COMPLETE SPECIFICATION filed by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 17th April 1858, pursuant to the 9th Section of

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent Offices, 39,
Rue de l'Echiquier, Paris, in the Empire of France, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED SUB-
STITUTE FOR THE PULVERISED COTTON AND WOOL EMPLOYED IN THE MANUFACTURE
OF FELTED TISSUES, PAPERS, AND OTHER FABRICS," communicated to me from a
foreigner residing abroad, and have petitioned Her Majesty to grant unto me,
my executors, administrators, and assigns, Her Royal Letters Patent for the
same, and made solemn declaration that it is a communication.
NOW KNOW YE, that I, the said Marc Antoine François Mennons, do
hereby declare that the following Complete Specification under my hand and

page_text: seal fully describes and ascertains the nature of the Invention, and the
manner in which the same is to be performed, that is to say) :-
The Invention communicated to me consists in a substitute for the pul-
verised cotton and wool at present employed in the manufacture of felted
tissues, figured papers, and other fabrics. To this end I employ the fibrous
matters obtained by known processes from the filamentous plants in general,
but preferably from the "aloes, phormium tenax," "Manilla hemp," and
the different species of the "agava." These fibrous products being obtained
and thoroughly dried, I reduce them to an impalpable powder by any suitable
mechanical means. The dyeing of the pulverised matter to the required
tint completes the operation.
The powder thus prepared presents a silky appearance, and is applied to
woven tissues, paper for hangings, and other fabrics, in the same way as the
pulverized cotton and wool hitherto employed for the production of felted or
velveted surfaces.
Having thus described the nature of the said Invention, I would have it
understood that I do not restrain myself to any special process of extraction or
general treatment of the fibrous matters; but what I claim is the production
of an impalpable powder from the fibrous constituents of all filamentous
plants, and especially of the species above enumerated, which powder I
employ as a substitute for pulverised cotton and wool, in the manufacture
of felted tissues, papers, and other fabrics, as above described.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereto set my hand and seal, this Seventeenth day of April, One
thousand eight hundred and fifty-eight..
