SPECIFICATION.
I WILLIAM HIBBERT of Clarence Street Cheetham Manchester in the County
of Lancaster Manufacturing Chemist do hereby declare the nature of my invention
for "AN IMPROVED MIXTURE OR COMPOUND FOR PREVENTING OR ARRESTING THE
DECOMPOSITION AND PUTREFACTION OF ANIMAL AND VEGETABLE MATTERS " and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of this invention is to preserve animal and vegetable matters from
decay by preventing or arresting fermentation which is the cause of the decom-
position and consequent putrefaction of such matters.
The mixture or preparation which I propose to employ for this purpose is a
solution of the following ingredients namely.
Muriate of Magnesia
Muriate of Soda
Bromide of Magnesium
and Sulphate of Patassium.
The strength of the solution and the proportions of the different ingredients will
depend in a great measure upon the particular animal or vegetable matter (whether
Bolid or liquid) to which it is intended to be applied and also upon the fact whether
such animal or vegetable matter is in a fresh state, or in an incipient or advanced
state of decay, but a solution which I have found to be efficacious for general
preservative purposes and which is sufficiently strong to arrest decay or
decomposition when in an advanced stage may be made as follows. To one gallon
of a solution of muriate of magnesia at a strength of about 50 degrees (Twaddle)
I add about half an ounce of bromide of magnesium I then add about half a pound
of murinte of soda and about three quarters of an ounce of sulphate of potassium.
These ingredients being thoroughly well mixed and incorporated together the
whole is allowed to stand to allow of the settlement of any precipitate that may
be formed and the clear liquor is then drawn off ready for use.
As an example of the use of this mixture, I may state that if a carcase or a
joint of meat in a fresh state be impregnated or brushed over with the solution
and then wrapped in a cloth damped or saturated with the compound it will be
kept fresh and preserved from decay for a very considerable period and that if a
Price 2d1

page_text: carcase or a joint of meat in an incipient or even advanced state of decomposition
were to be dipped in or otherwise impregnated with tho solution or to be enveloped
in a cloth or other material used for packing and damped or saturated in like
manner all decay or decomposition arising from fermentation would be at once
arrested and in a very short time (say a few minutes) all disagreeable odour or
taste would be removed, and no unpleasant flavor whatever would be imparted to
the meat. Or the solution if mixed with the water in which a joint is cooked
would remove all traces of taint.
The various antiseptic purposes for which this solution may be applied are very
numerous and the modes of its application are consequently capable of great
variation and will as before stated depend upon the particular nature and condition
of the animal or vegetable matter to which it is to be applied but however the
proportions and strength of the solution may be varied the ingredients will remain
the same.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is the mixture or compound for preventing or arresting the decomposition
and putrefaction of animal and vegetable matters formed by the combination of
muriate of magnesia, muriate of soda, bromide of magnesium and sulphate of
potassium as herein before more particularly set forth.
