TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS His Majesty King George the Second, by His Letters Patent,
dated at Westminster, the First day of April, in the nineteenth year of His
reign, of His special grace, certain knowledge, and meer motion, did give
and grant, for Him, His heires & successors, unto me, DIEDERICK WESSELL
LINDEN, of Southampton Street, Covent Garden, in the County of Middx,
Doctor of Physick, my executors, administrators, & assignes, His especial
licence, full power, sole privilege & authority, that I, my executors, admors,
and assignes, & every of us, by myself & themselves, or by my & their deputy
& deputys, servants or agents, or such others as I, my exors, adm", or
assignes, should at any time agree with, and no others, from time to time
& at all times hereafter during the term of fourteen years from the date
of the said Patent, should and lawfully might, within that part of Great
Britain called England, the Dominion of Wales, & Town of Berwick-upon-
Tweed, make, use, exercise, & vend my Invention in such manner as to me,
my exec, adm", and assignes, or any of us, should seem meet; and which I,
the said Diederick Wessell Linden by and at great pains & expence have
brought to perfection, with such other powers & libertys as is and are therein
expressed; nevertheless subject to a provisoe therein contained, that if I, the
said Diederick Wessell Linden, should not particularly describe and ascertain
the nature of the said Invention, and in what manner the same is to be per-
formed, by an instrument in writing under my hand & seal, and cause the
same to be inrolled in His Majesty's High Court of Chancery within three
kalendar next & imediately after the date of said Letters Patent, that
then the same Letters Patent, & all libertys & advantages thereby granted
should utterly cease, determine, & become void, as in and by the said

page_text: Letters Patent, whereunto [relation being had, doth more fully and at large
appear.
NOW KNOW YE, that I, the said Diederick Wessell Linden, in pursu-
ance of the said provisoe, do hereby declare that I take coñion salt, or salt
water, lime, scorios of iron, or stones which have iron in them, loom, and all
sorts of green vegetables; all manner of animal productions, as urine, dung,
blood, or flesh which was killed or dyed of itself; & all this I mix, and put
into a pit for putrefaction. I am not bound to a certain quantity of the above
ingredients, so that it don't signify which is the most. After it is well putri-
fyed, which by the smell & tast is to be known, because then it smells like salt-
petre brine, then I expose it to the air, in order to dry it; when it is dry then
I lixive out the saltpetre, to which I put so much lixivium or caustick alkali
till the ebullution is over; then I put it into a boiler and boil it so long till the
liquor, when thrown into the fire, burns; then I take it out and put it into a
cool place for christalls, which christalls are saltpetre, fitt for use.
In witness whereof, I, the said Diederick Wessell Linden, have hereunto
sett my hand and seal, this Twenty-first day of June, in the twentieth
year of the reign of our Sovereign Lord George the Second, 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 forty-six.
