be applied to the materials alone, or the solution thereof may be mixed with
gum, starch, flour, farina, or other sizing materials, and so be applied to the
fibrous materials, or it may be mixed in the pulp or "half stuff" in the manu-
facture of paper. The use of the said bydrochlorate improves the appearance
of the materials, and also renders them non-inflammable.

page_text: NOW KNOW YE, that I, the said John Osborne Christian, 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 (that is to say) :-
Our Invention consists in the use and application of hydrochlorate of baryta
or chloride of barium to the sizing, dressing, filling, and stiffening yarns or
fabrics, or in the manufacture of paper. The hydrochlorate of baryta is to be
dissolved and made into a solution of any required strength, and may either be
applied to the materials alone or the solution thereof may be mixed with gum,
starch, flour, farina, or other sizing materials, and so be applied to the fibrous
materials, or it may be mixed in the pulp or "half stuff" in the manufacture
of paper. The use of the said bydrochlorate improves the appearance of the
materials, and may also be applied to render them non-inflamable, and also
acts as an antiseptic in the aforesaid materials for the prevention of mildew
and other fermentative decompositions.
In witness whereof, I, the said John Osborne Christian, have hereunto
set my hand and seal, this Twenty-seventh day of April, in the year
of our Lord One thousand eight hundred and sixty-five.
JOHN OSBORNE CHRISTIAN. (L.S.)
