page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EUGENE EDWARD CONWELL, of Madras, in the East Indies, but now residing at
Ratcliffe Highway, in the Parish of Saint George in the East, in County of
Middlesex, Surgeon, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of that part of the United Kingdom
of Great Britain and Ireland called England, bearing date at Westminster, the
Twenty-first day of March, One thousand eight hundred and twenty-two, in
the third year of His reign, give and grant unto me, the said William Eugene
Edward Conwell, my exors, admors, and assigns, His espécial licence, full power,
sole privilege and authority, that I, the said William Eugene Edward Conwell,
my exors, admors, and assigns, during the. term of years therein mentioned,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, and also all His Majesty's Colonies
and Plantations abroad, my Invention of "AN IMPROVEMENT IN THE PREPARATION
AND APPLICATION OF A CERTAIN PURGATIVE VEGETABLE OIL;" in which said Letters
Patent there is contained a proviso, that if I, the said William Eugene
Edward Conwell, shall 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 seal, and cause the same to be
inrolled in His Majesty's High Court of Chancery, within six calendar months
next and immediately after the date of the said Letters Patent, that then the

page_text: said Letters Patent, and all liberties and advantages whatsoever thereby
granted, shall utterly cease, determine, and become void, as in and by the same
(relation being thereunto had) will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Eugene Edward Conwell, do hereby declare that the nature of my
said Invention, and the manner in which the same is to be performed, are
particularly described -and ascertained in the following description thereof,
(that is to say) :-
I wash the croton tiglium nuts carefully, rejecting the bad or decayed; I
then boil them in clear water and carefully denude the kernels of their
envelopes, continuing to reject the bad, and wash them in lime water. I
bruise or grind the kernels and enclose them in a hair cloth, or other substance
of an open texture, which I place in a clean vessel and put it in a hot bath,
and when thoroughly heated I place the envelope containing the croton seeds
in a press and express the oil, which I filter through bibulous paper and
preserve in bottles for use. The oil may be prepared by other processes; but
my claim rests in having directed the application of it to internal use.
In witness whereof, I, the said William Eugene Edward Conwell, have
hereunto set my hand and seal, this Fifteenth day of July, in the year
of our Lord One thousand eight hundred and twenty-two.
WILLIAM EUGENE (L.S.) EDWARD CONWELL.
AND BE IT REMEMBERED, that on the Fifteenth day of July, in the
year of our Lord 1822, the aforesaid William Eugene Edward Conwell came
before our said Lord the King in His Chancery, and acknowledged the
Specification aforesaid, and all and every thing therein contained and specified,
in form above written. And. also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
Inrolled the Twenty-fourth day of July, in the year of our Lord One
thousand eight hundred and twenty-two.
