page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, OBADIAH
WYLD, of London, Gentleman, sendeth greeting.
WHEREAS His present Majesty King George the Second, in and by
His Letters Patent under the Great Seal of Great Britain, bearing date the
Seventeenth day of March now last past, hath given and granted unto the said
Obadiah Wyld, his extors, admors, and assignes, especiall lycence, full power,
sole priviledge and authority of making, using, exercising, and vending a new
Invention of "MAKING OR PREPARING PAPER, LINNEN, CANVASS, AND SUCH LIKE
SUBSTANCES, WHICH WILL NEITHER FLAME NOR RETAIN FIRE, AND WHICH HATH ALSO
A PROPERTY IN IT OF RESISTING MOISTURE AND DAMPS," for and during the term
of fourteen years from the day of the date thereof; in which said Letters Patents
is contained a provisoe that if the said Obadiah Wyld should not particularly
describe the nature and form of his said Invention, by an instrument in writing
under his hand and seal, and cause the same to be inrolled in the High Court
of Chancery within two calender months next and imediately after the date of
the said Letters Patent, then those Letters Patent, and all libertys and advan-
tages whatsoever thereby granted, should utterly cease, determine, and become
void, as by the said in part recited Letters Patent, relation being thereunto
had, may more fully and at large appear.
NOW THESE PRESENTS WITNESS, that in pursuance of the aforesaid
provisoc in the said Letters Patent contained, he, the said Obadiah Wyld,
doth hereby (being within two calender months from the date of the said
Letters Patent) own, confess, declare, and acknowledge that the nature and
form of his said Invention, and the manner in which the same is used, whereby

page_text: paper, linnen, canvass, and such like substances are prevented from flaming or
retaining fire, as also from receiving any moisture or damps, is as follows (that
is to say):-
By mixing allom, borax, vitreol, or copperas dissolved and beat up with the
pulpy substance before 'tis formed into paper, and when the paper is dryed to
dip it into a thin size made warm, and the method whereby paper already
made, as also linnen, canvass, and such like substances, are prevented from
flaming or retaining fire, is by dipping them into a strong infusion of the afore-
said materialls in water or thin size mado hot; but if only water is used in the
first dipping they must when dry be dipped in a thin size; and the method
whereby paper, linnen, canvass, and such like substances, so prepared as afore-
said, are made to resist moisture and damps, is by mixing drying oyl with the size
in the last dipping, or by pressing or laying the paper, linnen, canvass, and
such like substances between other paper, paste boards, or cloths, moistned
with drying oyl, or by moistning the said paper, linnen, canvass, and such like
substances with drying oyl.
In witness whereof, the said Obadiah Wyld hath hereunto set his hand
and seal, this Fifteenth day of April, in the year of our Lord Ono
thousand seven hundred and thirty-five, and in the eighth year of reign
of our Sovereign Lord George the Second, by the Grace of God of
Great Britain, France, and Ireland King, Defender of the Faith, &c.
