Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN EVANS,
of Kensington, in the County of Middlesex, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Seventh day of August, in the ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Evans, my exors, adññiors, and assigns, Her especial licence, full power,
sole privilege and authority, that I, the said John Evans, my exors, admors,
and assigns, or such others as I, the said John Evans, my exors, admors, or
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, my Invention of "A NEW PERAZOTIC PRODUCT,
AND ITS APPLICATION TO THE ARTS;" in which said Letters Patent is contained a
proviso that I, the said John Evans, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
to be inrolled in Her said Majesty's High Court of. Chancery within six
calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said John Evans, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained in and by the following statement thereof, that is
to say:

page_text: First, the animal matters or substances which enter into the composition of
my manner are as follows:-Muscular fibre, flesh, blood, serum, sour milk,
old skins, the flesh and bones of fish, urine, horn, old woollen rags, the refuse
of soapboilers, of slaughterhouses, and of tallow and candle manufactories.
Secondly, the vegetable matters are humus, rotten or decayed wood, the pro-
duce of dunghills, of stables, the waters of starch manufactories, of manufactures
of prussiates, of dyers' establishments, of brewers, of distillers, of refiners, and
the ammoniacal and other liquors of gas manufactories:
Thirdly, the mineral substances are ashes containing potash, soda, phosphates,
and silicates.
MODE OF MAKING MANURE.
To convert animal matters into manure, and render them of easy transport
without creating a nuisance or affecting the public health, they are first treated
with a decoction of oak bark, combined with about one tenth of its volume of
pyrolignite of iron of commerce. This mixture is put into suitable vessels, and
the muscular parts of animals, fish, blood, the remains of skins and entrails, are
introduced into such vessels, and allowed to stand for three days, after which
they are taken out and dried, either in the open air or by applying heat, in
which state of dryness these matters are devoid of all fœtid odour, and can be
reduced to powder with ease. The decoction of oak and pyrologeneous acid
may be replaced by sulphate of iron and alum, dissolved in equal parts in
water, or by a mixture of naptha, to which a slight quantity of nitric acid is
added, and which is saturated with lime. With regard to feculent matters
mixed with urine I obtain the same result, by pouring into cesspools or sewers,
or conveniences, in small quantities, either a decoction of oak bark joined to a
solution of sulphate of iron and alum or naptha, combined with lime, and treated
with nitric acid, with a tenth of its weight of sulphate of iron. Before, however,
introducing the disinfecting agent into cesspools, &c., into the open part of
such cesspools liquid muriatic acid may be injected in small quantities at a
For pure urine, or containing a slight proportion of feculent matter, a
little of the disinfecting agent should be added to it before taking it from
where it may be, in order to carry off the foetid gases; it is then introduced into
a vessel provided with a lid in the shape of the top of a still, with a tube to carry
the gasses to the bottom of a butt or vessel two thirds filled with sulphuric acid,
diluted with water; and to every one thousand quarts of the liquid contained in
the vessel above mentioned ten pounds of the following composition is added:-
Six parts of water, one part and a half of sulphuric acid of sixty-six degrees, and
one part of fresh bones, the whole to be boiled together in a leaden boiler for
seven or eight hours. When this matter has been introduced into the
time.
