; I, JAMES OTAMS, of 2, Horton Villas, Camden Road, Holloway, in
the County of Middlesex, Gentleman, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF MANURE"
to be as follows:-
This Invention consists of treating blood. in its natural state.with
sulphuric or other acid, and then combining therewith phosphates which
act as, dryers, and also the phosphates are acted on by the acid. It
should be stated that heretofore bones and other-phosphates have been
treated with acid; these improvements therefore depend on the combined
process herein stated.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Otanis in the Great Seal Patent Office,

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES OTAMS, of 2, Horton Villas, Camden Road, Holloway, in the
County of Middlesex, Gentleman, send greeting.
WHEREAS Iler most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of October, in the
year of our Lord One thousand eight hundred and fifty-two, in the
sixteenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said James Otams, 1er special
licence that I. the said James Otanis, my executors. administrators,
and assigns, or such others as I, the said James Otamis, my executors,
ádministrators, 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
MANUFACTURE OF MANURE," upon the condition (amongst others) that I,
the said James Otams, by an instrument in writing under my hand
and scal, should particularly describo and ascertain the nature of the
said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the late of the said
Letters Patent.
NOW KNOW YE, that I, the said James Otams, do hereby declare
the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement thereof (that is to say):
This Invention consists of treating blood in its natural state with
sulphuric or other, and then combining therewith phosphates, which act
às dryers, and also the phosphates are acted on by the acid. It should
be stated that heretofore bones and other phosphates have been treated
with acid; these improvements therefore depend on the combined

page_text: process herein described. And in order that my said Invention may be
more fully understood, and readily carried into effect, I-will proceed to
explain the means pursued by me.
I take at the rate of one hundred and fifty gallons, as it is collected
in the slaughterhouse and other places, which I pass through a sieve,
and I break up all the clots or coagulated portions thereof by well
stirring and heating the blood when in a suitable vessel. which I prefer
to be of wood lined with lead. Into such a quantity of blood I stir in,
by preference, seven cwt. of the brown sulphuric acid of commerce,
though other acid may be employed, as when decomposing bones and
mineral phosphates, two cwt of animal charcoal or bone black, and eight
ew of coprolite or mineral phosphate, stirring the combined mass well
till the active action of the acid ceases. The combined mass is then
removed from the vessel, and allowed to dry in bulk, and is then ready
for use as a manure. The manure thus obtained, if desired, may be
mixed with other matters in like manner to what decomposed phosphates
have been before mixed.
Ilaving thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I do
not confine myself to the quantities herein mentioned. But what I
claim is, the mode herein described of manufacturing manure by
combining blood in its natural state with acid and phosphates.
In witness whereof, I, the said James Otains, have hereunto
set my hand and scal, this Eighteenth day of April. in the year
of our Lord One thousand eight hundred and fifty-three.
Witness,
B. GOBEY.
JAMES OTAMS. (L.S.)
