Park, in the County of Middlesex, for an Invention of "A NEW OR

PURPOSES."
PROVISIONAL SPECIFICATION left by the said Nicholas Chevalier at the
Office of the Commissioners of Patents on the 6th December 1880.
NICHOLAS CHEVALIER, of No. 5, Porchester Terrace, Hyde Park, in the County
of Middlesex. "A NEW OR IMPROVED LIGHT-PRESERVING COMPOSITION OR
MEDIUM FOR ARTISTIC PURPOSES."
My Invention relates to a new or improved composition or medium for preserving
and protecting any high lights or any portion of a water color painting so as to
resist any washes of color applied over it.
It consists in mixing together benzine, benzoline, or paraffin, india rubber or
gutta percha, and bees wax, stearine, or spermaceti, until of proper consistency for
use either as a solid or in a fluid form.
When used as a fluid this compound is applied to the lights or colors of a water
color painting with a steel pen, quill, or brush, and when used as a solid it is
applied in the form of a crayon.
The approximate proportions of the above named ingredients are benzine,
benzoline, or paraffin, 1 ounce; india rubber or gutta percha, 1 dram; beeswax,
stearine, or spermaceti, 2 drams. These may be either used singly or in combination
and the proportions varied as found most suitable.
This compound may be made either colored or not and used upon paper, leather,
wood, marble, glass, or any other surface.
