Thirtieth day of March, in the eighteenth year of His reign, give and grant
unto me, the said Humphrey Jackson, His especial licence that I, the
said Humphrey Jackson, during the term of years therein expressed,
should and lawfully might use, exercise, and vend, within England, Wales,
and Town of Berwick-upon-Tweed, my Invention of "AN INTIRE NEW
METHOD OF BEAUTIFYING AND PRESERVING THE NATIVE COLOUR OF ALL SORTS
OF WOOD, PARTICULARLY MAHOGANY, OR FURNITURE MADE THEREOF, IN A VERY
SUPERIOR MANNER TO ANY HITHERTO PRACTISED, BY MEANS OF A STAIN, VARNISH,
AND POWDER, WHICH POWDER. WILL LIKEWISE BE EXTREMELY USEFULL IN POLLISHING
AND SHARPENING ALL FINE STEEL-EDGED INSTRUMENTS;" in which said Letters
Patent there is contained a provisoe obliging me, the said Humphrey Jackson,
under my hand and seal, to cause a particular description of the nature of my
said Invention, and how the same is. to be performed, to be inrolled in His
Majesty's High Court of Chancery within four calendar months after the date
of the said recited Letters Patent, as in and by the same (relation being there-
unto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said provisoe I, the said
Humphrey Jackson, do hereby declare that my said Invention of an intire
New Method of Beautifying and Preserving the Native Colour of all sorts of
Wood, particularly Mahogany, or Furniture made thereof, in a very Superior

page_text: Manner to any hitherto practiced, by Means of a Stain, Varnish, and Powder,
which Powder will likewise be extremely Usefull in Polishing and Sharpening
all fine Steel-edged Instruments, is described in the manner following (that is
to say):
Take pummice stone and burnt allum, of each equal parts finely powdered,
true lapis calaminaris, tile, and green vitriol calcined to redness; of each half
a part finely powdered, mix them into a powder, and rub the wood with it with
a woollen cloth till it receives a good polish. N.B. They must be finely
levigated for edge tools. Then use the following stain-Take six pounds of
stick lac, boil it in three gallons of water till the colour is extracted, and strain
off the liquor, and add to it half a pound of madder root, boil it till it is
reduced to three quarts; take half a pound of cochineal, half a pound of
kermes berries, and four ounces of clean scarlet raggs; digest them in a glass
vessel with one gallon of spirit of wine, and two ounces of pearlash, dissolved
in half a pint of water till all the colour is extracted; strain and add the
decoction of stick lac to it. Lastly, add as much aqua fortis as will bring it
to a proper red colour, with which brush over the wood till it becomes of a
proper colour.
The Varnish. Take a pound of clear white amber, and half a pound of
gum copal, put them into a close vessel with six pounds of oil of nutts, half a
pound of spirit of turpentine, of oil of rosemary and lavender, each half a
pound; digest them in a sand heat till the oils become as thick as syrup, strain
for use; when clear, varnish the wood with a brush and let it dry.
In witness whereof I the said Humphrey Jackson have hereunto sett
