WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of May, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Thornhill Simpson, Her
special licence that. I, the said Edward.Thornhill Simpson, my execu-
tors, administrators, and assigns, or such others as I, the said Edward
Thornhill Simpson, my 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 law-
fully 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 Edward Thornhill
Simpson, by an instrument in writing under my hand and seal, should
particularly describe 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 date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Thornhill Simpson, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer
tained in and by the following statement thereof (that is to say):
may
This Invention consists in dissolving in sulphuric acid, by means of
heat (preferring free steam), wool, hair, woollen rags, shoddy, and
other waste products of wool for the purposes of manure, and also
in the combination of the solution thus made with bones, burnt bones,
coprolites, and other similar substances for the purposes of manure.
In order that my Invention be fully understood and readily carried
into effect, I will proceed to describe the means pursued by me. I
take, for example, 5 cwt. of wool, hair, woollen rags, shoddy, or other
waste products of wool or hair, and place them in a suitable vessel; I
admit jets of steam for a few minutes, and then pour over the material
3 cwt. of sulphuric acid (concentrated); I again admit steam and stir
the mixture until the material is dissolved; I add about 10 cwt. of
ground bones, coprolites, animal charcoal, or other similar substances,

page_text: and then add, say, 2 cwt. or 4 cwt. of water, according to the quantity
of water which has resulted from the condensing of the steam (where
steam is used). The whole compound is then worked together until
effervescence ceases; the mixture is then to be removed from the
vessel and placed under cover, as heretofore practised when decom-
posing bones or mineral phosphates, and when sufficiently dry the
compound is to be passed through a seive, by which means it becomes
sufficiently fine to be deposited either separately or in combination
with the seed, either by the drill or otherwise.
The quantities of the matters above given may be varied; those given
are for a turnip crop.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I make no
claim to the use of bones, coprolites, animal charcoal, or any other.
similar substance with sulphuric acid in the manufacture of manure.
But what I claim is, the dissolving of wool, hair, woollen rags, shoddy,
and other waste products of wool and hair with acid by means of artificial
heat, and combining the fluid obtained with bones, coprolites, animal
charcoal, or other similar substances for the purposes of manure.
In witness whereof, I, the said Edward Thornhill Simpson, have
hereunto set my hand and seal, this Eleventh day of November,
in the year of our Lord One thousand eight hundred and fifty-

Solicitor,
