the Commissioners of Patents, with his Petition, on the 19th December
1860. A communication from abroad by Bénoit Marie Alexandre
Glénard and the Société Coignet père, Fils et Co., of 33, Boulevard
Saint Martin, Paris, France.
I, MICHAEL HENRY, of 84, Fleet Street, in the City of London, Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF COLOURS APPLICABLE FOR VARIOUS USES IN ARTS AND
MANUFACTURES," communicated to me from abroad by Bénoit Marie Alexandre
Glénard and the Société Coignet père, Fils et Co., of 33, Boulevard Saint
Martin, Paris, France, to be as follows:-
The object of this Invention is the manufacture of colours suitable for
printing textile fabrics and paper hangings, for oil and varnish painting, for
the manufacture of crayons, and various other purposes.
By means of this Invention colours are produced in a solid state, and they
may be combined with oil, varnish, size, or other vehicle, or a deliquescent
agent, or they may be otherwise treated and used or applied in any desirable
manner.
I propose to dye mineral and earthy matters, after first adapting them for
the purpose, by what I call animalization or vegetalization. Mineral and
earthy, neutral or inert matters are not naturally suited for taking dyes
or colours from dyeing liquors or baths like textile fabrics or animal and
vegetable materials, but they may be adapted for the purpose by first sub-

page_text: jecting them to animalization or vegetalization, that is to say, I effect their
intimate union or combination, or union, molecule by molecule with some
animal or vegetable substance capable of receiving dye. Various agents and
methods may be adopted to carry this into effect.
Gelatine or animal or vegetable albumen are examples of soluble sub-
stances which may be used for rendering mineral and earthy matters capable
of taking a dye, for instance, the mineral substance may be pulverized and
diluted in a solution of albumen and brought into a paste, which is dried, by
which means the mineral molecules will be encased in a sort of albuminous
varnish; but I do not confine myself to this agent or method.
I propose to fit bones for being dyed, and hence manufactured into colours,
by subjecting them to heat or treating them in a digester. I submit bones to
the prolonged action of water in a digester at an elevated temperature,
whereby they will be fitted for receiving dye, and will take the reds and
violets of aniline and various other colours, and produce solid colours in those
and many other hues. The bones may be dyed by placing them whole or
pulverized, hot or cold, in a solution of the dye, when the liquid will become
decolorized, and the colour be communicated to the bones. The treatment in
the digester, moreover, adapts them for pulverization. The phosphate of the
bones is supposed an important agent in the colouring process. I propose to
apply the action of phosphate for the purpose of precipitating colour, or as
means of producing adaptability for the taking of dye or colour.
