TO ALL TO WHOM THESE PRESENTS SHALL COME, I,

of our Lord One thousand eight hundred and fifty-three, in the seven-

page_text: teenth year
of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Auguste Castets, Her special licence that I,
the said Auguste Castets, my executors, administrators, and assigns, or
such others as I, the said Auguste Castets, 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 "AN IMPROVED COMPOSITION FOR
CURING DISEASES IN THE FEET OF ANIMALS," upon the condition (amongst
others) that I, the said Auguste Castets, by an instrument in writing
under my hand and seal, 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- Auguste Castets, 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):
This composition consists of.a mixture of the following substances:-
Animal oil, gum copal or resinous gum, tar, the solution of an alkali,
wax, tallow.
And in order that the manner of manufacturing the said compo-
sition may be most fully understood and readily carried into effect, I
will proceed to describe the manner in which I prefer to mix the above
ingredients, and to state the proportions in which I prefer to employ
the same, which are as follows:-
.
Animal oil, and by preference that extracted
from the feet of oxen, sheep, or horses
Gum copal, or resinous gum.
Tar
An alkaline solution (either potash or soda)
Wax
60 part
.5 do.
10. do.
10 do.
5 do..
Talla

page_text: The alkaline solution should mark about 10 degrees of Baumé,
and should be prepared by boiling therein a small quantity of linseed.
I first melt the gum copal in a suitable vessel, and when it is com-
pletely liquified I run the tar (which should be by preference a tar re-
sulting from the distillation of a resinous wood). In another vessel
I melt the wax and the tallow to which I add the oil and mix the whole
well together; afterwards I add the alkaline solution, and again mix.
I lastly stir together the contents of the two vessels.
Having thus described the nature of my composition, and the manner
of preparing the same, I would have it understood that I do not con-
fine myself to the proportions described, but what I claim is, the pre-
paration of the above composition.
In witness whereof, I, the said Auguste Castets, have hereunto set
my hand seaal, this Eleventh day of May, in the year of our
Lord One thousand eight hundred and fifty-four.
Witness,
