Year: 1822

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
FORD, of Abingdon Row, Goswell Street Road, in the County of Middlesex,
Chemist, 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-fourth day of April, 1822, in the third year of His reign, give and
grant unto me, the said Robert Ford, my exors, adiiors, and assigns, His
especial licence, full power, sole privilege and authority, that I, the said
Robert Ford, my exors, adñiors, 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, my Invention or
discovery of "A CHEMICAL LIQUID OR SOLUTION OF ANNOTTO;" in which said
Letters Patent there is contained a proviso, that if I, the said Robert Ford,
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 two calendar months next and immediately
after the date of the said Letters Patent, that then the 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Ford, 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
To make twenty gallons of the chemical liquid or solution of annotto, I take
fifty-six pounds of annotto, more or less; I reduce it with warm water, then
pass it through a fine sieve, let it stand seven days, or longer, then I add the
leys of subcarbonated potash, a sufficient quantity to produce the colour
required; the quantity, and also the strength, must depend on the colour it is
intended to produce, and also on the quality of annotto (other suitable articles
may be used for this purpose); then I add to the above about six pints of the
aqua lixivum caustic, more or less, then I take alkohol, one hundred and
ninety-two ounces, and mix the whole together, keeping it in a closed vessel.
I further declare that as my Invention consists in producing a liquid or
solution of annotto, an article I believe to be entirely new, I shall consider any
similar production, whether from different articles, or variation of quantity of
the aforesaid articles, or by what means they are produced, as an infringement
on my Patent right, as every chemist must be aware that there are ingredients
other than those mentioned above which may with effect be made to supply
their or either of their places.
In witness whereof, I, the said Robert Ford, have hereunto set my
hand and seal, this Twenty-first day of June, in the year of our Lord
One thousand eight hundred and twenty-two.
