page_text: LETTERS PATENT to John Lott, of Hackney, in the County of
Middlesex, for the Invention of an "IMPROVED COMPOSITION FOR PRE-
VENTION OF POTATOE DISEASE, APPLICABLE ALSO FOR DRESSING AND MANURING
LAND BAD AMHED ADAM D 29
Sealed the 11th May 1875, and dated the 14th November 1874.
PROVISIONAL SPECIFICATION left by the said Jolin Lott at the
Office of the Commissioners of Patents, with his Petition, on the
14th November 1874.
I, JOHN LOTT, of Hackney, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVED COMPOSITION FOR
PREVENTION OF POTATOE DISEASE, APPLICABLE ALSO FOR DRESSING AND MANURING
LAND FOR OTHER AGRICULTURAL PURPOSES," to be as follows:-
This Invention has for its object principally the prevention of the
potatoe disease, and to effect this I use a composition made of the
following ingredients mixed in suitable proportion, namely:-Coal tar,
carbolic acid, vegetable bitumen, nitrate of soda, potash, the dust from
chemical factories, and as a base I use superphosphate refuse of bone

page_text: boilers, meat dried into powder, sugar scum, ashes from drying herrings,
cocoa-nut fibre, vegetable ashes made by burning flag and roots grown
on London sewage in a reservoir; this material contains much potash.
The whole of these ingredients I prefer to use in making the composition,
though some may be dispensed with, and the composition made accord-
ingly, though I prefer to use the whole of them. I prefer to use this
composition by applying it in the drills or sowing furrows just before
planting.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Lott in the Great Seal Patent Office on the
13th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN LOTT,
of Hackney, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Lott, Her special
licence that I, the said John Lott, my executors, administrators, and
assigns, or such others as I, the said John Lott, 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 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 " IMPROVED COM-
POSITION FOR PREVENTION OF POTATOE DISEASE, APPLICABLE ALSO FOR DRESSING
AND MANURING LAND FOR OTHER AGRICULTURAL PURPOSES," upon the condition
(amongst others) that I, the said John Lott, my executors or admini-
strators, by an instrument in writing under my, or their, or one of their
hands and seals, 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.

page_text: NOW KNOW YE, that 1, the sand on Lott, de fereby actuare
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement :—
This Invention has for its object principally the prevention of potatoe
disease, and to effect this I use a composition of the following ingredients
mixed in suitable proportions, namely:-Coal tar, carbolic acid, vegetable
bitumen, nitrate of soda, potash, flue dust from chemical factories, and
mix these with superphosphate of lime, refuse of bone boilers, meat dried
into powder, sugar scum, ashes from drying herrings, burned cocoa-nut
fibre, vegetable ashes made by burning flag and roots grown on London
sewage in the reservoir (this last material contains much potash). The
whole of these ingredients I prefer to use in making the composition-
(though some may be dispensed with, as for instance, of coal tar, carbolic
acid or vegetable bitumen, any one or two may be used, and of nitrate
of soda and potash one may be used). In regard to the other substances
particular directions are herein-after set forth, and the composition made
accordingly, though I prefer to use the whole of them. I prefer to use
this composition by applying it in the drills or sowing in the furrows
just before planting.
An example of how I carry my Invention into practical effect is
this :-I take one part of coal tar, one and a quarter part of carbolic
acid, one part of vegetable bitumen, one part of nitrate of soda, one part
of potash, one and three-quarters part of superphosphate, and forty-three
parts composed of all or some of the following substances, namely:-
The dust from chemical factories, refuse of bone boilers, meat dried into
powder, sugar scum, ashes from drying herrings, burned cocoa-nut fibre,
and vegetable ashes. These forty-three parts above mentioned may
however consist either of any one of these substances (when one substance
O alone is used), or all or some of them in equal proportions, though
exactness as to the proportions of them is not indispensable, the object
being to get a body for the composition, and ensure dryness. These
ingredients are to be well mixed together by stirring, so as to produce a
dry powder, which can be used like other powder manures, and will be
5 found to preserve the potatoe against disease, and improve the crop, and
also will prove advantageous for dressing and manuring land for other
agricultural purposes.

page_text: Having now particularly described and ascertained the nature and
object of my said Invention, and in what manner the same is to be
performed or carried out in practice, I hereby declare that I claim the
herein-before described Invention of "Improved Composition for Pre-
vention of Potatoe Disease, Applicable also for Dressing and Manuring t
Land for other Agricultural Purposes," as the same is herein described,
it being understood that I do not limit myself to the use of nor do I
claim the constituent substances above mentioned per se, except as used
or combined as herein-before described.
In witness whereof, I, the said John Lott, have hereunto set my
hand and seal, this Twelfth day of May, in the year of our Lord
One thousand eight hundred and seventy-five.
