page_text: I, AUGUSTUS COLLINGRIDGE of 87 New Oxford Street, London, Operative. Chemist,
do hereby declare the nature of this invention to be as follows:-
This invention is designed to advance the employment of ordinary salt for medicinal.
and curative purposes, and for hygienic bathing, by combining it with galvanism and
with other remedial agents for the removal and mitigation of disease, and also to
increase its utility as an article of food.
Firstly to produce a galvanic medicated salt for external application and similar
purposes, I propose to thoroughly incorporate magnetised iron with the salt, and to
effect this I take a certain quantity of soft iron, that is of iron free from carbon, in
any form such as wire, bar, scrap, filings or oxide. This iron I first magnetise by
the process of induction, that is by passing one or more powerful currents of electricity
from a galvanic battery through the metal. I then steep it in a strong or saturated
solution of, brine. Through this mixture I then pass strong currents of carbonic acid
gas, generated in the usual manner, too well known to require description here. This
serves to accelerate the process of oxidation necessary to incorporate completely the
brine with the metal. This operation may be still further hastened by repeating the
galvanic current.
The liquid is then strained off through a coarse sieve and dried into crystals in the
usual way.
Secondly for the production of an edible or table salt with valuable medicinal
properties, I proceed as above, with the exception of rendering the brine much weaker
in its metallic properties, and after subjecting the mass to the final galvanic currents,
I introduce a small percentage, say from five to ten per cent. of alkaline neutral salts,
and of phosphates tending to counteract acidity in the stomach, and thereby assist in
the assimilation and digestion of food.
I am aware that salt has already been impregnated with iron by means of forming
a brine into which fine wire is introduced, after the mode of the most approved formula
for making "Vinum Ferri" in the Pharmacopoeia; but the employment of Galvanism
and Carbonic acid gas in addition is .novel and beneficial and of great practica]
advantage in expediting the process, as the method I have herein described shortens
the period required for impregnation by about ninety-five per cent.

I; AUGUSTUS COLLINGRIDGE, of 87 New Oxford Street, London, Operative Chemist,
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 is designed to advance the employment of ordinary salt for medicinal
preventive and curative purposes and for hygienic bathing by combining it with
galvanism and with other remedial agents for the removal and mitigation of disease,
and also to increase its utility as an article of food.
I propose, Firstly to produce a galvanic medicated Salt for external application and
similar purposes, to thoroughly incorporate magnetised iron, with the salt, and to effect
this I take a certain quantity of soft iron, that is of iron free from carbon, in any form.
such as wire, bar, scrap filings of oxide. This iron I first magnetise by the process of
induction, that is by passing one or more powerful currents of electricity from a
galvanic battery, through the metal. I then steep it in a strong or saturated solution
of brine. Through this mixture I then pass strong currents of carbonic acid gas,
generated in the usual manner, too well known to require description here. This
serves to accelerate the process of oxidation necessary to incorporate completely the
brine with the metal. This operation may be still further hastened by repeating the
galvanic current:
The liquid is then strained off through a coarse seive and dried into crystals in the
usual way.
Secondly, for the production of an edible or table salt with valuable medicinal
properties, I proceed as above, with the exception of rendering the brine much
weaker in its metallic properties, and after subjecting the mass to the. final galvanic
currents, I introduce a small percentage, say from five to ten per cent. of Alkaline
neutral salts, and of phosphates tending to counteract acidity in the stomach, and
thereby assist in the assimilation and digestion of food. In addition to the neutral
Salts and phosphates I use sometimes a small quantity of Citric acid or may substitute
Citric acid for the Carbonic acid gas if preferred.
I am aware that Salt has already been impregnated with iron by means of forming
, a brine into which fine wire is introduced, after the mode of the most approved formula
for making "Vinum Ferri" in the Pharmacoepia; but the employment of Galvanism and
Carbonic acid gas in addition is novel and beneficial and of great practical advantage
in expediting the process, as the method I have herein described shortens the period
required for impregnation by about 95
per cent.

page_text: 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 :
1. In a medicated salt for external application. The combination with salt of
galvanised iron and carbonic acid gas in the manner herein described and set forth.
2. In an edible or table salt. The combination of salt with galvanised iron, carbonic
acid gas, alkaline neutral salts and phosphates and citric acid, or of the foregoing
substances, omitting the carbonic acid gas if preférred, as herein described and set
forth.
