PROVISIONAL SPECIFICATION.
A Specific for the Relief and Cure of Indigestion.
I JAMES PHILIP JEFFCOCK of 3 Porchester Place, London, W., Gentleman
do hereby declare the nature of this invention to be as follows:-
This invention relates to the preparation of a specific for the relief and cure of
indigestion, of which the active ingredient is carbonate of bismuth, which is in the
form of an insoluble powder so that it not only does not dissolve in water but is of
such specific gravity that it does not remain in suspension but immediately falls to
the bottom even though the liquid be stirred so that its administration is troublesome
and involves the mixing with the dose of successive quantities of liquid in order that
none of the dose may be left unconsumed.
My invention has for its object to cause this powder to remain in suspension in
the liquid whilst being swallowed so that the entire dose may be taken without
imbibing an undue quantity of liquid, and to this end it consists in preparing the
specific in the form of two powders to be kept separate until required for use,
these powders containing the ingredients in equivalent proportions by which a
vigorous effervessence is produced when mixed together in water, the agitation thus
produced maintaining the active ingredient above mentioned in a state of
suspension throughout the water until the effervessence subsides, thus affording
ample time for the adminstration of the medicine before precipitation can take
place.
The preferred composition of the powders is as follows
COMPLETE SPECIFICATION.
A Specific for the Relief and Cure of Indigestion.
I, JAMES PHILIP JEFFCOCK, of 3, Porchester Place, London, W. Gentleman,
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:-
This invention relates to the preparation of a specific for the relief and cure of
indigestion.

page_text: The active ingredient of this specific is carbonate of bismuth which is insoluble
in water and of such specific gravity that it cannot be kept in suspension by stirring
but immediately falls to the bottom so that the medicina! administration of this drug
is troublesome and necessitates the admixture with the dose of successive quantities
of water in order that the whole of the dose may be taken.
My invention has for its object to cause this powder to remain in suspension
long enough and in a sufficiently small quantity of water to permit of the entire
dose being swallowed at one draught. With this object, the invention consists in
the combination, with the specific, of ingredients in equivalent proportions whereby
a vigorous effervescence will be produced when the ingredients are mixed with
water, so that the agitation produced by the effervescence shall maintain the
whole of the carbonate of bismuth in suspension in the water long enough to
afford ample time for the administration of the medicine before precipitation can
take place.
The ingredients by which the effervescence is produced are prepared in the form
of powders which are to be kept separate until required for use in the same way as
seidlitz powders are prepared, the bismuth carbonate being mixed with one of the
powders of which the composition is preferably as follows:-
The bicarbonate of soda and citric acid, are given merely by way of example,
since equivalent ingredients commonly used in pharmacy whose union in solution
gives rise to brisk effervescence, may be substituted as will be readily understood.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The combination, with carbonate of bismuth, of ingredients in the form of
separate powders whereby a vigorous effervescence will be set up on solution in water,
substantially in the manner and for the purpose specified.
