page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BARTON, late of Old Street, in the Parish of. Saint Luke, in the County of
Middlesex, Chymist, but now of Berners Street, in the Parish of Saint Mary-
le-bone, in the said County of Middlesex, Doctor of Physic, 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
Westminster, the Twenty-eighth day of January, in the thirty-eighth year
of His reign, give and grant unto me, the said Joseph Barton, His especial
licence that I, the said Joseph Barton, during the term of years therein
mentioned, should and lawfully might use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my discovery of "A MEDICINE
OR CHEMICAL PREPARATION WHICH I DENOMINATE COMPOUND CONCENTRATED FLUID
VITAL AIR, OF GREAT USE IN THE CURE OF ALL PUTRID DISEASES, FEVEROUS,
SCROPULOUS OR SCORBUTIC, AS WELL AS ASTHMATIC, PARALITIC AND NERVOUS COM-
PLAINTS; AND, FOUNDED ON THE SAME BASIS OF DISCOVERY, ANOTHER PREPARATION,
WHICH I CALL AERIATED PREVENTATIVE FLUID, AS A PREVENTATIVE FROM PUTRID,
MORBID, OR VIRULOUS INFECTION; AND ALSO, FOUNDED ON THE LIKE BASIS OF
DISCOVERY, AERIATED LIQUID BALM FOR THE PRESERVING AND BEAUTIFYING THE
SKIN;" in which said Letters Patent there is contained a proviso obliging me,
the said Joseph Barton, by an instrument in writing under my hand and
seal, to cause a particular description of the nature of my said Invention, and
in what manner the same is to be performed, to be inrolled in His Majesty's
High Court of Chancery within one calendar month after the date of the said

page_text: recited Letters Patent, as in and by the same (relation being thereunto had,
may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Barton, do hereby declare that my said discovery is described in
manner following (that is to say):-
Vital air oxigin, or depholgesticated air, may be obtained from various
substances, viz, almost all metallic substances and metallic calxis from clays,
earths, &c. The sole agency of heat is sometimes sufficient to disengage vital air
from the substance containing it, but generally vegetable or mineral acids are
necessary to the production of a quantity sufficient for real medical use. The
mode which I pursue is, first to ascertain the quantity of vital air any substances
1 mean to obtain it from contains, and then to put into a retort a quantity of
the analyzed material with or without any decomposing acid, as may be
necessary. To this retort is then attached a tubulated receiver in part filled
with water, through which the vital air is made to pass; the mephitic air or
cretaceous acid, which almost always will rise with the vital air, will attach
itself to the water. A second receiver adapted to the first, into which pure
spirit or alcohol is gradually introduced, will then receive the vital air free
from the mephetic gas: the pure vital air combining with the spirit forms the
liquid of compound concentrated fluid vital air; but as inflammable air will
often be produced in the operation, a third receiver attached to the second, as
the second to the first, will be found necessary or at least highly useful, into
which the inflammable air will, from its lightness, readily ascend, and may be
got quit of by absorption, in an alkaline solution in the third receiver, or by
occasionally opening the stopper of the third receiver. Vital air, simply combined
with pure spirit in the mode before mentioned, is perhaps the most universal
solvent in existence, and in peculiar cases may be combined with all or any of
the curative medicines with singular advantage; but in the diseases mentioned in
my Patent, singly and alone it is a curative. Aeriated preventive fluid is made in
the same manner as to apparatus, but instead of spirit in the second receiver
the vital air is combined with essential oil and distilled water. Aeriated liquid
balm is also made by the same process, only into the second receiver a sufficient
quantity of the flowers of roses, jassamine, &c., or of the expressed as well as
essential oils of sweet-smelling vegetables is introduced to enable the distilled
water to combine with and retain the vital air.
In witness whereof, I, the said Joseph Barton, have hereunto set my
hand and seal, this Twenty-eighth day of February, in the year of our
Lord One thousand seven hundred and ninety-nine.
JOSEPH BARTON. (L.S.).
