I, LEOS ANTOINE BADIN, of Number Nine, New Ormond Street, in
the County of Middlesex, Civil Engineer, do hereby declare the nature
of the said Invention for "A NEW OR IMPROVED METHOD OF DEODORIZING
HUMAN EXCREMENTITIOUS MATTERS, AND OF ITS MANUFACTURE INTO FARM MANURE
SUITABLE FOR ALL DESCRIPTIONS OF AGRICULTURAL PURPOSES AND TO ALL LOCALITIES,'
to be as follows:-
The production of an apparatus or arrangement which, in conjunction
with a chemical composition or compound, will rapidly disinfect human
excrements deposited therein, filter and discharge the fluid portion
thereof, and preserve those parts of such excrementitious matters that
are useful for agricultural purposes, and which may be afterwards easily.
and cheaply manufactured into a dry rich manure, a kind of human
guano, possessing similar properties and advantages to those of Peruvian
guano, and which will at the same time from a chemical point of view
contain all the fertilizing elements of farm yard manure.

page_text: The means by which I propose to attain the said object of my
Invention are as follows:-I take a cylindrical outer case of galvanized
sheet iron or other suitable material, varying in size according to cir-
cumstances and requirements, closed at the bottom end and having
a domed telescopic lid somewhat similar in form to the lids of ordinary
saucepans, and having a circular hole in the top for the admission of
a pipe through which the excrementitious matters are to pass. Within
the said outer case I place a smaller cylindrical case without either
bottom or lid, leaving a space all around between the two cases of about
one-third of an inch, more or less, according to circumstances and the
size of the cases. This second or inner cylindrical case I make of thin
wood, sheet iron, or other suitable material, and perforate the same
freely all over its surface with holes of different sizes. I cover this
cylinder with lead paint, and pay the whole of it with tar or other
suitable dressing. Within the said second or inner cylinder I place
a skeleton case or mould, in form or shape a truncated cone without
bottom or top made of strips of wood or of iron hoops and ribs, and I
dress it with lead paint payed over with tar. The dimensions of this
mould are so arranged as to leave a space of about half an inch, more
or less, between the top and the upper edge of the said second or inner
cylinder. The said mould is about four-tenths of the diameter of this
second cylinder at the top, and about seven-tenths at the bottom. The
space between the conical case or mould and the inner cylinder I fill
with house vegetable refuse, forage, and such like substances saturated
with a chemical compound formed or composed of some or all of the
following chemical agents and neutral salts, sulphuric, chloric, phos-
phoric, and nitric acids, the sulphates and chlorides of lime, iron,
manganese, and zinc in quantities or bulk varying according to the
nature of the excrementitious matters and the locality wherein my
improved apparatus is placed.
The average quantities of acids and mineral salts used and employed
for every ninety pounds weight of house vegetable refuse, forage, and
such like substances are as follows:-
When used in barracks.-Three pints of acids, eighteen pounds of
metallic salt, two pounds of chloride lime.
In mechanics' houses.-Two and a half pints of acids, fifteen pounds
of metallic salt, one pound chloride lime.

page_text: In the houses of better socially placed persons.-One and a half pint
acid, twelve pounds metallic salt.
The fluid portion of the excrementitious matters deposited in the
mould speedily filter through the chemical compound, leaving only the
solid and useful portions in the said mould, the whole being at once
totally disinfected by the absorption or decomposition of the noxious
gases and vapours, or exhalations arising therefrom.
A waste pipe is fixed in the bottom of the outer case to carry off the
filtered fluids.
By the general application of my Invention the sanitary condition
of houses and towns will be greatly improved; the time and cost of
drying the solid matters will be considerably reduced and also the
carriage thereof.
