page_text: CHAPPELL'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DANTELL
CHAPPELL, Citizen and Merchant Taylor of the City of London, send greeting.
WHEREAS His most Excellent Majesty King George the Second, by His
Letters Patent under the Great Seal of Great Britain, bearing date the
Seventh day of August, in the sixteenth year of His reign, did give and grant
unto me, the said Daniel Chappell, His especiall licence that I, the said
Daniel Chappell, during the term of years therein expressed, should and
lawfully might use, exercise, and vend my new Invention of "THE ART OF
PRINTING SEVERAL SORTS OR SPECIES OF WOOLLEN MANUFACTURES OF THEIR
SEVERAL KINDS, SUCH AS GOODS MADE OF ALL WOOL, GOODS MADE OF WORSTED
AND SILK, MOHAIR AND SILK, AND OF PLAIN MOHAIR, OF THEIR
KINDS," which, to the best of my knowledge, was never before practiced
or done by any person in the same manner in the Kingdom of Great
Britain or elsewhere; in which said recited Letters Patent there is contained a
provisoe obliging me, the said Daniell Chappell, by a writing under my hand
and seal, to cause a particular description of the nature of the said Invention,
and in what manner the same is to be performed, to be inrolled in His Ma-
jesty's High Court of Chancery within three kalendar months after the date
of the said recited Letters Patent, as in and by the same (relation being there-
unto had) may more at large appear.
NOW KNOW YE, that in compliance with the said provisoe, I, the said
Daniel Chappell, do hereby declare that the said Invention does consist, and
is to be performed in the manner herein-after mentioned, that is to say :-
All the aforesaid goods are to be printed with prints cut or carved in wood,
in the same manner as callicoes or linnens are printed, with a preparative

page_text: made of allom, arsnick, white Argyl chalk, and saccarum saturni, mixed alto-
gether in liquor thickened with gum arabick, which produces several different
colours when dyed. And for producing several different shades of the several
different colours, the vitriol of Mars is to be added to the materials above
mentioned, which will narigate the several colours into stronger or weaker
shades when dyed with madder or other dye stuffs used by linnen printers.
Some of the above goods I print with the aforesaid prints with colours that I
strike at once, the goods being before prepared with shewmack, without any
further dying. Some other of the said goods I print with the aforesaid prints,
and fix the colour in cold liquors of vitriol of Mars after they are printed. I
likewise print all the aforesaid goods with prints made chiefly of lead, such as
are customarily used in printing blew and white callicoes or linnens, with a
preparative made of glew or some other glutinous substance, to preserve the
white where it is wanted in the pattern, and then dye them with any colour
that is wanted, as is done in the way of printing callicoes or linnens.
In witness whereof, I, the said Daniel Chappel, have hereunto set my
hand and seal, this First day of October, One thousand seven hundred
