WHEREAS His most Excellent Majesty King George the Third, by His

Thirty-first day of October last, did give and grant unto the said Charles
Watt, his executors, administrators, and assigns, especial licence, full power,
sole privilege and authority, that the said Charles Watt, his executors, adminis-
trors, and assigns, by himself and themselves, or by his and their deputy
or deputies, servants or agents, or such others as the said Charles Watt, his
executors, admors, or assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term of years thercin
expressed, should and lawfully might make, use, exercise, and vend, within
that part of the United Kingdom of Great Britain and Ireland called
England, the Dominion of Wales, and the Town of Berwick-upon-Tweed, and
also in the Colonies and Plantations abroad, the Invention or Discovery of the
said Charles Watt of "GILDING AND PREPARING QUILLS AND PENS BY MANUAL
LABOUR AND CHEMICAL OPERATIONS, SO AS TO RENDER THEM MORE DURABLE AND
UFEFUL;" and the said Letters Patent contained a proviso that if the said
Charles Watt should not particularly describe and ascertain the nature of his
said Invention, and in what manner the same should be performed, by an
instrument in writing under his hand and seal, and cause the same to be
inrolled in the High Court of Chancery within two calendar months next and

page_text: immediately after the date of the said Letters Patent, then the said Letters
Patent, and all liberties and privileges whatsoever thereby granted, should
utterly cease, determine, and become void, as in and by the said Letters
Patent, reference being thereunto had, will more fully appear.
NOW KNOW YE, that in pursuance of the said proviso, and for the
purpose of particularly describing and ascertaining the nature of the said
Invention or Discovery, and the manner in which the same is to be performed,
the said Charles Watt, by this instrument in writing under his hand and seal,
doth declare, that the nature of the said Invention or Discovery, and the
manner in which the same is to be performed, is described and ascertained in
the following explanation thereof, that is to say :-
The quill or pen, after having been well cleaned, is to be dipt for ten minutes
into a dilute aqueous solution of the nitromuriate of gold. When well dried
the pen is to be exposed in a close vessel to the action of phosphuretted
hydrogen gas until a pellicle of revived gold appears. The pen is then to be
removed from the phosphuretted hydrogen gas, and suspended in another close
vessel over sulphurous acid until the gold is perfectly reduced. After this
revival it is to be dried and dipt in the same solution of gold for five minutes.
It is again to be dried, then revived by the sulphurous acid as above
described. The dipping into the solution of gold and reviving by the
sulphurous acid are to be repeated until a sufficiently thick coat of gold be
produced.
In witness whereof; the said Charles Watt hath hereunto set his hand
and seal; the Twenty-second day of December, in the year of our
Lord One thousand eight hundred and eighteen.
CHARLES WATT. (L.S.)
AND BE IT REMEMBERED, that on the same Twenty-second day of
December, in the year above mentioned, the aforesaid Charles Watt came
before our Lord the King in His Chancery, and acknowledged the Specifica-
tion oforesaid and all and Over thing therein contained in form above.
