page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JOHNSON, of Berners Street, in the Parish of Saint Mary le Bone, otherwise
Mary Bone, in the County of Middlesex, Architect, send greeting.
WHEREAS I, the said John Johnson, did, by my humble Petition, repre-
sent to His present most Excellent Majesty King George the Third, that, by
study, application, and expence in trying experiments, found and invented "A
CHEAP, AND DURABLE COMPOSITION FOR THE COVERING THE FRONTS AND TOPS AND
ORNAMENTING OF HOUSES AND BUILDINGS, AND FOR OTHER PURPOSES IN THE BUILDING
TRADE, AND WHICH WILL ADHERE TO SURFACES THAT ARE WET AS WELL AS THOSE
THAT ARE DRY, AT ANY SEASON OF THE YEAR;" and that in regard I was the first
Inventor thereof, I therefore most humbly prayed His Majesty that He would
be graciously pleased to grant unto me, my executors, admiors, and assigns,
His Royal Letters Patent, for the sole use and exercise of his said Invention
within that part of His said Majesty's Kingdom of Great Britain called
England, His Dominion of Wales, and. Town of Berwick-upon-Tweed, for
the term of fourteen years, according to the Statute in that case made and
provided; His said Majesty, being willing to give encouragement to all arts
and inventions which might be for the publick good, was graciously pleased
to condescend to my request, and therefore, by His Royal Letters Patent,
bearing date at Westminster, the Twenty-ninth day of March, in the seven-
teenth year of His reign, of His especial grace, certain knowledge, and meer
motion, for Himself, His heirs and successors, did give and grant unto me,
the said John Johnson, my executors, adñiors, and assigns, His especial
licence, full power, sole privilege and authority, that I, the said John John-
son, my executors, adûiors, and assigns, and every of them, by myself and

page_text: themselves, and by my or their deputy or deputies, servants or agents, or such
others as I, the said John Johnson, my executors, admors, and 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 said Invention within that part of
His said Majesty's Kingdom of Great Britain called England, His Dominion
of Wales, and Town of Berwick-upon-Tweed, in such manner as to me, the
said John Johnson, my executors, admors, and assigns, or any of us, should
in our discretions seem meet, and that I, the said John Johnson, my exors,
admors, and assigns, should and lawfully might have and enjoy the whole
profit, benefit, commodity, and advantage from time to time coming, growing,
accruing, and arising by reason of the said Invention, 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 mentioned to
be granted unto me, the said John Johnson, my exors, adiñors, and assigns,
for and during and unto the full end and term of fourteen years from the
date of the said Letters Patent next and immediately ensuing, and fully to
be compleat and ended, according to the Statute in such case made and pro-
vided; in which said Letters Patent is contained a proviso that if I, the said
John Johnson, 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 said Majesty's High Court of Chancery within four 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 utterly cease, determine, and become void, anything
therein-before contained to the contrary thereof in anywise notwithstanding,
as in and by the said Letters Patent, relation being thereunto had, may more
fully and at large appear.
NOW KNOW YE, that I, the said John Johnson, in compliance with the
said proviso, do hereby describe and ascertain the nature of my said Inven-
tion, and declare that the same is composed of the several particulars, and
used in the manner following (that is to say) :-
Take any quantity of the serum of blood, to which add an equal quantity
of linseed oil; mix this liquid with a quantity of dry large-grained river sand
or other sand cleared from its loomy particles, and slaked lime or whiting
sufficient to make the composition or cement of the consistence of stiff mortar,
which is to be well beat with an instrument that is commonly used for stucco.
Let there be two thirds of sand to one third of lime. It may be used with

page_text: the tools commonly used by bricklayers and plaisterers. If it is required to
cover the fronts of buildings, &c., let the surface be first well moistened with
the liquid above described, and, after the first coat is laid on, let it be pierced
with an instrument with iron teeth of the form described in the margin, which
will prevent the composition from blistering. If the colour is to be attended
to, then for the outer coat, take the materials as above described, with the
whitest sand, to which add a proper quantity of painters' colours to make it
of such colour as may be required, subtracting from the liquid a quantity in
measure equal to the colour added.
In witness whereof, I, the said John Johnson, have hereunto set my
hand and seal, this Twenty-fifth day of July, in the year of our Lord
One thousand seven hundred and seventy-seven, and in the seventeenth
year of the reign of our said Sovereign Lord George the Third, by
the grace of God of Great Britain, France, and Ireland King,
Defender of the Faith, and so forth.
