Sealed the 2nd December 1859, and dated the 7th June 1859.
PROVISIONAL SPECIFICATION left by the said William Bryer Nation
at the Office of the Commissioners of Patents, with his Petition, on the
7th June 1859.
I, WILLIAM BRYER NATION, of Union Row, Union Bridge, Rotherhithe,
London, Analytical Chemist, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF SUPERPHOSPHATE OF LIME,"
to be as follows:-
I submit phosphates composed of the ordinary materials, namely, bone ash,
animal charcoal, and coprolites to the action of sulphuric acid and muriatic
acid or their equivalents, sulphuric acid gas and muriatic acid gas, either
separately or in any combination thereof. To make the gases combine with
the phosphate materials, I place the materials in a suitable chamber with
shelves on which they are spread, and if necessary moistened with steam or
water, using the ordinary iron pot or cylinder for muriatic acid, and the
ordinary kiln for burning the sulphur. I then dry the superphosphate of lime
thus produced in a suitable chamber by means of hot air not above 212 or
below 150 degrees Fab.

TO ALL TO WHOM THESE PRESENTS SHALL COME,, J, WILLIAM
BRYER NATION, of Union Row, Union Bridge, Rotherhithe, London, Analytical
Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of June, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Bryer Nation, Her special licence that I, the said William
Bryer Nation, my executors, administrators, and assigns, or such others as
I, the said William Bryer Nation, 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 MANUFACTURE OF SUPERPHOSPHATE OF LIME," upon the
condition (amongst others) that I, the said William Bryer Nation, 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 William Bryer Nation, do hereby
declare 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):-
:-
I submit phosphates composed of the ordinary materials, namely, bone asb,
animal charcoal, and coprolites to the action of sulphuric acid and muriatic
acid or their equivalents, sulphuric acid gas and muriatic acid gas, either
separately or in any combination thereof. To make the gases combine with
the phosphate materials, I place the materials in a suitable chamber with
shelves, on which they are spread, and, if necessary, moistened with steam or
water, using the ordinary iron pot or cylinder for muriatic acid, and the
ordinary kiln for burning the sulphur. If necessary, I dry the superphosphate

page_text: of lime thus produced in a suitable chamber by means of hot air from about
150 to 212 degrees Fah.
The following are the ingredients and proportions of the same that I use to
make superphosphate of lime with a large per-centage of soluble phosphates,
namely, 1 ton of coprolites, 1 ton of bone ash, 1 ton of sulphuric acid, or its
equivalent of sulphuric acid gas, 1 ton of muriatic acid, or its equivalent of
muriatic acid gas. Or I use the following phosphate materials, bone, ash
bone, animal charcoal, coprolites, &c., with sulphuric acid and muriatic acid,
or sulphuric acid gas and muriatic acid gas, or the said phosphate materials
with sulphuric acid gas and muriatic acid; or the same with muriatic acid
gas and sulphuric acid, or the same with muriatic acid gas, sulphuric acid gas,
or muriatic acid singly. I place the materials in a suitable chamber with
shelves on which they are spread, and, if necessary, moistened with steam or
water to make the gas or gases combine with the phosphate materials. Also, if
necessary, I dry the superphosphate of lime in a suitable chamber by means of
hot air caused to pass through it, heated from 150 to about 212 degrees Fah.
Having thus described the nature of my said Invention, and the manner in
which the same is to be performed, I desire it to be distinctly understood that
I do not confine myself to the exact proportions of the said ingredients as
herein described, nor to the exact heat of the air introduced into the chamber,
though from experience I have found the same to be very effective; but I
claim as my Invention, the manufacture of superphosphate of lime from the
materials, and in the manner herein described, or any modification thereof.
In witness whereof, I, the said William Bryer Nation, have hereunto
set my hand and seal, this Fifth day of December, in the year of our
Lord One thousand eight hundred and fifty-nine.
Signed, sealed, and delivered by the within-
named William Bryer Nation in the
presence, of
EDWARD T. HUGHES,
123, Chancery Lane, London.
