the County of Middlesex, Esquire, and George Fergusson
Wilson, of Belmont, Vauxhall, in the County of Surrey, Ma-
naging Director of Price's Patent Candle Company, for the
PROVISIONAL SPECIFICATION left by the said George Gwynne
and George Fergusson Wilson at the Office of the Commis-
sioners of Patents, with their Petition, on the 23rd December
1852.
We, GEORGE GWYNNE, of Hyde Park Square, in the County of
Middlesex, Esquire, and GEORGE FERGUSSON WILSON, of Belmont,
Vauxhall, in the County of Surrey, Managing Director of Price's
Patent Candle Company, do hereby declare the nature of the said

page_text: Invention for "IMPROVEMENTS IN TREATING FATTY AND OILY MATTERS "
to be as follows:-
This Invention consists of removing an injurious consequence of
the treatment of greasy matters with powerful acids, which appear
either actually to combine with the oily and fatty matters, or, at
any rate, to mix mechanically so closely as to be difficult to sepa-
rate. We have found that salts of powerful acids, particularly
sulphuric acid, such as sulphate of ammonia, will effect this sepa-
ration.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said George Gwynne and George Fergusson
Wilson in the Great Seal Patent Office on the 23rd June 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
GEORGE GWYNNE, of Hyde Park Square, in the County of Middle-
sex, Esquire, and GEORGE FERGUSSON WILSON, of Belmont, Vaux-
hall, in the County of Surrey, Managing Director of Price's Patent
Candle Company, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

unto us, the said George Gwynne and George Fergusson Wilson,
Her special licence that we, the said George Gwynne and George
Fergusson Wilson, our executors, administrators, and assigns, or
such others as we, the said George Gwynne and George Fergusson
Wilson, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man,

page_text: an Invention for "IMPROVEMENTS IN TREATING FATTY AND OILY MATTERS,"
upon the condition (amongst others) that we, the said George
Gwynne and George-Fergusson Wilson, or one of us, by an instru-
ment in writing under our hands and seals, or under the hand and
scal of one of us, should particularly describe. and ascertain the
nature of the said Invention, and in what manner. the same was
to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.."
NOW KNOW YE, that I, the said George Fergusson Wilson, on
behalf of myself and the said George Gwynne, do hereby declare
that the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof (that is to say):
This Invention consists of removing an injurious consequence
of the treatment of greasy matters with powerful acids, which
appear either actually to combine with the oily and fatty matters,
or, at any rate, to mix mechanically so closely as to be difficult
to separate. We have found that salts of powerful acids, particu-
larly sulphuric acid, such as sulphate of aminonia, will effect this
separation.
This Invention, therefore, consists of employing such salts, after
powerful acids have been used, in treating fatty and oily matters.
And in order that our said Invention may be most fully under-
stood, and readily carried into effect, we will proceed to describe the
means pursued by us.
We have found that fatty and oily matters that have been
treated with powerful acids, especially with sulphuric acid, are
injured in their burning qualities, and that by subjecting the
acidified natter to a treatment with salts of powerful acids, we
obtain very beneficial results. For this purpose we prefer to
employ sulphate of ammonia, though other salts of strong acid may
be used. After acidification is complete, we add ten pounds of
sulphate of ammonia to the one hundred and twelve pounds of

page_text: acidified matter, and boil up for an hour by free steam; the acidified
material is then removed, and is ready to be made into candles.
In witness whereof, I, the said George Fergusson Wilson, have
hereunto set my hand and seal, this Twentieth day of June,
in the year of our Lord One thousand eight hundred and
fifty-three
