Year: 1863

page_text: LETTERS PATENT to Robert Charles Furley, of Edinburgh, in the County
of Mid Lothian, for the Invention of "IMPROVEMENTS IN THE PREPARATION
OF CASTOR AND OTHER OILS FOR MEDICINAL USE."
Sealed the 18th November 1868, and dated the 8th June 1863.
PROVISIONAL SPECIFICATION left by the said Robert Charles Furley
at the Office of the Commissioners of Patents, with his Petition, on
the 8th June 1868.
I, ROBERT CHARLES FURLEY, of Edinburgh, in the County of Mid Lothian,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE PREPARATION OF CASTOR AND OTHER OILS FOR MEDICINAL USE," to be as
follows:-
The mode in which the improvements are proposed to be effected is by
thoroughly mixing a quantity of castor or other oil with a portion of finely-
ground sugar, arrowroot, flour, or anything containing any of these or similar
substances, with a portion of powdered gum or starch, and with or without a
portion of tartaric acid. The proportions in which these several ingredients
are used is, six drachms of sugar, two drachms of starch, and two grains of
tartaric acid, to one ounce of oil; but any other quantities may be preferred
in order to adapt them to the tastes of different consumers.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
CHARLES FURLEY, of Edinburgh, in the County of Mid Lothian, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of June, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Robert Charles Furley, Her special licence that I, the said Robert
Charles Furley, my executors, administrators, and assigns, or such others
as I, the said Robert Charles Farley, my 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, an Invention for
"IMPROVEMENTS IN THE PREPARATION OF CASTOR AND OTHER OILS FOR MEDICINAL
USE," upon the condition (amongst others) that I, the said Robert Charles
Furley, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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 immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Robert Charles Furley, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
The mode in which the improvements are proposed to be effected is by
thoroughly mixing a quantity of castor or other oil with a portion of finely
ground sugar, arrowroot, flour, or anything containing any of these or similar
substances, with a portion of powdered gum or starch, and with or without a
portion of tartaric acid. The proportions in which these several ingredients
are used is, six drachms of sugar, two drachms of starch, and two grains of
tartaric acid, to one ounce of oil; but any other quantities may be preferred
in order to adapt them to the tastes of different consumers.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.

page_text: The proportions of the ingredients above mentioned, combined with castor
or other oil, for medical uses, may be varied, but I prefer the following:-
Six drachms of loaf or refined sugar; two drachms of starch, arrowroot, or
other of the substances above mentioned, and two grains of tartaric acid.
These matters are combined with castor or other oil in the following manner :
-The loaf or refined sugar, the arrowroot, and the tartaric acid, are each
separately ground as finely as possible. These substances are then mixed in
the proportions above mentioned, and then passed through a fine hair or wire
sieve. Equal parts of the mixture as now prepared, and castor or other oil,
are then constantly stirred together till incorporated or intimately mixed or
combined.
In some cases I do not employ arrow root or starch or similar substance,
because, if the oil to be prepared for medicinal use be an animal oil, or an oil
having a disagreeable, or pungent, or fishy taste or smell, the disagreeable
taste or smell is more perceptible when mixed with arrow root, starch, or
similar substance.
In some cases also I do not employ tartaric acid, but use citric acid or
malic acid instead, because these acids are of a similar nature and have a
similar taste.
And I sometimes use lime water, together with an essential or flavouring
oil or oils, because when the oil to be prepared for medicinal use has a dis-
agreeable taste or smell, which taste or smell is not rendered less perceptible
by the addition of arrow root or similar substance, the naseous smell is
rendered less perceptible by adding oil of cassia or other similar flavouring oil
or oils, and the naseous disagreeable taste is rendered less perceptible by
mixing it with lime water or other alkali or alkaline water.
The proportions of the above ingredients in preparing for medicinal use an
animal oil may be varied, but I prefer the following:-One ounce of finely-
powdered loaf sugar, three ounces of lime water, half a drachm of oil of cloves,
half a drachm of oil of cassia, to four ounces of the animal oil.
In witness whereof, I, the said Robert Charles Furley, have hereunto
set my hand and seal, this Fifth day of December, in the year of our
Lord One thousand eight hundred and sixty-three.
ROBERT CHARLES FURLEY. (L.S.)
