from Louis Marie Amand Achille de Courson de la Villeneuve, (Brigadier-

residing at Caen (Calvados), in the Empire of France.
Sealed the 16th May 1862, and dated the 12th December 1861.
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 12th December 1861, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852..
TO ALL TO WHOM THESE. PRESENTS SHALL COME, J, MARC
ANTOINE FRANÇOIS MENNONS, of Furnival's Inn, London, E.C., send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED MEANS OF
DEFECATING, AND PURIFYING CANE, AND OTHER SACCHARINE JUICES," (communicated
by Louis Marie Amand Achille de Courson de la Villeneuve, (Brigadier
General in the French Army, and Commander of the Legion of Honour,)
resident at Caen (Calvados), in the Empire of France), 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

page_text: and 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 the application of albumen
to the defecation and purification of cane, beetroot, and other saccharine juices.
To this end the albumen (say the white of eggs), in the proportion of about
one ounce (avoirdupois) to seven hundred and fifty (750) gallons of the juice,
is placed in the vat, which receives the latter as it flows in its raw state from
the mill or other source, the mass being stirred from time to time. When
the vat is nearly filled, the juice thus albumenised is left to repose for about
ten minutes, and is afterwards boiled in the ordinary way without any addition
of lime or other reagent.
When in the evaporating batteries the liquid mass should be lightly
sprinkled with cold water in order to separate from the scums the extraneous
matters which may still be present.
The syrups proceeding from the first sugar should be reboiled without
addition of lime or other substance, having already been freed by 'the albumen
in the opening process from all impurities capable of injuriously affecting the
crystallisation.
Having now described the nature of the said Invention, and the manner of
carrying it into effect, I would have it understood that I do not confine
myself to the precise details of proportion and manipulation above laid down,
as these may obviously be modified without deviating from the principal or
main features of the improved process; but what I claim, and desire to
secure by Letters Patent is the application of albumen, substantially as herein
set forth, to the defecation and purification of cane, beetroot, and other
saccharine juices.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereto set my hand and seal, this Ninth day of December, in the
year of our Lord One thousand eight hundred and sixty-one.
