page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PARRISH, of Road, in the County of Somerset, Dyer, send greeting.
WHEREAS His most Excellent Majesty King George the Third' did,' by His
'Letters Patent, under the Great Seal of Great Britain, bearing date at West-
minster, the Thirty-first day of October last,' in the thirty-eighth year of His
reign, give and grant unto me, the said John Parrish, therein called John
Parrish, of the County of Somerset, His espécial licence, that'I, the said John
Parrish, my executors, administrators, and assigns, or such others as I, the
said John Parrish, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times during the
term of years therein expressed, should and lawfully might make, use, exer-
cise, and vend, within England; Wales, and the Town of Berwick-upon-Tweed,
my Invention of "A CERTAIN ART OR METHOD OF RENDERING. ALL KINDS OF
WOOLLEN CLOTH; STUFFS, HATS, AND OTHER ARTICLES, IMPERMEABLE TO MOISTURE OR
WET, OR WATERPROOP, SO AS TO RENDER EVEN THE FINEST SORTS IN A' CONDITION TO
RESIST RAIN IN EVERY SITUATION AND FOR ANY LENGTH OF TIME, WITHOUT IN THE
LEAST DEGREE AFFECTING THEIR BEAUTY, COLOUR, OR WEAR; which said Inven-
tion and improvement is altogether different from other attempts of a similar
nature which have failed by using soluble salts, or oily, gummy, and consistent
matters; the present Invention depending upon a principle which repels
humidity, and occasions rain or water to run off the surface; in the same
manner as from the feathers of water fowl and the hair of amphibious animals;
in which said Letters Patent there is contained a proviso, obliging me, the said

page_text: John Parrish, by an instrument in writing under my hand and seal, par-
ticularly 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 Majesty's High Court of Chancery within one .calendar month next and
immediately after the date of the said recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.
NOW KNOW. YE, that in compliance with the said proviso, I, the said
John Parrish, do hereby describe and ascertain the nature of my said In-
vention, and in what manner the same is to be performed, as follows, that
is to say:
I combine aluminous earth with the metalic parts of a supersaturated solu-
tion of tin and the colouring atoms of the reseda major, applying such a portion
of this combination as the substance of the cloth requires, in water, about six
degrees below a boiling heat, in which the cloth must be immersed half an
hour, when the combined resisting principles become so firmly attached to the
animal oil of the wool as to occasion the cloth to resist rain and be fully water-
proof as long as it remains whole.
In witness whereof, I, the said John Parrish, have hereunto set my hand
and seal, the Eleventh day of November, in the thirty-eighth 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,
and so forth, and in the year of our Lord One thousand seven hundred
and ninety-seven
Inrolled the Fourteenth day of November, in the year above written.
