PROVISIONAL SPECIFICATION.
Improvements in Compounds for Washing or Dipping Sheep, Cattle,
and Horses for the Extermination of Insects or Parasites.
We ISAAC SHIMWELL MCDOUGALL and JAMES THOMAS MCDOUGALL both of
10 Mark Lane in the City of London Manufacturing Chemists do hereby declare the
nature of this invention to be as follows:-
Compounds for washing or dipping sheep cattle and horses have been produced from
liquids or their crystals obtained in the distillation of carbonaceous substances and
also from oils or their crystals found existing naturally in the earth. These compounds
have hitherto been in the form of liquids pastes or soaps and supplied in iron or wood
packages being too oily or damp to admit of being packed in paper alone to form a
cleanly parcel for transport and distribution.
Our improvements consist in rendering any of these materials liquids crystals soaps
or dips or any mixture or mixtures of them into a dry or nearly dry or friable
compound or mixture so that when packed in suitable paper a clean parcel is obtained
and further that the resulting compound shall be more mixable in cold water than
when in the solid or unpowdered form.
This accomplish by incorporating any of the materials referred to with any
suitable absorbent or drying material or materials such as for instance calcined
magnesia infusorial earth or sulphur in a finely divided state in such proportions that
a friable compound or powder is produced suitable for washing or dipping sheep
cattle or horses for the extermination of insects or parasites.
Hitherto powders that have been produced for the dipping of sheep and goats.
have been composed of arsenic or other poisonous matter with an alkali and sulphur
and so have been of a highly dangerous character both to the animals and the persons.
applying them so much so that they can hardly be used upon cattle and horses.
without fatal results. By our improvements we produce a powder which whilst
efficient for the extermination of insects or parasites can be applied with perfect.
safety to both the animals and the users.

COMPLETE SPECIFICATION.
Improvements in Compounds for Washing or Dipping Sheep, Cattle,
and Horses for the Extermination of Insects or Parasites.
We ISAAC SHIMWELL MCDOUGALL and JAMES THOMAS MCDOUGALL of 10 Mark
Lane in the City of London Manufacturing Chemists 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:-
Compounds for washing or dipping sheep, cattle, and horses, have been produced
from liquids, or their crystals, obtained in the distillation of carbonaceous substances.
and also from oils, or their crystals, found existing naturally in the earth. These
compounds have hitherto been in the form of liquids pastes or soaps and supplied in
iron or wood packages being too oily or damp to admit of being packed in paper alone.
to form a cleanly parcel for transport and distribution.
Our improvements consist in rendering any of these materials, liquids, crystals,.
soaps, or dips, or any mixture, or mixtures, of them, into a dry, or nearly dry, or
friable, compound, or mixture, so that when packed in suitable paper a clean parcel

water than when in the solid or unpowdered form.
This we accomplish by incorporating any of the materials referre: to with any
suitable absorbent or drying material or materials such as for instance calcined
magnesia, infusorial earth, or sulphur in a finely divided state in such proportions that
a friable compound, or powder, is produced suitable for washing, or dipping, sheep,
cattle or horses, for the extermination of insects, or parasites.
Hitherto powders that have been produced for the dipping of sheep and goats have
been composed of arsenic or other poisonous matter with an alkali and sulphur and
so have been of a highly dangerous character both to the animals and to the persons
applying them so much so that they can hardly be used upon cattle or horses without
fatal results. By our improvements we produce a powder which whilst efficient for
the extermination of insects or parasites can be applied with perfect safety to both
the animals and the users. The following we give as examples of compounds or
mixtures which we find to answer well in practice. The parts being by weight.
