I, JOHN THOMSON, of 70* Grosvenor Street, W., in the County of Middlesex,
Photographer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the art of combining biniodide of
mercury with soap for the sake of increasing the purifying properties thereof in
the laundry, the sick room, and the hospital, said soap being prepared substantially
as described in my specification No. 9591 of 1886, although I may alter the
quantity of materials used indefinitely.
In the specification of my patent No. 9591, July 24th 1886, granted to me for
my invention of an improved antiseptic soap, I have specified certain proportions
in which the biniodide is to be incorporated with ordinary soap to endow it with
the desired antiseptic properties. These proportions are specified as ranging from
one-ten thousandth up to one hundredth part.
Now since the date of the above mentioned patent I have found that the
valuable sanitary properties of biniodide of mercury are not confined within the
proportions specified above, as I thought at the date of my said patent that they
were, but that they extend to every practicable proportion in which the biniodide
can be incorporated with soap.
Now, therefore, according to my present invention 1 do not limit myself to the
proportions set out in my former specification, nor do I confine myself solely to
the uses for it therein claimed but I may use as high a proportion as one of
biniodide of mercury to five of soap. A soap charged with this or smaller pro-
portion of biniodide is a valuable remedy in skin diseases, and the proportion may
be increased or diminished as the virulence or stubbornness of the disease, or
whatever may be the exigencies of the purpose to which the soap is applied, may
demand.
My invention does not confine me to any particular method of combining the
biniodide with the soap, inasmuch as I may use any which may be suitable; but
I prefer to use the process fully described in my former specification.

page_text: I, JOHN THOMSON, of 70 Grosvenor Street, W., in the County of Middlesex,
Photographer, 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 :-
My invention relates to improvements in the art of combining biniodide of
mercury with soap for the sake of increasing the purifying properties thereof in
the laundry, the sick room, and the hospital, said soap being prepared in respect
of the methods of incorporating the biniodide with the soap mass substantially as
described in my specification No. 9591 of 1886, the present invention relating to
the relative proportions in which the biniodide is combined with the soap.
In the specification of my patent, No. 9591, July 24th 1886, granted to me
for my invention of an improved antiseptic soap I have specified certain propor-
tions in which the biniodide is to be incorporated with ordinary soap to endow it
with the desired antiseptic properties. These proportions are specified as ranging
from one ten thousandth up to one hundredth part of the biniodide to one part
of soap.
Now since the date of the above mentioned patent I have discovered that the
valuable antiseptic or sanitary properties of biniodide of mercury are not confined
within the proportions specified above, as I thought at the date of my said patent
that they were; but that they extend to every practicable proportion in which
the biniodide can be incorporated with soap.
Now, therefore, according to my present invention I do not limit myself to the
proportions set out in my former specification, nor do I confine myself solely to
the uses therein claimed for 1 may use as high a proportion as one of biniodide of
mercury to five of soap. A soap charged with this or smaller proportion of
biniodide is a valuable remedy in skin diseases and may be used with advantage
for the cleansing of infected body or bed linen, the hands after contact with cases
of contagious diseases, or the floors and walls of fever wards. The said propor-
tion of five to one may be increased or diminished, as the virulence, or stubborn-
ness of the disease, or whatever may be the exigencies of the purpose to which
the soap is applied may demand.
My invention does not confine me to any particular method of combining the
biniodide with the soap mass, inasmuch as I may use any which may be suitable;
but I prefer to use the process fully described in my former specification, nor do
I confine myself to any particular kind of soap, inasmuch as the selection of the
soap may be decided according to the special requirements of any particular case
but other things being equal I make use of any of the soaps in general use.
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. An improved mercurial soap consisting of biniodide of mercury incorporated

page_text: with the soap mass in any proportions less than one ten thousandth part of the
biniodide to one of soap, the exact proportion being regulated according to the
greater or less strength of the impurities to be cleansed away, substantially as
described.
2. An improved mercurial soap consisting of biniodide of mercury incorporated
with the soap mass in any proportions more than one hundredth part of the
biniodide to one of soap, the exact proportion being regulated according to the
greater or less virulence of the impurities to be cleansed away, substantially as
described.
