make, use, exercise, and vend, within that part of the Kingdom of Great
Britain called England, the Dominion of Wales, and Town of. Berwick-
upon-Tweed, and also in His Majesty's Plantations and Colonies abroad,
my Invention of "MAKING A METAL OF THE COLOUR AND IN ALL RESPECTS
RESEMBLING GOLD;" in which said Letters Patent is contained a proviso
obliging me, the said Richard Dovey, under my hand and seal, to cause a
particular description of the nature of the said Invention, and in what manner

"NOW KNOW YE, that in compliance with the said provisoe, I, the said
Richard Dovey, do hereby declare that my said Invention of Making a Metal
of a Colour and in all respects Resembling Gold, and greatly varies from
any other metal hitherto invented, is performed in the following manner (that
is to say):

page_text: The materials of my new Invention of Making a Metal of the Colour and in
all respects Resembling Gold, are made of different compounds as follows:-
One ounce and a half of copper; a two pennyweight and four grains and a half
of grain tin; a two pennyweight and half a grain and quarter of a grain
of zink or spelter; half a grain of antimony; half a grain of red lead; half a
grain of mangonize oar; half a grain of crocus martus oar, which are made
use of as follows:-First the copper is put into a black lead melting pot, and
then put into an air furnace, and then melted, and when in full heat then the
grain tin is put into the hot copper to purify the copper and close up the pores,
which hardens it; then give it half an hour's heat again to purify it;
then put in the zink to give it a yellow tinge; about ten minutes after throw
in the antimony, as described, together with the red lead and mangonize oar
and crocus martus, which is lapp'd up in paper before thrown into the furnace,
which continues in the pot about five minutes, and then pour it off into an
ingott. Then it is fit for manufactoring into diverse articles by flatting or
remelting for buckles, sleeve buttons, watch cases, candlesticks, &c., and the
second time of melting makes it better than the first for use.
In witness whereof, I, the said Richard Dovey, have hereunto set my
hand and seal, the Ninth day of March, in the fourteenth year of the
reign of His Majesty King George the Third, &c., and in the year
of our Lord One thousand seven hundred and seventy-four.
Inrolled the Tenth day of March, in the year above written.
