page_text: COOPER'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
COOPER, of Haverton, in the County of Wilts, Clothier, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-first day of April, in the first year of Her reign, and
in the year of our Lord One thousand eight hundred and thirty-eight, did, for
Herself, Her heirs and successors, give and grant unto me, the said Edward
Cooper, Her especial license, sole privilege and authority, that I, the said
Edward Cooper, my executors, administrators, and assigns, and such others
as I, the said Edward Cooper, my executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times 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, my Invention of "AN IMPROVEMENT IN THE MAKING OR
MANUFACTURING OF SOAP;" in which said Letters Patent is contained a pro-
viso obliging me, the said Edward Cooper, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature of
my said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in Her Majesty's High Court of
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as in and by the same; reference being
thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Cooper, 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 and by the following description thereof (that
is to say):-
My improvement in the manufacturing of soap consists in the employment
of an oleaginous substance extracted from the seeds of the sesamum plant, a
native of East India, which is imported into this country in large quantities in
the form of oil, and also in the seeds, which by compression yield the oil
in very considerable abundance. This oil I use in the same way as olive oil or
other oleaginous or fatty matters by mixing it with alkaline materials in the
way that soap is usually made. The quantity of alkaline materials to be
employed with any given quantity of the oil must depend upon the strength
and goodness of the oil, which practical experience in the art of soap making
alone can determine. The soap so produced is much superior in its working
properties to other soaps, and can be made at a considerably reduced cost.
The subject, therefore, of my Invention, and that of which I claim the
'exclusive use under the above in part recited Letters Patent, is, the employment
of the oil obtained from the sesamum plant for the making or manufacturing of
soap.
In witness whereof, I, the said Edward Cooper, have hereunto set my
hand and seal, this Nineteenth day of October, in the year of our
Lord One thousand eight hundred and thirty-eight.
EDWARD (L.s.) COOPER,
AND BE IT REMEMBERED, that on the Nineteenth day of October,
in the second year of the reign of Her Majesty Queen Victoria, the said
Edward Cooper came before our said Lady the Queen in Her Chancery,

said was stamped according to the tenor of the Statute made in the
fifty-fifth year of the reign of His late Majesty King George the Third.
Inrolled the Twentieth day of October, One thousand eight hundred
and thirty-eight.
