The above proportions are those in which I prefer to combine these sub-
stances, but they may be modified according to the work required to be
executed, according to the strength of acid or corrosive salt employed, and
according to the density or nature of the matters to be engraved.
The mixture of these inks is made by putting the component parts in any
suitable vessel, and adding to them the turpentine, in which the caoutchouc or
gutta percha has been previously dissolved.
The first ink I employ to draw or write direct upon stone for lithographic
purposes.
The second ink 1 employ more especially for engraving in relief on stone.
The third ink I employ for engraving in relief on metals, but any of the
three inks may be employed without distinction, according to the nature of
the object to be engraved and the strength of the acids employed.
In witness whereof, I, the said Polynice Auguste Viette, have hereunto
set my hand and seal, this Ninth day of July, in the year of our
Lord One thousand eight hundred and fifty-nine.
POLYNICE AUGUSTE VIETTE (L.S.)
