TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY BALMAIN, of Pocket Nook Chemical Works, Saint Helen's, in the
County of Lancaster, Manufacturing Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by-Her Letters
Patent, bearing date the Fourth day of December, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Henry Balmain, Her special license that I, the said William
Henry Balmain, my executors, administrators, and assigns, or such others as I;
the said William Henry Balmain, 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." IMPROVE-
MENTS IN THE MANUFACTURE OF POTASH AND SALTS OF POTASH," upon the condition
(amongst others) that I, the said William Henry Balmain, 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 William Henry Balmain, do hereby
déclare the nature of my said.Invention, and in what manner the same is to be
performed, to be.particularly described and ascertained in and by the following
statement (that is to say) :
This Invention of "Improvements in the Manufacture of Potash, and Salts
of Potash.consists in the employment of the spent bark or other-woody fibre
from which tannin-or-coloring-matter-has been extracted as a source of potash
and its salts. My method of carrying out my Invention consists in incinerating
the spent bark or other woody fibre, or the charcoal obtained therefrom, and,
then lixiviating the residuum, after which the salts may be obtained from the
solution in any of the well known manners. Or the residuum may be applied
without lixiviation direct to the formation of salts of potash by the addition of
suitable acids according to the particular salts required. Or the residuum

page_text: containing the impure potash may be applied to the uses for which salts of
potash may be required.
Having now described my Invention of "Improvements in the Manufacture
of Potash and Salts of Potash," and having explained the manner of carrying
the same into effect, I claim as the Invention secured to me by Letters Patent,
as aforesaid, the use of spent bark or other woody fibre, from which tannin or
coloring matter has been extracted as a source from which potash or the salts
of potash.may be obtained..
In witness whereof, I, the said William Henry Balmain, have hereunto
set my hand and seal, the Third day of June, in the year of our Lord
One thousand eight hundred and sixty-two.
Witness,
EDWIN NOLAN.
