PROVISIONAL SPECIFICATION.
Improvements in Means for Protecting Seeds from Parasites, Insects,
Birds, and Vermin.
I, EVAN GRIFFITHS HUGHES, of Victoria Street, Manchester, Chemist, do
hereby declare the nature of this invention to be as follows:-
The improvements relate to, and have for object, a means for protecting seeds
from the attack of parasites, insects, vermin, and birds; improving their condition,
and greatly increasing their chances of growth, as well as exciting them to sprout
much sooner.
To accomplish this, and to effect my improvements, I provide a convenient
quantity of one of the salts of lead, by preference, acetate of lead-which I mix
with, or produce in combination with pyroligneous tar, or pyroligneous acid; and,
to this mixture or combination, I then add a suitable quantity of water to make a
solution.
Seeds which are treated with or immersed in this solution, prior to being placed
in the ground, are protected from the attacks of parasites, insects, vermin and
birds.
I would have it understood that I do not confine myself to the employment of
the particular salt of lead specified, as other salts of that base may be used in
combination with the pyroligneous tar or pyroligneous acid, and with water as a
vehicle; and variations in the quantities and proportions of the different ingredients,
may be made without departing from the peculiar character of the invention.
Dated this 4th day of March 1893.

COMPLETE SPECIFICATION.
Improvements in Means for Protecting Seeds from Parasites, Insects,
Birds, and Vermin.
I, EVAN GRIFFITHS HUGHES, of Victoria Street, Manchester, Chemist, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The improvements relate to, and have for object, a means for protecting seeds
from the attack of parasites, insects, vermin and birds; improving their condition,
and greatly increasing their chances of growth, as well as exciting them to sprout
much sooner.
To accomplish this, and to effect my improvements, I provide a convenient
quantity of one of the salts of lead-by preference, acetate of lead-which I mix
with, or produce in combination with pyroligneous tar, or pyroligneous acid; and
to this mixture, or combination, I then add a suitable quantity of water to make a
solution.
I find it convenient to obtain the pyroligneous tar or acid from the distillation of
wood, and to employ the crude product arising therefrom, for the purpose described;
but the combination may be made from the more purified chemical substances.

page_text: Practical and effective proportions for the mixture of the substances forming the
composition described may consist as follows:-
Acetate of lead:
-
Crude pyroligneous tar product above alluded to:
Water:
1 lb.
-
2 ozs.
4 gallons.
But an effective result may also be obtained with considerable variation from
these proportions.
Seeds which are treated with or immersed in this solution, prior to being placed
in the ground, are protected from the attacks of parasites, insects, vermin and
birds.
I would have it understood that I do not confine myself to the employment
of the particular salt of lead specified, as other salts of that base may be used in
combination with the pyroligneous tar or pyroligneous acid, and with water as a
vehicle. It will also be obvious that a combination of such salts may be employed,
and that variations in the quantities and proportions of the different ingredients,
also in the manner of treatment with the solution, may be made without departing
from the peculiar character of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
For the protection of seeds from the attacks of parasites, insects, birds and
vermin, and assisting the germination thereof, a solution or mixture composed of
one or more of the salts of lead, and pyroligneous tar or pyroligneous acid, together
with water as a vehicle, in manner substantially as herein set forth.
Dated this 27th day of November 1893.
