page_text: LETTERS PATENT to Johann Zacherl, of Vienna, and of 3, Bury Court,
in the City of London, for the Invention of "AN IMPROVED TINCTURE OR
LIQUID PREPARATION FOR DESTROYING INSECTS."
Sealed the 5th July 1864, and dated the 27th January 1864.
PROVISIONAL SPECIFICATION left by the said Johann Zacherl at
the Office of the Commissioners of Patents, with his Petition, on the
27th January 1864.
I, JOHANN ZACHERL, of Vienna, and of 3, Bury Court, in the City of London,
do hereby declare the nature of my Invention for "AN IMPROVED TINCTURE
OR LIQUID PREPARATION FOR DESTROYING INSECTS," to be as follows:-
The tincture or liquid preparation for destroying insects consists of the
following ingredients, viz., about 3 lbs. of Zacherl's Persian insect powder,
made from the Caucasian pyretheum roseum, lb. of insect powder made
from the white pyretheum of Dalmatia, 1 lb. of quassia wood, 1 lb. of
cayenne pepper, lb. of tobacco, lb. of treacle, and lb. of aphne meyereum.
These ingredients are well mixed together & distilled with about 20 lbs. of
mythilated spirits of wine. After distillation the liquid is drawn off, filtered,
& put into bottles, or instead of a liquid or tincture the preparation may be
made and used as a "paper" for destroying insects. For this purpose I take
about 8 lbs. of the pyretheum roseum powder, 2 lbs. of the Dalmatia insect
powder, and 10 lbs. of quassia wood. These ingredients are boiled in about

page_text: 60 lbs. of water until it is reduced to about one half. Stout unsized paper is
then thoroughly saturated with the liquid, and afterwards drained, I then
prepare a mixture of treacle, honey, glycerine, and wood black, and use
this mixture as a printing ink to print on the prepared paper any required
design.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Johann Zacherl in the Great Seal Patent Office on
the 5th July 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHANN
ZACHERL, of Vienna, and of 3, Bury Court, in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Twenty-seventh day of January, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Johann Zacherl, Her special licence that I, the said Johann Zacherl,
my executors, administrators, and assigns, or such others as I, the said
Johann Zacherl, 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 "DESTROYING THE LIFE OF INSECTS,"
upon the condition (amongst others) that I, the said Johann Zacherl, my
executors or administrators, 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.
NOW KNOW YE, that I, the said Johann Zacherl, do hereby declare
the nature of my 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:-
The tincture or liquid preparation for destroying insects consists of the
following ingredients, in about the proportions named, viz., about 3 lbs. of
Zacherl's Persian insect powder, lb. of insect powder made from the white

page_text: pyretheum of Dalmatia, 1 lb. of quassia wood, 1 lb. of Spanish or cayenne
pepper, lb. tobacco, lb. treacle, & lb. of daphne mercereum. These
ingredients are well mixed together, & distilled with about 20 lbs. mythilated
spirits of wine. After distillation the liquid is drawn off, filtered, & put into
bottles. Or instead of a liquid or tincture the preparation may be made &
applied as a "paper" for destroying insects. For this purpose I take about
8 lbs. of the Zacherl's pyretheum roseum powder, 2 lbs. of the Dalmatia
insect powder from the white pyretheum, & 10 lbs. of quassia wood. These
ingredients are boiled in about 60 lbs. of water until it is reduced to about
one half. Stout unsized paper is then thoroughly saturated with the liquid
and afterwards drained. I then prepare a mixture of honey, treacle, glycerine,
& wood black, & use this mixture as a printing ink to print on the prepared
paper any required design.
Having now fully described the nature of my Invention, and the
manner of carrying it into operation, what I claim to be protected by Letters
Patent is the within described preparations or combinations of ingredients for
destroying insects.
In witness whereof, I, have hereunto set my hand and seal, this
Twenty-first day of June, 1864.
