NOW KNOW YE, that in compliance with the said proviso, I, the said
Alexander Fordyce, do hereby declare that the nature of my said Invention,
and the manner in which it is to be performed, is as follows, viz' :-
The nature of my Invention, for which I have a Patent of date the First of
August last, is to obtain from sea salt, salt water, rock salt,. salt springs,
glauber salt, or salt cake, a mineral or fossile alkali, and from vitriolated
tartar a vegitable alkali. The manner of performing these operations is, by
converting salt water, salt springs, sea salt, and rock salt, or compositions of
these, where the saline quality is prevalent, into glauber salt, or salt cake, by
the application of vitriolic acid, or any substance containing it... Mix the glauber
salt, salt cake, or common salt, strong brine, or what can be converted in whole
or in part into salt by chrystilization, evaporation, or calcination,. with double
the quantity of lime, or any other proportion; put them together: in a vault,.
cellar, or any other place covered from the rain; let them stand till part or
the whole of the sea salt, or glauber salt, or salt cake, is decomposed; dissolve
out the alkali, and chrystalize it, or evaporate it to dryness, or, instead of lime,
you may use chalk, or any other calcareous earth or iron, or anything con-
taining iron. Or take sixty pounds of glauber salt, or salt cake, or vitriolated
tartar, ten pounds of iron, ten pounds of charcoal, or they may be used in
various other proportions; melt them together; afterwards pound them,, or
throw them in a lump into forty gallons of water, or into a larger or smaller
quantity of it. Let them digest for twenty-four hours, or a shorter or longer
time; separate the clear solution, evaporate it, and chrystalize the alkali; or
you may use the solution, or evaporate it to dryness; or, instead of the char-
coal, you may use any animal or vegitable inflammable substance, or coal, or.
any inflammable substance which is sufficiently strong to bear the heat, or any

page_text: other substance containing phlogiston; or, instead of the iron, you may use any
calx of iron, or any ore of iron, or anything containing iron, or any other metal
capable of destroying sulphur.
In witness whereof, I, the said Alexander Fordyce, have hereunto set my
hand and seal, this Thirtieth day of November, in the twenty-second
year of the reign of our Sovereign Lord George the Third, by the
grace of God of Great Britain, France, and Ireland King, Defender
of the Faith, and so forth, and in the year of our Lord One thousand
seven hundred and eighty-one.
