CERTAIN IMPROVEMENTS IN A MEDICINE THEN CALLED 'CHING'S WORM DESTROYING LOZENGES'
Year: 1808

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, REBECCA
CHING, of Rush Common, in the Parish of Saint Mary, Lambeth, in the
County of Surrey, widow of John Ching, late of Cheapsido, in the City of
London, Apothecary, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventh day of May,
in the forty-eighth year of His reign, give and grant unto me, the said Rebecca
Ching, my exors, admiors, and assigns, His especial licence, full power, sole
privilege and authority; that I, the said Rebecca Ching, my exors, admors,
and assigns, during the term of fourteen years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS
IN A MEDICINE THEN CALLED 'CHING'S WORM DESTROYING LOZENGES';" for which
medicine my said late husband obtained His Majesty's Letters Patent, bearing
date on or about the Twenty-eighth day of June, One thousand seven hundred
and ninety-six, and duly inrolled a Specification of such his Invention in His
Majesty's High Court of Chancery, to which Specification I do refer, in order

page_text: the more fully to ascertain my improvements; in which said Letters Patent
there is contained a proviso, obliging me, the said Rebecca Ching, 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
prepared, to be enrolled in His Majesty's High Court of Chancery within
one calendar month after the date of the said recited Letters Patent, as in
and by the same, relation being thereunto bad, may more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Rebecca Ching, do hereby declare that my said Invention of certain improve-
ments in a medicine called "Ching's Worm Destroying Lozenges," is parti-
cularly described and ascertained in manner following, that is to say:-
Take sub murias hydrargyri, 1; saccharum album, xvlbs; crocus sativus, 3 fs,
aquæ fontana, 1b; boil the crocus in the aqua for ten minutes, then strain and
beat the whole into a mass, which mass roll out of an exact thickness, which is
of great importance in regulating the doses; it is therefore done by means of
a brass roller on a particular construction, that is to say, cach end of the roller
has an enlargement, which keeps the middle part about an eighth of an inch
from the table, and thus admits the roller to pass over the mass, forming it
of a regular and exact thickness; then cut out the lozenges with a tin-plate
instrument, similar to what is used for other lozenges, differing only in its
form, this being oval (and others round). The yellow lozenges thus made
contain exactly half a grain of sub murias hydrargyri to each lozenge.
The dose, from one lozenge to six, the last thing at night, and the like
number of the following brown lozenges the first thing in the morning:--
Take extractum convolvulus jalapii, lb. iii fs.; pulv. spigelia Marilandica.
b. vi.; sacharum album, lb. ix.; aquæ fontana, a sufficient quantity to make
a mass; which mass roll and cut out in like manner as directed for the yellow
lozenges. Both kinds must be dried by being exposed to the sun; a few
hours will prove sufficient for the yellow lozenges, but the brown lozenges
will require as many days.
In witness whereof, I, the said Rebecca Ching, have hereunto set my
hand and seal, this Twenty-fifth day of May, in the year of our Lord
One thousand eight hundred and eight.
R. CHING. (L.S.)
