page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of the Patent Office, Lincoln's Inn, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Letters Patent, under the Great Seal of Great Britain, bearing date at
Westminster, the Fourth day of June, in the second year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Moses
Poole, Her especial licence, full power, sole privilege and authority, that I, the
said Moses Poole, my exors, admors, and assigns, or such other's as I, the said
Moses Poole, my exors, admors, 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, the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF SOAP BY THE APPLICATION OF MA
NOT HITHERTO USED FOR THAT PURPOSE," communicated to me by a certain
foreigner residing abroad; in which said Letters Patent is contained a
proviso that I, the said Moses Poole, shall cause a particular description of
the nature of the said Invention, and in what manner the same is
to be
performed, 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
J

unto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Moses Poole do hereby declare the nature of my said Invention and the
manner in which the same is to be performed are fully described and ascer-
tained in and by the following statement thereof, that is to say:-
The Invention relates to the application of a product of fish obtained by
means of digesting fish as early as possible after they are taken without other
preparation in a papin or such like digester, and in order to give the best
information in my power, I will proceed to explain more fully the means
pursued in order to perform the Invention. But I would first remark that I am
aware that it is not new to employ fish or parts of fish in the making of soap, by
submitting them with alkali to certain processes, but which having nothing to
do with this Invention no description is required in this Specification, and I
have only mentioned the circumstance in order to disclaim all right and title
to the employment of fish or parts thereof in the making of soap when applied
under other circumstances than according to this my Specification. The
apparatus and process of digesting bones in papins or such like digesters being
well known it will not require description here, and as a like process is to be
performed on fish by preference in the state they are taken and as soon after
'as convenient, little description will be required, the Invention not relating to
the process, but to the application of the product in the making of soap. It
may be desirable to state that any description of fish may be used, which can
be obtained in larger quantities and at a cost which will allow of this appli-
cation of the product obtained therefrom, and I may state that herrings and
be placed
sprats are particularly applicable for the purpose. The fish are
in the digester or boiler in the state they are taken, and by means of the
digesting process with steam are to be wholly reduced to a jelly, which, by
preference, should be immediately converted into soap either by itself or
combined with fatty matters at present employed; but it is better to combine
such product with equal weight of tallow or other suitable fatty material for
making soap, the product of fish being gradually incorporated with the tallow
or fatty material in the boiler, and such product of fish, alone or combined
with other fatty matters, are to be converted into soap by alkali, or by any
of the ordinary means now practised in making soap from tallow or other fatty
matters. The digesting process is performed with steam at 50 to 70 lbs. on
the square inch, the fish being covered with water at the commencement, and
the process takes about five to seven hours.

page_text: Having thus described the nature of the Invention, I would have it under-
stood that what I claim is the mode of making soap by the application of a
product of fish obtained by digesting as above described.
In witness whereof, I, the said Moses Poole, have hereunto set my
hand and seal, this Fourth day of December, in the year of our Lord
One thousand eight hundred and thirty-nine.
