Solicitors, at Frankfort-on-the-Main, in the Empire of Germany, for an Inven-
tion of "A NEW COMPOUND TO SERVE AS A BASE OR GROUND FOR OIL OR
OTHER PIGMENTS OR COLOURS."-A. communication from Otto Kall, Partner

Germany.
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office of
the Commissioners of Patents on the 17th January 1882.
FRANK WIRTH of the Firm of Wirth and Company Patent Solicitors at Frankfort
on the Main in the Empire of Germany. "A NEW COMPOUND to SERVE AS A
BASE OR GROUND FOR OIL OR OTHER PIGMENTS OR COLOURS.": [A communi-
cation from Otto Kall, Partner of the Firm of Otto Kall and Company, of Heidelberg,
in the Empire of Germany.].
This invention relates to a new compound to serve as a base or ground for oil or
other pigments or colours.
In carrying the said Invention into practice I mix one (1) part of slaked lime
with ten (10) parts of blood containing fibrine. This mixture is left some time
for the ingredients to work upon one another and then an equal volume of water
is added. A thick precipitate is thus obtained over which the liquid portion
remains for fourteen days during which time the mixture is frequently stirred.
The liquid portion is then carefully removed, a one twentieth (1/20th) part of
permanganate of potash being added, also so much water as will cause the mass
to be of such a consistency that it can be easily applied or laid on. To obviate
ány disagreeable odour turpentine or lavender oil is added. I may sometimes
dispense with the permanganate of potash.
