy required, are then mixed with size and body color of such tint as
may be required, then dried and rolled with the cylinder, ready for use. The
use of the size and body colour is to prevent the composition appearing too
conspicuous for daylight; but when that is not an object, and great brilliancy
is required, the materials may be used without this preparation, but as described
in the first section. The gold leaf is pulverized by grinding it with about two
ounces of flake glass to one leaf of gold.
Method of colouring or grounding a piece of paper intended to be printed
on, or to be used for stiles, fillets, and mouldings for pannelling. In addition
to the usual implements used in paper staining, erect over the colouring table
a square or oblong box or sieve, at the height of about eight feet, to move in
a groove the length of the table; and to prevent too large a proportion of the
composition falling on any one part, affix a case at each end to receive the
seive, the size of which should be about twenty-three inches over (the usual
width of paper used for hanging), with very fine woven brass wire for the
bottom, and to run in the groove on four small wheels, by means of a cord
fastened to it and passed into the case, a pulley being fixed in the centre of
the side for drawing the cord through, and the same for repassing the scive
to the opposite end; at the bottom of the groove small slips of leather, about
one-sixteenth of an inch thick, glued at the distance of about two inches from
each other, which will cause the box or sieve to shower out the composition
in regular quantity.

sieve of the same description as for grounding is flung over the printing table,
with a cord or chain and balance weight, similar to that used for lamps, to pull
down as often as wanted to sift over the composition, which is usually every
three prints.
For painting the side of a room, pannel, or stiles in distemper or body colour
or oil colour. When the colour intended to be used is just about to set in a
jelly, that the brilliancy may be rendered durable, sift in half a pint of the
materials (chiefly tale) to a gallon of colour, of stirring it constantly, which
should also be done while it is used, when a greater degree of brilliancy is
required. While one person commences colouring with the above preparation
from the bottom to the top, a second is to throw on the composition or any
part of it with a sieve, made of woven brass wire, in form like a wooden
mallet, one end to unscrew to receive the composition.
In witness whereof, I, the said John Hudson, have hereunto set my hand
and seal, this Seventh day of February, in the year of our Lord One
