Improvements in the Preparation of Materials to be Used as
Disinfectants, Deodorisers, and Antiseptics, as well as for the
Destruction of Parasites Infesting Man and the Lower Animals
and similar Uses.
I RICHARD VINE TUSON of New Charlton, Kent, Professor of Chemistry, Royal
Veterinary College, Camden Town, London, do hereby declare the nature of my said
invention to be as follows:-
According to a previous invention for which Letters Patent were granted to me
(A.D. 1879-19th March No. 1081) I prepared disinfectants by saturating or partly
saturating with sulphurous acid a solution or solutions of well known salts of zinc,
iron, manganese, aluminum or copper, or a mixture of these.
My present invention consists in saturating or partly saturating with sulphurous
acid a solution of corrosive sublimate or other salt of mercury in water, alcohol, or
other convenient solvent.
I prefer to use corrosive sublimate, but the nitrates and many other salts of mercury
will give similar results.
The solution of corrosive sublimate or other salt of mercury saturated or partly
saturated with sulphurous acid may be used singly or may be mixed with any chloride,
sulphate, nitrate or acetate of zinc, iron, manganese, aluminum, or copper, or a
mixture of these.
1 have obtained a good result by saturating or partly saturating with sulphurous
acid a mixture of chloride of zinc and corrosive sublimate.

I RICHARD VINE TUSON of New Charlton, Kent, Professor of Chemistry, Royal
Veterinary College, Camden Town, London do hereby declare the nature of my
said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
According to a previous invention for which Letters Patent were granted to me
(A.D. 1879, 19th March No. 1081) I prepared disinfectants by saturating or partly
saturating with sulphurous acid a solution or solutions of well known salts of zinc,
iron, manganese, aluminum, or copper or a mixture of these.
My present invention consists in saturating or partly saturating with sulphurous
acid a solution of corrosive sublimate or other salt of mercury in water, alcohol or
other convenient solvent. I prefer to use corrosive sublimate, but the nitrates and
many other salts of mercury will give similar results. The solution of corrosive
sublimate or other salt of mercury saturated or partly saturated with sulphurous acid
may be used singly or may be mixed with any chloride, sulphate, nitrate or acetate of
zinc, iron, manganese aluminum or copper or a mixture of these.
I have obtained a good result by saturating or partly saturating with sulphurous
acid, a mixture of chloride of zinc and corrosive sublimate.
The proportions I prefer to use are 3 lbs. of chloride of zinc and 2 ounces of
corrosive sublimate dissolved in half a gallon of water and then to make up this
solution to one gallon by adding a saturated watery solution of sulphurous acid.
Other proportions may be employed, but these have been found to work well in
practice.
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 :-
The preparation of ingredients and their employment as disinfectants, deodorisers,
and antiseptics; as well as for the destruction of parasites infesting man and the
lower animals, and similar uses, as herein before described.
