page_text: LETTERS PATENT to John Box, of 20, Great George Street, West-
minster, Civil Engineer, Edouard Aubertin, of No. 66, in the
Boulevard of Strasburg, in the City of Paris, Gentleman, Leopold
Boblique, of No. 72, in the same Boulevard, Chemist, and Hypolito
Leplay, of Reulle des Meuniers, No. 4, at Bercy, in the City of Paris,
Chemist, for the Invention of "IMPROVEMENTS IN THE DISINFECTION OF
SOLID AND LIQUID MATTERS, SUCH AS NIGHT SOIL, SEWERAGE, EITHER TOGETHER
OR SEPARATELY. GAS. AND OTHER FOUL WATERS."
PROVISIONAL SPECIFICATION left by the said John Box, Edouard
Aubertin, Leopold Boblique, and Hypolite Leplay at the Office
of the Commissioners of Patents, with their Petition, on the
20th January 1875.
We, JOHN Box, of 20, Great George Street, Westminster, Civil
Engineer, EDOTARD AUBERTIN, of No. 66, in the Boulevard of Strasburg,
in the City of Paris, Gentleman, LEOPOLD BOBLIQUE, of No. 72, in
the same Boulevard, Chemist, and HYPOLITE LEPLAY, of Ruelle des.

page_text: Meuniers, No. 4, at Bercy, in the City of Paris, Chemist, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
DISINFECTION OF Solid and Liquid Matters, suCH AS NIGHT SOIL, SEWERAGE,
EITHER TOGETHER OR SEPARATELY, GAS, AND OTHER FOUL WATERS," to be as
follows:-
We employ a soluble alkaline phosphate and a soluble salt of mag-
nesia and oxide of iron or other form of iron. We employ these agents
in different combinations. Wo prefer phosphate of potash or ferruginous
soda prepared by calcination in a reverberatory furnace, the phosphate
of iron with the sulphate of soda, and a soluble salt of magnesia such
the chlorure of magnesium, or any other.
The method of operating with these products is very simple:-The raw
matter as it leaves the reverberatory furnace is washed with the liquids
to be disinfected, which lose the sulphuretted hydrogen contained in them
in their passage through the raw material, which remains deposited in
the state of sulphure of iron. To the water thus deprived of the sul-
puretted hydrogen we add the soluble salt of magnesia. Magnesian
phosphate of ammonia is immediately formed, which precipitates itself,
taking with it the azoted organic matters which are found in the liquids.
After a short time the water becomes clear, and may be run into rivers or
streams without any inconvenience.
To disinfect the thick matters, such as night soil, we reduce the same
products into powder, and we mix them with the thick matter, adding
soluble salt of magnesia. We also employ phosphate of lime dissolved
in chlorhydric acid, and oxide of iron also dissolved in chlorhydric acid.
The cheapest phosphate of lime, such as coprolytes or others, can be
employed dissolved in chlorhydric acid. We also take hydrated oxide of
iron dissolved in chlorhydric acid. We mix these two solutions with the
matter or liquid to be disinfected, and we saturate the excess of acid with
the double carbonate of lime or of magnesia. We can saturate with
chalk, but in this case we add a certain quantity of soluble salt of
magnesia. The deposit of magnesian phosphate of ammonia obtained
by the treatment with ferruginous phosphate of soda can be dried in
the air and reduced into powder, and is a very powerful manure, con-
taining not only ammoniacal magnesian phosphate, but also azoted
organic matters, which the ammoniacal magnesian phosphate has taken
down with it in precipitating itself. It can also be used for the extraction

