page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EVERHARD Baron Van DOORNIK, of Well Street, in the County. of Middlesex,
send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His.
Letters Patent, under the Great Seal of the United Kingdom of Great Britain'
and Ireland, bearing date at Westminster, the Nineteenth day of December,.
in the forty-fifth year of His reign, did give and grant unto me, the said
William Everhard Baron Van Doornik, my executors, administrators," and
assigns, His especial licence, full power, sole priviledge and authority, that I,
the said William Everhard Baron Van Doornik, my.executors, administrators,
and assigns, during the term of fourteen years therein mentioned, should and
lawfully might make, exercise, and vend, within that part of His said Majesty's
Kingdom of Great Britain and Ireland called England, His Dominion of
Wales, and Town of Berwick-upon-Tweed, my Invention of "CERTAIN COMPO-
SITIONS, FORMED BY UNITING, AN ABSORBENT OR DETERGENT EARTH WITH OTHER, IN-
GREDIENTS, SO AS TO RENDER THE SAME MORE EFFECTUAL IN WASHING OR SCOURING,
AND FOR VARIOUS PURPOSES TO WHICH SOAPS OR DETERGENT EARTHS ARE NOW
APPLIED;" in which said Letters Patent there is contained a proviso, obliging
me, the said William Everhard Baron Van Doornik, particularly to 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*
to cause the same to be inrolled in His Majesty's High Court of Chancery'
within four calendar months next and immediately after the date of the said

page_text: recited Letters Patent, as in and by the same, relation being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that I, the said William Everhard Baron Van Doornik,
in compliance with the said proviso, do hereby describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,
vizj
Procure a sufficient quantity of marl or saponaceous earth, which must be
taken as clear as possible out of the ground, and put into a kiln to dry, and
when it is perfectly dry reduce it to a fine powder by grinding, sifting, or
otherwise, and then, if thought needful, expose the same to the air, either
made into cakes or otherwise, in order that its colour may be improved and
its other qualities more or less altered. To make a ton or twenty hundred-
weight of the Patent composition or soap, for general use, take six hundred
and ninety pounds weight, more or less, of tallow or other fat or oil, and
proceed by the ordinary process to convert it into soap, but when the tallow,
fat, or oil is nearly converted into soap, put into another boiler four hundred
and ten pounds weight or thereabouts of the marl or saponaceous cartli,
pulverised, sifted, and bleached by exposure to the air, if such bleaching should
be thought necessary, as before mentioned, with an equal quantity of strong.
lecs or solution of caustic alkali, stirring it constantly, and after boiling it
three, four, or five hours, as may be found necessary, pour it, when hot and in a
gluey state, into the boiler of soap, prepared with tallow, fat, oil as afore-
said, being also hot, and bring the whole again into a gluey or liquid state by
pouring into it about two hundred and ninety pounds weight of the lees, or
such quantity as may be thought sufficient, then keep it turning and boiling:
gently for about an hour, when it is to be poured into the frames, when it is
left to cool till the next day, and then cut it up with brass wires in the same:
manner as is done in the process of making soap. To make a ton or twenty.
hundredweight of the Patent composition or soap for the use of the navy, in
washing by sea water, take four hundred and thirty pounds weight, more or
less, of tallow, or other fat or oil, and proceed to convert it into soap by the
ordinary process, and when the tallow, fat, or oil is nearly converted into soap,
put into another boiler six hundred and thirty pounds weight (more or less)
of the marl or saponaceous earth, sifted, pulverized, and, if needful, bleached,
as above mentioned, with an equal quantity of lees, stirring it constantly, and
after boiling it three, four, or five hours, as may be found necessary, pour it,
when hot and in a gluey state, into the boiler of soap, prepared with tallow,
fat, or oil, as aforesaid, also hot, and bring the same again into a gluey or
liquid state by pouring it into about two hundred and ninety pounds weight of

and boiling gently for about an hour, when it is to be poured into the frames,
where it is left to cool till the next day, and then cut it up with brass wires, in
the same manner as is done in the process of making soap.

have hereunto set my hand and seal the Eighteenth day of April, in
the year of our Lord One thousand eight hundred and five.
