Year: 1811

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
RANDOM DE BERENGER, formerly of Germany, but now residing in Pall Mall,
in the City and Liberty of Westminster, in the County of Middlesex, Gentle-
man, send greeting.
WHEREAS His present Majesty King George the Third, in and by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-first day of November last, for Himself, His heirs and
successors, did give and grant unto me, the said Charles Random de Berenger,
His special licence, full power, sole privilege and authority, that I, the said
Charles Random de Berenger, my exors, admors, and assigns, and every of
them, by myself and themselves, or by my and their deputy or deputies,
servants or agents, or such others as I, the said Charles Random de Berenger,
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 ex-
pressed, should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention for "CERTAIN
MEANS OF PRODUCING A VALUABLE OIL, AND ALSO SOAP AND BARILLA, AND A BLACK
COLOUR OR PIGMENT;" in which said Letters Patent there is contained a proviso
obliging me, the said Charles Random de Berenger, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature of
my said Invention, and in what manner the same is to be performed, and to
cause the same to be enrolled in His Majesty's High Court of Chancery

page_text: within two calendar months next and immediately after the date of the said
recited Letters Patent.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Charles Random de Berenger, do hereby describe and ascertain that my
Invention consists in producing of a valuable oil, as also soap and barilla, and
a black colour or pigment, from the plants or vegetables known by the name
of euphorbias; and though the different euphorbias all, more or less, can be
made the means to produce the above, the euphorbia lathyris is preferable to
the others, being the most productive. I either cultivate the said euphorbias,
or, seeking them in their wild state of vegetation, collect the ripe seeds or
fruit, which I press (in the usual way employed to press oil from seeds), there-
from obtaining a very superior oil, useful for a variety of domestic purposes.
The pulp or dregs remaining after the oil has been pressed inay be made into
soap, by adding and mixing barilla and a little of the oil (above alluded to) to
it, which animal fat or grease at pleasure may or may not be added. The
stalk, branches, leaves, and other parts of the euphorbias burnt, produce also a
kind of barilla; and to obtain the black color or pigment, the dregs or pulp
(formed of the pressed seeds above mentioned must be burnt in a crucible,
watching it carefully to ascertain its perfection in the customary way to obtain
pigment by burning.
In witness whereof, I, the said Charles Random de Berenger, have here-
unto set my hand and seal, this Twenty-first day of January, in the
year of our Lord One thousand eight hundred and twelve.
