Manufacturers.
Scaled the 5th January 1867, and dated the 10th November 1866.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 10th November 1866, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852..
TO ALL TO WHOM THESE PRESENTS. SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 38, Porchester
Terrace, Bayswater, in the County of Middlesex,. Patent Agent,, send
greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED
MANURE OBTAINED BY AN IMPROVED PROCESS OF PURIFYING FOUL WATERS," a
communication from Jules Houzeaur and Eugène Devedcix, both resident at

page_text: 72, Boulevard Sébastopol, Paris, in the Empire of France, Manufacturers,
and have petitioned Her Majesty to grant unto me, my executors, adminis-
trators, 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 Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the Invention, and the manner
of bringing the same into effect, that is to say:-
The Invention communicated to me relates to an improved process of using
mineral substances or such as are of vegetable origin combined with lime in
order to obtain the purification of those waters which come from factories,
households, closets, gutters, and sewers, in fine, all such foul waters as are
now thrown away as useless. To effect this the following materials are
used:-
1º. The lignites in general (a production of vegetable origin) arising from
the decomposition of plants which have not entirely undergone the coal trans-
formation, friable or not, whatever may be the colour.
2º. An imitation of the lignites, which may be obtained by means of pit
coal in a pure state, the ashes of said pit coal after burning or the coke
resulting from the carbonisation of this pit coal, and finally, charcoal and all
artificial coals, sulfate of iron, commonly called copperas.
3°. Clay, commonly known as potter's clay, which is mixed with the sub-
stances indicated in the above-mentioned paragraph.
4°. Lime, which must always be used concurrently with one of the above-
mentioned substances, and after being slacked.
The proportion of lignites to be employed varies between 4 and 6 drams
or thereabouts (about 2 to 3 grammes) per quart, and that of the lime
between 2 and 6 drams or thereabouts (about 1 to 3 grammes) also per
quart, according to the nature of the waters to be treated; that of the pit
coal, of the ashes, coke, and all natural and artificial charcoals, is from 4 to 12
drams or thereabouts (about 2 to 6 grammes) according to their richness,
and lime white is always added in the above given proportions.
One of the above-mentioned products is made use of either by throwing it
into the water to be purified, or by reducing it into a dissolution, the density
of which varies according to the greater or lesser purity of the waters to be
treated, always adding lime white to it. The two mixtures thus being performed
a coagulation takes place, which settles almost immediately, leaves a sediment
or residue, which has seized upon the organic matter, and the water becomes
limpid.

page_text: The deposit or residue being properly dried may be used to great
advantage for agricultural purposes as manure, the proportion of which varies
according to the greater or lesser density of the liquid purified.
Having now described and ascertained the nature of the said Invention,
and the manner of carrying the same into effect, what I would claim is an
improved manure obtained by the improved process of the purifying of foul
waters, substantially as herein above set forth and described.
In witness whereof, I, the said Henri Adrien Bonneville, have hereto
set my hand and seal, this Third day of November, in the year of
our Lord One thousand eight hundred and sixty-six.
H. BONNEVILLE. (J.S.)
