page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
SERAPHIN FAUCON, of Rouen, in the Kingdom of France, Banker, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourteenth day of
January, One thousand eight hundred and forty-seven, in the tenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Seraphin Fauçon, my exors, adñors, and assigns, Her
especial licence, full power, sole privilege and authority, that I, the said
Joseph Seraphin Fauçon, my exors, adñiors, and assigns, or such others as I,
the said Joseph Seraphin Fauçon, my exors, adñiors, 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 expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "IMPROVEMENTS IN THE MANUFACTURE OF SOAP;" in
which said Letters Patent is contained a proviso that I, the said Joseph
Seraphin Fauçon, shall cause a particular description of the nature of my

page_text: said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, to be inrolled in Her 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, as in
and by the same, reference being thereunto had, will more fully and at largo
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Seraphin Fauçon, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, that is to say:-
To make soap according to this Invention, two substances only are necessary,
caustic soda water and tallow oil, which is a product largely obtained in
preparing fatty matters in the manufacture of candles. The quantity and
degree of the caustic soda water vary, as does also the quantity of the tallow
oil. In order that the Invention should be well made, it is desirable the soda
water should be strong enough to absorb the tallow oil. The soda water and
the tallow oil can be employed in the proportions and degrees as follows:-
One hundred pounds of caustic soda water at 1-16 degrees, and fifty pounds of
tallow oil. One hundred pounds of soda water at 1.20 degrees, and sixty
pounds of tallow oil. One hundred pounds of soda water at 1-24 degrees, and
seventy-two pounds of tallow oil. One hundred pounds of soda water at 1.27
degrees, and eighty pounds of tallow oil. One hundred pounds of soda water
at 1.30 degrees, and eighty-seven pounds of tallow oil. The quantity of the
combination made with one hundred pounds of soda water at 1.30 degrees to
eighty-seven pounds of tallow oil is far superior to that made with one hundred
pounds of soda water at 1.16 degrees to fifty pounds of tallow oil; it is also
superior to that made of the soda water of the other degrees before mentioned.
Caustic soda water can be employed under 1-16 degrees, also above 1.30.
The quantity of tallow oil mentioned may be also diminished or augmented.
In a word, with caustic soda water and tallow oil the combination or soap can
be made, but the quality will be more or less good according to the propor-
tions employed. To mix these two substances the soda water is to be put in
a barrel or tub, or any other sufficiently large vessel. The soda water should
be employed in a cold state. The tallow oil should be added in a liquid state.
As soon as the tallow oil is added to the soda water, the mixture should be
stirred well together. When it is well mixed it is to be left to repose from
twelve to eighteen hours; then it is to be stirred again, if there is any separa-
tion, and afterwards left for one or several days.

page_text: Having thus described the nature of the Invention, and the manner in
which the same is to be performed, I would have it understood that what I
claim is, the combination of tallow oil and soda water in the manufacture of
soap.
In witness whereof, I, the said Joseph Seraphin Faucon, have hereunto
set my hand and seal, this Ninth day of July, in the year of our Lord
One thousand eight hundred and forty-seven.
