page_text: THESE PRESENTS SHALL COME, I, SAMUEL
BROWN OLIVER, of Deptford; in the County of Kent, send greeting.
WHEREAS Her mest Execllent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Tenth day of November, One thousand eight hundred and forty-nine, in
the thirteenth year of Her reign, did give and grant unto me, the said Samuel
Brown Oliver, my exors, adiiors, and assigns, Her special license, full power,
sole privilege and authority, that I, the said Samuel Brown Oliver, my exors,
admors, and assigns, and such others as I, the said Samuel Brown Oliver, my
exors, adñiors, and assigns, should at any time agree with, and no others,
from time to time and at all times hereafter during the term of years therein
mentioned, should and lawfully might make, use, exercise, and vend, within
that part of the United Kingdom of Great Britain and Ireland called England,
the Dominion of Wales, and the Town of Berwick-upon Tweed, and in the
Islands of Jersey, Guernsey, Alderney, Sark, and Man, and in all Her
Majesty's Colonies and Plantations abroad, an Invention of "CERTAIN IM-
PROVEMENTS IN DYEING, AND DYEING MATERIALS," which said Invention was
communicated to me by Theodore Meysenburg, a foreigner residing abroad;
in which said Letters Patent there is contained a proviso, that if I, the said
Samuel Brown Oliver, shall not particularly describo and ascertain the nature
of the 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

page_text: inrolled in Iler said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, that then the said Letters Patent, and all the privileges and advan-
tages whatsoever thereby granted should utterly cease, determine, and become
void, anything therein-before contained to the contrary thereof in anywise
notwithstanding, as by the said Letters Patent, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Brown Oliver, do hereby declare that the nature of the said Inven-
tion, and in what manner the same is to be performed, are particularly
described and ascertained in and by the following statement (that is to say):-
The Invention consists in the manufacture and use of certain mixtures to
be employed in dyeing woollen fabrics, or fabrics containing a mixture of
wool.
The materials employed in the manufacture of these mixtures consist of
the following acids :-Sulphuric, nitric, arsenious, boracic, acetic, pyroligneous,
oxalic, and tartaric acids; and of the following salts,-chloride of sodium, or
common salt, salammoniac, chloride of magnesium, chloride of potassium,
sulphate of potash, sulphate of soda, sulphate of magnesia, oxalate. of potash,
acetate of potash, acetate of soda, nitrate of soda, nitrate of potash, sulphate
of zinc, and borax.
I now proceed to describe the mixtures which I prefer, but at the same
time I do not confine myself to the exact proportions which I give, because
variations in the proportions or substitution of certain of- the- materials
enumerated may be made so as
mixtures are intended.

The two mixtures above mentioned, namely, No. 1 and No. 2; are not to
be employed in grain colors, or in any other colors in which solutions of tin.

woollen fabrics, or fabrics in which a mixture of wool is present. The mixtures
before described are to be used in dyeing in the same manner as cream of
tartar or argol is now used, the same weight of the respective mixtures being
taken as would have been taken of cream of tartar or argol. The mixtures
are to be used along with the allumincus or other mordants in the ordinary
operations of dyeing. For the dyeing of dark colors, the mixtures may be
employed without the addition of other mordants, but for ordinary purposes I
employ them as a substitute for cream of tartar, or argol.
Having now described the nature of the said Invention, and the manner in
which the same is to be performed, and having stated what I consider to
be the best mixtures to be used for the purposes I have mentioned, I wish
it to be understood that I do not claim the use of the acids or salts above
enumerated when taken separately; but I do claim, as the improvements
in dyeing, and dyeing materials, communicated to me as aforesaid, the use of
such acids and salts when combined in the manner and for the purposes above
described, or when any of them are made to substitute one another in such
mixtures for like purposes.
In witness whereof, I, the said Samuel Brown Oliver, have hereunto set
my hand and seal, this Tenth day of May, One thousand eight hundred
