TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
NEWINGTON, of Ticehurst, in the County of Sussex, Member of the Royal
College of Physicians, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Samuel Newington, Her special licence that I, the said Samuel
Newington, my executors, administrators, and assigns, or such others as I,
the said Samuel Newington, 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 "AN
IMPROVED COMPOUND FOR DESTROYING INSECTS AND PREVENTING AND CHECKING
BLIGHT IN PLANTS," upon the condition (amongst others) that I, the said
Samuel Newington, my executors or administrators, by an instrument in
writing under my, or their, or one of their bands and seals, should par-
ticularly 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 1, the said Samuel Newington, do hereby declare

page_text: the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object an improved compound for destroying
insects and preventing and checking blight in plants. For this purpose I
employ a compound consisting of ground tobacco, sulphur, aud assafoetida in
the proportions by preference of,-
Ground tobacco
Sulphur
Assafoetida
75 parts,
25
"
5
"
This compound is, when required for use, diluted with fine dust or sand, and
in this state it is applied to the surface from which the blight or insects are to
be removed, or to surfaces requiring protection from their ravages, or the
compound may be mixed with water and so applied.
And in order that my said Invention may be most fully understood and
readily carried into effect I will proceed to describe the manner in which it
is preferred to prepare and apply the improved compound.
I take tobacco and reduce it to as fine a powder as possible in a snuff mill
or similar mill, I then add to it finely powdered sulphur and assafoetida in the
proportions above stated and thoroughly mix the materials, for which purpose
it is convenient to employ a barrel furnished with axes on which it is capable
of being rotated; the materials are enclosed in the barrel, which is turned
until a complete mixture is effected; the material may, however, be mixed by
hand labour, or other mechanism may be employed. The compound is now
ready for the market; it requires, however, to render it suitable for use the
addition of another ingredient, namely, fine dust or sand; the most suitable
dust for the purpose is powdered lime in a nearly, but not perfectly, slaked
state, and I add to 112 lbs. of the compound in its marketable form about
47 lbs. of lime dust and 233 lbs. of very fine siliceous sand. The mixture is
conveniently applied by means of a well-known apparatus, which has hereto-
fore been employed in applying sulphur to plants, and which consists of a
small rotary fan driven by hand or otherwise, and the powder is supplied by a
hopper into the current of air coming from the fan, and is carried by it against
the plants to be treated. The powder is best applied when there is no wind,
and whilst the dew is still on the plants; for hops I find about one hundred-
weight to the acre to be a suitable quantity; or in place of operating in this
way the marketable compound may be combined with water, say, in the pro-
portion of three or four pounds of the compound in its marketable form to

page_text: the hundred gallons of water, the mixture is conveniently distributed over the
plants by means of a pumping engine and a rose.
What I claim is the improved compound in its marketable form obtained
by combining ground tobacco, sulphur, and assafoetida, as described.
I also claim the improved compound in the form in which it is applicable
to the plants, and which is obtained by further combining the compound in its
marketable form with fine dust, or sand or with water, as described.
In witness whereof, I, the said Samuel Newington, have hereunto set
my hand and seal, this Thirty-first day of August, in the year of our
Lord One thousand eight hundred and sixty-seven.
SAMUEL NEWINGTON. (L.s.)
