WHEREAS His most Excellent Majesty King George the Third, by His
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirtieth day of April, in the twelfth year of His reign,,
did give and grant unto me, the said Christian Wilhem Baron Van Haake
my executors, administrators, and assigns, His said Majesty's especial licence,
full power, sole priviledge and authority, that I; the said Christian Wilhem
Baron Van Haake, my executors, administrators, and assigns, and every of
them, by myself and themselves, or by mine and their deputy or deputies,
servants or agents, or such others as I, the said Christian Wilhem Baron
Van Haake, my executors, administrators, 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 "NEW-INVENTED SECRET ART OR MYSTERY IN
EXTRACTING AND MAKING FROM A CERTAIN MINERAL SEVERAL COMPOSITIONS CALLED
MINERAL TAR AND MINERAL OIL, WHICH I SUBSTITUTE INSTEAD OF TAR OR. LIQUID
PITCH INTENDED AND USED FOR THE BOTTOMS AND OTHER PARTS OF SHIPS AND
NAVIGABLE VESSELS, ALSO VITRIOL, SALTPETRE, LAMPBLACK, AND CAPUT-MORTUUM,
OF THE SAID MINERAL," within that part of His Majesty's Kingdom of Great
Britain called England, His Dominion of Wales, and Town of Berwick-upon-
Tweed, and also in His Plantations and Colonies abroad, in such manner as
to me, the said Christian Wilhem Baron Van Haake, my executors, adıni-
nistrators, and assigns, or any of them, should in their discretions seem meet

page_text: and that I, the said Christian William Baron Van Haake, my executors, admi-
nistrators, and assigns, should and lawfully might have and enjoy the whole
benefit, profit, commodity, and advantage from time to time coming, growing,
accruing, and arising by reason of the said Inventions, for and during the
term of years therein mentioned, to have, hold, exercise, and enjoy the said
licence, powers, priviledges, and advantages therein-before granted or men-
tioned to be granted unto me, the said Christian William Baron Van Haake,
my executors, administrators, and assigns, for and during and unto the full
end and term of fourteen years from the date thereof next and immediately
ensuing, and fully to be compleat and ended according to the Statute in such
case made and provided; in which said recited Letters Patent is contained
a proviso, that if I, the said Christian Wilhem Baron Van Haake, should
not particularly describe and ascertain the nature of my said Inventions, and
in what manner the same are to be performed, by an instrument in writing
under my hand and seal, and cause the same to be inrolled in His said
Majesty's High Court of Chancery within four kalendar months next after
the date thereof, then the said recited Letters Patent, and all liberties and
advantages whatsoever thereby granted, should utterly cease, determine, and
become void, anything therein-before contained to the contrary thereof in any-
wise notwithstanding, as in and by the said recited Letters Patent (relation
being thereunto had) may more fully and at large appear.
NOW, THEREFORE, KNOW YE, that I, the said Christian Wilhem Baron
Van Haake, do hereby declare my said Inventions, and declare that the same
are to be prepared in manner following (that is to say) :-
is
A number of iron cylinders being prepared, a proportional quantity of such
mineral or coal is put therein, and a large quantity of common burning coal
put round them and set on fire, which causes a fluid matter or consistence
to run or issue from the mineral or coal in the cylinder, to which I, the said
Christian Wilhem Baron Van Haake, give the name of mineral tar, from
which matter or consistence a water is drained, and a particular quantity
thereof thrown on loose ground, and let lye there until it impregnates by the
air, and when so impregnated I give it the name of vitriol. And also a par-
ticular quantity of the said water is put into a hole dug for that purpose in
the earth, and covered over so that no air can get to the same, and let lye
there till impregnated, and when so impregnated I give it the name of salt-
petre. And the residuum dregs or dross remaining after I have made use
of the said flued matter or consistence, as aforesaid, is what I then give the
name of caput-mortuum (which is the natural consequence or operation of
burning the said mineral or coal to a fluid); and that, by placing an oven or

page_text: receptacle over the said cylinders to receive the smoke or exhalation which
ascends or issues from the fire (and would otherwise evaporate in the air), is
what I give the name of lampblack. And the said ingredients or different
species of tar, vitriol, and saltpetre (when so extracted and impregnated as
aforesaid), being all compounded, or mixed, and put together in their respective.
due or fit proportions, they alone compose that liquid composition so invented,
found out and prepared, substituted and used, by me, the said Christian
Wilhem Baron Van Haake, for preserving such ships, vessels, (and timber,)
in manner aforesaid, and by me called by the said name of mineral tar or
mineral oil.
In witness whereof, I, the said Christian Wilhem Baron Van Haake,
have hereunto set my hand and seal, this Twenty-eighth day of
August, in the twelfth year of the reign of our Sovereign Lord
George the Third, by the grace of God of Great Britain, France, and
Ireland King, Defender of the Faith, &c., and in the year of our
Lord One thousand seven hundred and seventy-two.