can be allowed to run into rivers without any inconvenience to public
health, and the residue forms a rich and valuable manure.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Box, Edouard Aubertin, Leopold Boblique,
and Hypolite Leplay in the Great Seal Patent Office on the
16th July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
Box, of No. 20, Great George Street, Westminster, Civil Engineer,
EDOUARD AUBERTIN, No. 66, in the Boulevard of Strasburg, in the City
of Paris, Gentleman, LEOPOLD BOBLIQUE, of No. 72, in the same
Boulevard, Chemist, and HypOLITE LEPLAY, of Reulle des Meuniers,
No. 4, at Bercy, in the City of Paris, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her.
Letters Patent, bearing date the Twentieth day of January, in the year
of our Lord One thousand eight hundred and seventy-fivo, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Box, Edouard Aubertin,
Leopold Boblique and Hypolite Leplay, Her special licence that we,
the said John Box, Edouard Aubertin, Leopold Bobliquo, and Hypolito
Leplay, our executors, administrators, and assigns, or such others as we,
the said John Box, Edouard Aubertin, Leopold Boblique, and Hypolito
Leplay, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN THE DISINFECTION OF SOLID AND LIQUID MATTERS, SUCH AS
NIGHT SOIL, SEWERAGE, EITHER TOGETHER OR SEPARATELY, GAS, AND OTHER FOUL
WATERS," upon the condition (amongst others) that wc, tho said John
Box, Edouard Aubertin, Leopold Boblique, and Hypolite Leplay, our
executors or administrators, by an instrument in writing under our, or
one of our, or their, or one of their hands and scals, should particularly.
describe and ascertain the nature of tho said Invention, and in what

page_text: manner the same was to be performed, and cause the same to be filed
in the Great Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Box, on behalf of myself
and the said Edouard Aubertin, Leopold Boblique, and Hypolite Leplay,
do hereby declare the nature of our said Invention, and in what
manner the samo is to be performed, to be particularly described
and ascertained in and by the following statement :—
We employ a soluable phosphate and a soluable salt of magnesia and
oxide of iron or other form of iron. We employ these agents in different :
combinations. We prefer phosphate of potash or ferruginous soda,
which is prepared by calcination in a roverberatory furnace of tho
phosphure of iron with the sulphato of soda or potash, which thus
produces the ferruginous phosphato of soda or potash. To this wo add
any soluble salt of magnesia, such as the chlorine of magnesia.
The method of operating with these products is very simple:-Tho
raw ferruginous phosphate of soda or of potash, without further pre-
paration, in the state in which it leaves the reverberatory furnace, is
washed with or is thrown into the liquids to be disinfected, which removes
the sulphuretted hydrogen contained in them in their passage through
or mixing with the raw material; thus the two products may be used
together or separately. The ferruginous phosphate being first used, the
ammonial water, urine, or gas water is thus deprived of the sulphuretted
hydrogen it contains. The soluble salt of magnesia is then added, and
magnesian phosphate of ammonia is immediately formed, which pre-
cipitates itself, taking with it the azoted organic matters which are found
in the liquids. After a short time tho water becomes clear, and may bo
run into rivers or streams without any inconvenience.
To disinfect the thick or semi-liquid matters, such as night soil, wo
reduce the ferruginous phosphate of soda or potash into powder, and wo
mix them with the thick or semi-liquid matter, adding a soluble salt of
magnesia. We also in certain cases employ phosphato of lime dissolved
in chlorhydric acid, and oxide of iron also dissolved in chlorhydric acid;
the cheapest phosphate of lime, such as coprolytes or others, can be
employed dissolved in chlorhydric or other acid. We also take hydrated
oxide of iron dissolved in chlorhydric or other acid. We mix these two
solutions with the matter or liquid to be disinfected, and we saturate the

page_text: -
excess of acid with the double carbonate of lime or of magnesia. We
can saturate with chalk, but in this case we add a certain quantity of
soluble salt of magnesia. The deposit of magnesian phosphate of
ammonia obtained by the treatment with ferruginous phosphate of soda
can be dried in the air and reduced into powder, and is a very powerful
manure, containing not only ammoniacal magnesian phosphate but also
azoted organic matter which the ammoniacal magnesian phosphate has
taken down with it in precipitating itself. It can also be used for the
extraction of ammonia from liquids containing ammonia. The liquids
proceeding from theso different treatments can be allowed to run into
rivers without any inconvenience to public health, and tho residue forms
a rich and valuable manure.
In witness whereof, I, the said John Box, on behalf of myself and
the said. Edouard Aubertin, Leopold Boblique, and Hypolite
Leplay, have hereunto set my hand and seal, this Twelfth day of
July, in the year of our Lord One thousand eight hundred and
soventy-five.
