PROVISIONAL SPECIFICATION.
Improvements in Baths for Medical Purposes.
I, CAUTLEY DAWSON, of Rawdon, near Leeds, in the County of York, Surgeon,
do hereby declare the nature of this invention to be as follows
--
According to this invention the bath is made of earthenware or other material
which is a non-conductor of electricity. The bath may be of any shape but it
must be divided by a non-conducting partition. The bath is filled with a suitable
conducting liquid such as water or salt water, and the bather places one foot in
each division.
Sometimes I provide a copper plate at the bottom of one compartment and a
zine plate at the bottom of the other compartment and on each of these plates the
bather rests one foot.
Or sometimes I employ an external battery connected with conducting surfaces
one in each compartment and these surfaces are in contact with the conducting
liquid in each compartment in each of which the bather places one foot.

COMPLETE SPECIFICATION.
Improvements in Baths for Medical Purposes.
I, CAUTLEY DAWSON of Rawdon near Leeds, in the County of York, Doctor of
Medicine, 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 :-
According to this invention the bath is made of earthenware or other material
which is a non-conductor of electricity. The bath may be of any shape but it
must be divided by a non-conducting partition or there may be two baths insulated
from each other. The bath is filled with a suitable conducting liquid such as water
or salt water, and the bather places one foot in each division.
Or sometimes I employ an external battery connected with conducting surfaces
one in each compartment and these surfaces are in contact with the conducting liquid
in each compartment in each of which the bather places one foot.
Figure 1 is a plan of the bath.
Fi
Figure 2 is a longitudinal section.
Figure 3 is a transverse section.
The bath is divided into two compartments A and B by the partition C.
In the parts A and B are two metal plates D and E of copper or other conducting
metal which are connected by wires F F to the poles of a battery.
When the plates. D and E are connected to the poles of a battery various currents
can be obtained by the bather viz.
(1) A continuous current.
(2) An interrupted current.
(3) The primary current of a Faradisation coil.
(4) The secondary current of a Faradisation coil, and any combination of the
above.
In short any kind of electricity used in medical therapeutics can be administered
most advantageously by these baths.

page_text: 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 combination of a bath divided into two compartments by a partition of
non-conducting material, or of two baths insulated from each other, a galvanic
battery and connections from the poles of the battery to conducting surfaces in
each compartment of the bath.
