EVERHARD BARON VON DOORNIK, of Wells Street, Wellclose Square, in the
County of Middlesex, send greeting..
WHEREAS His present most Excellent Majesty King George the Third, in
and by His Royal Letters Patent under the Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Seventh
day of February, in the forty-ninth year of: His reign, did give and grant
unto me, the said William Everhard Baron von Doornik, His especial licence,.
full power, sole privilege, and authority that I, the said William Everhard
Baron von Doornik, my executors, administrators, or assigns, or such others
as I, the said William Everhard Baron von Doornik, my executors, adminis-
trators, or assigns, should at any time agree with, and no others, from time to
-time and at all times during the term of years therein mentioned, should and
lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, and also in all His said Majesty's Colonies
and Plantations abroad, my Invention of "CERTAIN IMPROVEMENTS IN THE
MANUFACTURE OF SOAP TO WASH WITH SEA WATER, WITH HARD WATER, AND
WITH SOFT WATER;" in which, said. Letters Patent there is contained a
proviso obliging me, the said William Everhard, Baron von Doornick, 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 inrolled in His said Majesty's

page_text: High Court of Chancery within six calendar months next and immediately
after the date of the said Letters Patent, as in and by the same Letters
Patent, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Everhard Baron von Doornik, do hereby describe and ascertain the
nature of my said Invention, and the manner in which the same is to be
performed, as follows, that is to say:-
My Invention consists in intimately uniting and intermixing the gall of
animals and also lime in all states of combination with carbonic acid or the
carbonats of lime, or carbonats of lime in conjunction with the phosphat or
sulphat of lime, or both, or any of the natural substances in which lime
composes the principal part, with soap or saponaceous substances, whether
formed of oil, fat, tallow, rosin, wool, fish, flesh, or any other substance
whatever from which soaps are known to be made, or with combinations of all
or any of those substances saponized by soda, potash, or any alkali whatever.
To make soap for the purpose of washing with sea water and hard water, I
take about one hundred and twelve pounds of town tallow, or a proportionate
quantity of fat, oil, or any other substance or combination of substances from
which soaps are made, and proceed by any of the usual processes to convert
the same into soap, or nearly so; I then add about eighty pounds of fine
carbonate of lime, or any other of the calcareous substances above mentioned,
in combination with about ten gallons of weak soap lees, or with water, but I
prefer the solution of weak soap lees and carbonate of lime, which I introduce
into the soap, both being in a warm state, agitating the mass for several hours,
raising and keeping the same to the boiling point, which is generally sufficient
to convert the whole mass into soap, or that state which is technically called
finished; then I withdraw the fire, and after suffering the mass to cool to the
temperature of about one hundred and eighty degrees by Fahrenheit's scale, I
add about seven pints of the gall of animals, or that, if in a coagulated state,
diluted with a small quantity of water or weak soap lees, continuing the agita-
tion till a compleat admixture takes place, when I put it into the frames in
the usual way, and when it is sufficiently cooled I cut it up, as is usually done
by other soapmakers. By this means the soap produced will answer the purpose
of washing in sea water and in hard water, is more oeconomical, and scours and
washes better than soap made by any former process. To make soap
for washing in soft water, and all the purposes for which common soaps are
used, I proceed exactly as above described for making sea and hard water
soap. only observing the following variations in the quantities of the materials,
videlicit: To one hundred and twelve rounds of town tallow, or a propor-

page_text: tiorate quantity of any other substance or combination of substances from
which soaps are now made, add about twenty-eight pounds of fine carbonate
of lime, or any other of the calcareous substances above mentioned, in solution
with about nine gallons of weak soap lees or water and about two pints of
animal gall. To improve soft soap, and make it wash in hard water and sea
water, I take soft soaps formed of any substances of which soft soaps are gene.
rally made, or proceed in the usual way to make soft soap. To every one hundred
weight I add about fifty-six pounds of fine carbonate of lime, or any other of
the calcareous substances above mentioned, in a state of solution, with about
twelve gallons of pearl or pot ash lees, or any other soap lees of which soft soaps
are male, of a middling strength, the soap and solution to be united, both
being in a warm state, and at the same time to be well agitated and brought
to the temperature of about one hundred and eighty of Fahrenheit's scale; then
add about seven pints of animal gall, and when the same is intimately mixed
the soap is completed, and will answer all the purposes above described. To
improve soft soap for general purposes in soft water, proceed exactly as described
for improving soft soap for washing in sea water and hard water, only observe
to add about nineteen pounds of the carbonate of lime or any other of the
calcareous substances above mentioned, in solution, with about ten gallons of
pearl or pot ash lees, or any other soap lees of which soft soaps are made, of a
middling strength, and about two pints of animal gall, in lieu of the proportions
before described. Soap made in this way will wash and scour woolens,
flannels, cotton, linen, and a variety of other articles in a superior manner to
the soaps made previous to my Invention.-N.B. The proportions of the
different ingredients herein-before mentioned are those which by experience I
have found best calculated to effect my object, but I have prefixed to the
quantity of each the word "about," because though the proportions I have
stated are sufficient for the purpose, yet a trifling variation may be made in
the quantities of the different component parts of my Invention without pro-
ducing any material alteration in the soaps to be manufactured according to
my improvements.
In witness whereof, I, the said William Everhard Baron von Doornik,
have hereunto set my hand and seal, this Seventh day of August,
in the forty-ninth year of the reign of our Sovereign Lord George
the Third, by the grace of God of the United Kingdom of Great
Britain and Ireland King, Defender of the Faith, and in the year
of our Lord One thousand eight hundred and nine.
B. V. (L.8.) DOORNIK.
