Complete Specification Accepted, 9th Nov., 1888
I, JOHN THOMSON, of 70ª 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 the production of an improved ointment which is especially
adapted for the treatment of skin diseases; and consists in the combination with
biniodide of mercury of a suitable vehicle by means of which the curative properties
of the biniodide may be brought to bear upon diseases of the skin, by way of
applying an ointment containing the desiderated percentage of the said biniodide to the
affected part.
In carrying my invention into effect, I mix the biniodide with lenoline or other
suitable vehicle. I instance lenoline as one among many other vehicles which
may be mentioned as typical in respect of suitability for the purpose to which it is
to be put.
The proportions in which the biniodide is to be mixed with the lenoline varies, of
course, according to the virulence of the disease to be treated; but I am of opinion
that the limits of curative efficiency are comprised between 10% and 600 %, calculated
upon the weight of the vehicle.
Datad this 16th day of December 1887

An Improved Ointment.
1, JOHN THOMSON, of 70ª, 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 the production of an improved antiseptic pomade or ointment
which is especially adapted for the treatment of skin diseases, for use during periods
of desquamation, and as an antiseptic lubricant in obstetric cases. It consists in the
combination with mercurial iodides, especially the biniodide, of a suitable vehicle by
means of which the curative properties of the mercurial salt may be brought to bear
upon abnormal conditions and diseases of the skin, by way of applying an ointment
or pomade containing the desiderated percentage of the said salt.
In carrying my invention into effect, I mix the salt with lanoline, or other suitable
vehicle. I instance lanoline as one amongst many other vehicles which may be men-
tioned, as typical in respect of suitability for the purpose to which it is to be put,
but I may use any emollient, e.g., vasaline lard as commonly employed in preparing
ointments.
The proportions in which the salt is to be mixed with the emollient vary, of course,
according to the virulence of the disease to be treated. I do not confine myself to any
definite proportions, but I find that in skin diseases 1 to 3% may be employed ;-
whilst when used for obstetric and other such purposes 1 part of biniodide in solution
to 2,000 or 4,000 of emollient may be with advantage used.
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 improved ointment consisting of the above mentioned ingredients substantially
as set forth.
