page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SEDGWICKB, late of Saint James's Clerkenwell, London, but now of the Town
and County of Newcastle-upon-Tyne, Surgeon, send greeting.
WHEREAS I lately petitioned His present Majestie King George the
Second, and thereby represented that I had, by long study, great application,
and at a considerable expence, invented, compleated,fand brought to perfection,
"THE ART, MYSTERY, OR METHOD OF MAKING A DRUGG CALLED SAL AMMONIACK, OR
ARMONIACK, OF GREATER PURITY THAN ANY HITHERTO IMPORTED FROM FOREIGN
PARTS;" And whereas His said present Majestie, by His Letters Patent under
the Great Seal of Great Britain, bearing date at Westminster, the Twenty-
third day of February last past, in the twenty-second year of His reign, hath,
of His especial grace, certain knowledge, and meer motion, given and granted,
and did thereby, for Himself, His heirs and successors, give and grant unto
me, the said William Sedgewicke, my executors, admors, and assigns, His
special lycence, full power, sole priviledge and authority, that I, my exe-
cutors, admors, and assigns, and every of them, by myself and themselves, or
by my and their deputy or deputys, servants or agents, or such others as I,
my executors, admors, or 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 the Kingdom of Great Britain called
England, the Dominion of Wales, and Town of Berwick-upon-Tweed, in such.
manner as to me, my executors, admors, and assigns, or any of them, shoud, in
their discretion, seem meet, and that I, the said William Sedgewicke, my
executors, admors, and assigns, shoud and lawfully might have and enjoy the
whole profit, benefit, commodity, and advantage from time to time coming,
growing, accrewing, and arising by reason of tho said Invention, for and during

page_text: the term of years therein mentioned, to have, hold, exercise, and enjoy the
said lycence, powers, priviledges, and advantages therein-before granted or
mentioned to be granted unto me, the said William Sedgewicke, my exe-
cutors, adiñiors, and assigns, for and during and unto the full end and term
of fourteen years from the dato of the said Letters Pattent next and imme-
diately ensuing, and fully to be compleat and ended, according to the Statute
in such case made and provided; in which said Letters Pattents there is a
provisoe contained to this or the like effect, that if I, the said William Sedge-
wicke, shoud 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 scal, and cause the same to be inrolled in His
Majestie's High Court of Chancery within three kallendar months next and
immediately after the date of the said Letters Patent, that then the said
Letters Pattent, and all libertys and advantages whatsoever thereby granted,
should utterly cease, determine, and become void, anything therein-before con-
tained to the contrary thereof in anywise notwithstanding, as in and by the
said Letters Pattent, reference being thereunto had, may more fully and at
large appear.
NOW KNOW YEE, that I, the said William Sedgewicke, in pursuance of
the said provisoe in the said Letters Pattent contained, and in order to make
the same valid and effectual for and during the said term, do, by this present
Instrument in writing under my hand and seal, particularly describe and ascer-
tain the nature of my said Invention, and in what manner the same is to be
performed, which is in manner and form following (that is to say):-
=
Take bones, horns, blood, or any animal substance, put them into a large
iron pott with an iron head, and an earthen or glass receiver; make a fire
under them gradually, which keep increasing for ten, twelve, or four-and-
twenty hours, in proportion to the largeness of the pott made use of and the
quantity of the matterials put in after they are cool. Take the salt, spirit, and
oyl, put them into a vessell, and let them stand twelve hours to seperate in s
the same manner as in the making volatile salt of hartshorn. When it has
stood so long, seperate the salt and spirit from the oil, which will swim on tho
top, and keep the salt and spirit for further rectification. Tako of this salt and
spirit, rectifie it twice after this manner; put them both together into a large-
bodyed retort, to which lute on a glass receiver; distill them in sand till the a
salt and spirit is raised into the receiver, which will be in twelve hours with
a moderate fire; this repeat twice, that the salt may be pure and seperated
from the flegm and oil; then take of this salt any quantity, put to it at
several times of spirit of sea salt (made after the following manner, as much
as is sufficient, that is, in chemical terms, ad punctu saturationis, or, in other 4

page_text: words, till there ceases to be any fermentation or ebullition; when that is
performed, strain the liquor thro' filtrating paper to procure a greater degree
of cleaness and purity than otherwise woud be; which done, put the liquor in
glass or well-glased earthen vessells, which put into a sand-heat, and evaporato
with a gentle fire, to perfect dryness, which will produce cakes of true sal
ammoniac, cleaner and of greater purity than the foreign; when cold, take
them out of the vessells. Take of common sea salt one pound and an half;
let it be thoroughly dryed, and ground very fine; then add to it four pounds
and a half of well-dryed and powdered tobacco-pipe clay or fullers earth, or,
indeed, any clay; mix these well together, then put them, so mixed, into an
earthen long-neck; place in it a reverberatory furnace; which done, lute on
a capacious receiver; then make a fire under it; let it be increased gradually
for ten hours that the long-neck may then be of a moderate red heat; con-
tinue this heat for five hours longer, by which time your opperation will be
finished. Let your fire goe out, and your vessells cool; then take off your
receiver, where you will find your spirit of sea salt made use of in the making
of the sal ammoniack before described.
And I do direct and order this present Instrument to be forthwith inrolled
in His Majestie's High Court of Chancery.
In witness whereof, I have hereunto set my hand and seal, the Third
day of May, in the twenty-second year of His Majestie's reign, and
in the year of our Lord One thousand seven hundred and forty-nine.
Sealed and delivered in the presence of
SED
KE.
