page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, JOHN WHITE,
the younger, of Whitehall Wharf, in the Parish of Saint Margaret, West-
minster, Gentleman, sends greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-ninth day of
September, in the forty-ninth year of His reign, give and grant unto me, the
said John White, my exors, adñors, and assigns, His said Majesty's especial
licence, full power, sole priviledge, and authority, that I, the said John White,
my exors, admors, and assigns, and every of them, by myself, and themselves,
or by my own or their deputy or deputies, servants or agents, or such others
as I, the said John White, my exors, 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 therein expressed, should and lawfully might make,
use, exercise, and vend, my Invention or discovery of "A CERTAIN SUBSTANCE
WHICH IS CAPABLE OF BEING CONVERTED INTO STATUES, ARTIFICIAL STONE MELTING
POTS, BRICKS, TILES, SUGAR BAKERS' PANS, CHIMNEY POTS, GARDEN POTS, AND
EVERY DESCRIPTION OF POTTERY," within that part of the United Kingdom of
Great Britain and Ireland called England, the Dominion of Wales, and
Town of Berwick-upon-Tweed, to have, hold, exercise, and enjoy, the said
licence, powers, priviledges and advantages therein-before granted unto me, the
said John White, my exors, admors, and assigns, for and during, and unto the

page_text: full end and term of fourteen years from the date of the said Letters Patent
rext, and immediately ensuing, and fully to be complete and ended; in which
said Letters Patent there is contained a proviso, that if I, the said John White,
should not particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed; by an instrument in writing
under my hand and seal, and cause the same to be inrolled in His Majesty's
High Court of Chancery within two calendar months next and immediately
after the date of the said Letters Patent, that then the said Letters Patent,
and all liberties and advantages whatsoever thereby granted, should cease,
determine, and become void, as in and by the said Letters Patent, relation
being thereunto had, will more fully appear..
NOW KNOW YE, that in compliance with the said proviso, I, the said
John White, do hereby declare that the nature of my said Invention or dis-
covery, and the manner in which the same is to be performed, are particularly
described, as follows (that is to say) :-
Instead of the potters' clay or other argillacious earths which are dug out
of the ground and used and applied for manufacturing and making bricks,
tiles, and other articles of pottery, I do take from the bed or channel of the
river Thames, or from the creeks, or openings, or docks, or other cavities or
places into which the waters of the said river are suffered to enter or flow,
within or near the cities of London and Westminster, the borough of South-
wark, and parts adjacent within the flow of the tide, such portions as I may
have occasion for of the deposit, or alluvial soil, or siltage which subsides in
the said river, and the creeks, openings, docks, cavities, and places aforesaid,
and which, by various researches, experiments, and observations, I have found to
consist for the most part of argillaceous earth, clay, or chalk, and sand, from the
uplands, along with materials of the nature of pit coal, ashes, sand, and with the
remains of the organized matters from these extensive towns, and which is the
substance first herein-before mentioned, and I do select in preference such
parts, samples, or masses of the said deposit, or alluvial soil, or siltage as
upon examination, I find to be most clear of worms and aquatic animals, and
most plastic and fit for the purpose of making statutes, artificial stone melting
pots, bricks, tiles, sugar bakers' pans, chimney pots, and garden pots, and
other articles of pottery, as aforesaid; and I do, according to the intention
or purpose to which the said deposit, or alluvial soil, or siltage is or may be
required to be applied, modify, alter, and improve the same by the addition
of such proportions of natural clay and sand, or either of them, as may be
needful, and as may easily be ascertained by any competent workman by
such trials as in all such cases are needful to be made in the art of pottery

page_text: and brick-making, and I do place and dispose the said parts, samples, or
masses when so selected or taken upon a sloping bank or support, in order
that the water may drain therefrom, and I do use and apply the same, with
or without the modification and improvements aforesaid, for manufacturing
and making statues, artificial stone melting pots, bricks, tiles, sugar bakers*
pans, chimney pots, garden pots, and every description of pottery, by the
methods, and with or without the glazing and colouring materials, and with the
use of such implements, tools, furnaces, and structures as are commonly and
respectively practised, used, an employed, according to the nature of the
several exigencies requiring or demanding the same.
In witness, whereof, I, the said John White, have hereunto set my hand
and seal, the Twenty-seventh day of November, in the year of our Lord
One thousand eight hundred and nine
AND BE IT REMEMBERED, that on the Twenty-seventh day of November,
in the year of our Lord 1809, the aforesaid John White, the younger, came
before our said Lord the King in His Chancery, and acknowleged the Speci-
fication aforesaid, and all and every thing therein contained and specified, in
form above written. And also the Specification aforesaid was stampt according
to the tenor of the Statute made for that purpose.
Inrolled the Twenty-seventh day of November, in the year of our Lord
One thousand eight hundred and nine.
