PROVISIONAL SPECIFICATION.
An Improved Sheep Dip and Antiseptic Dressing and Preservative
for Hides and the like.
I, GEORGE RICHARDSON MORRISON, Chemist, of Richmond House, Richmond
Street, Plaistow, in the County of Essex, do hereby declare the nature of this
invention to be as follows:-
My invention relates to a composition of ingredients forming a sheep dip, which
is also well adapted as an antiseptic dressing and preservative for raw hides, skins,
and the like. The object is to provide a composition which may be used either as
a sulphur or an arsenic dip or dressing, which is not liable to be washed out by rain
but will remain permanently fixed or mordaunted in the fleece, hair, skin, or other
article to which it has been applied.
The composition for a sulphur dip or dressing consists of the following ingredients
combined in suitable proportions. The hyposulphites, sulphites, or sulphides of
organic or inorganic base or origin, and the acid sulphates or free acids, mixed with
water.
For an arsenic dip or dressing to the above ingredients is added a suitable
proportion of arsenite of soda, soda arseniates, or other compounds of arsenic or
antimony.
The action of the acid bases or free acids referred to in either case precipitates
the sulphur (and arsenic if used) in an extremely fine state of sub-division or
nascent condition, and so admits of their penetration well into the fleece, hair, or
hide, and the chemical reaction takes place either in the bath, or during the
dressing, or subsequently.

COMPLETE SPECIFICATION.
An Improved Sheep Dip and Antiseptic Dressing and Preservative
for Hides and the like.
1, GEORGE RICHARDSON MORRISON, Chemist, of Richmond House, Richmond
Street, Plaistow, in the County of Essex, 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 :-
My invention relates to a composition of ingredients forming a sheep or animal
dip and which is also well adapted as an antiseptic dressing and preservative for
hides, skins, and the like either raw or dressed.
My object is the production of a composition which may be used either as a
sulphur or as an arsenic dip or dressing, which is not liable to be washed out by
rain but will remain permanently fixed or mordanted in the fleece, hair, skin, or
other article to which it has been applied.

page_text: If a "sulphur" dip only is required, it is composed of a mixture of one or more
of the inorganic hyposulphites with an acid-sulphate or free acid, dissolved in
water in suitable proportions. The acid may be in the form of an acid sulphate
when sulphuric acid is used, or it may be used in the usual form or it may be
combined with an absorbent, such as kieselguhr.
When a poisonous dip is required, to a "sulphur" dip, composed as above
described, is added a suitable proportion of arsenite of soda or of one or more of
the salts of the metals, mercury, arsenic, tin or antimony or metals of the same
chemical group.
I may vary the proportions of the ingredients above detailed, but as a general rule
the proportions I prefer are (when using pure chemicals) for a dry (i.e., anhydrous)
compound which only requires to be dissolved in water to give the mixture which
I claim as my invention:-
to be dissolved in 1,000 to 1,200 gallons of water; or I may substitute for the
arsenite of soda, chloride of antimony-24 lbs., or chloride of tin-24 lbs., or
chloride of mercury-12 lbs.
If I use impure chemicals such as bye-products the proportions will vary
according to the percentage of the pure chemicals required which exists in such
bye-products.
or
and
Either of the solutions thus prepared is to be employed in the usual manner in
which such sheep or animal dips or preservatives are used and the action is
to produce in or upon the fleece, hide, skin or the like, finely-divided sulphur
metallic sulphides, which result is brought about in the case of live animals by
the slow decomposition of the mixture in the fleece by the natural heat of the
animal itself. The fine sulphur or metallic sulphide adheres most strongly to the
fleece, and is present in the most advantageous form for the destruction of
the parasites as they mature and develop from the eggs.
In the case of hides or skins, the action is brought about by the natural
fermentation, which produces a sufficient amount of heat to bring about the
re-action, or the bath itself may be heated with a view to bringing about the same
result.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
1. The production of a sheep or animal dip composed of the inorganic hypo-
sulphites with an acid or acids, substantially as herein before described.
2. The production of a sheep or animal dip or an antiseptic dressing for skins,
hides and the like, composed of the inorganic hyposulphites with an acid or acids.
and a salt or salts of the metals mercury, arsenic, tin or antimony, substantially as
above described.
3. In the production of a sheep or animal dip or preservative compound, the use
of inorganic byposulphites with an acid or acids and a salt or salts of the metals

page_text: mercury, arsenic, tin or antimony for the purpose of producing in or upon the
fleece, skin or hide a deposit of finely-divided sulphur a metallic sulphide or
sulphides, substantially as hereinbefore described.
