greeting.
at any
WHEREAS His most Excellent Majesty King George the Fourth, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the First day of August, in the
seventh year of His reign, did, for Himself, His heirs and successors, give and
grant unto me, the said William Davidson, my executors, administrators, and
assigns, His especial licence, full power, sole privilege and authority, that I,
the said William Davidson, my executors, administrators, and assigns, should
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, and exercise and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "A PROCESS OR PROCESSES FOR BLEACHING OR
WHITENING BEES-WAX, MYRTLE-WAX, AND ANIMAL TALLOW;" in which said
Letters Patent there is contained a proviso, obliging me, the said William
Davidson, by an instrument in writing under my hand and seal, particularly to
describe and ascertain the nature of my said Invention, and in what manner
the same is to be performed, and to cause the same to be inrolled in His
Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said recited Letters Patent, as in and by
the same, reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Davidson, do hereby declare the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in the following description thereof (that is to say):-
I combino liquefied bees-wax, myrtle-wax, or animal tallow with oxy-
muriate of lime, oxymuriate of magnesia, or an aqueous solution of either
of them, by stirring the same with a wooden or other spathula or otherwise
in any suitable vessel, and I decomposo these salts by some acid which has
a greater affinity for the lime or magnesia than the oxymuriate acid, such,
for instance, as sulphuric acid. For melting the wax or tallow I use an
iron vessel, lined internally with lead or any other suitable vessel, and heat it
by means of a common furnace, or by steam applied in any way that may
be considered most advantageous. I then combine in this leaden or other
suitable vessel about one hundred and twelve pounds weight of liquefied bees-
wax or myrtle-wax with about an equal weight of a solution of oxymuriate
of lime, heated to the temperature of about boiling water, and having
allowed the mixture to become a little consolidated, I add to it from fifty to
one hundred ounces of sulphuric acid (of tho usual mercantile strength, say
of specific gravity 1-8485) previously diluted with about twenty or thirty
times its weight of water and boil them, whilst agitation with a spathula
or otherwise is employed, until the line is completely separated from the
oxymuriatic acid. The solution of oxymuriate of lime which I employ for
.bleaching bees-wax and myrtle-wax is made by dissolving from about fourteen
to twenty pounds weight of the salt to about one hundred and twelve pounds
weight of water. For bleaching animal tallow I generally use from two to
five pounds weight of the oxymuriate of lime to ono hundred and twelvo
pounds weight of tallow, with a proportionate quantity of water to dissolvo
the salt, dilute the acid, or supply the loss by the subsequent boiling. How-
ever, these proportions of oxymuriate of lime and sulphuric acid for bleaching
becs-wax, myrtle-wax, and animal tallow are not absolute, but a greater
or less quantity of the oxymuriate of lime and sulphuric acid is necessary in
proportion to the greater or less quantity of colouring matter in the wax or
tallow. In those cases where the wax or tallow is not sufficiently bleached
by the process, I repeat it.
In witness whereof, I, the said William Davidson, havo hereunto set
my hand and seal, this Twenty-ninth day of September, in the year
of our Lord One thousand eight hundred and twenty-six.
WILLIAM (L.S.) DAVIDSON.
