page_text: I, PAUL STERN, of Dorotheenkirche 3, Breslau, in the German Empire, Apothe-
cary, do hereby declare the nature of this invention to be as follows:-
This invention relates to the preparation of corrosive sublimate for sale in a
convenient and easily soluble form.
It has hitherto commonly been sold in the form of pellets mixed with common
salt, these pellets being wrapped in black or other paper and distinctively marked,
and then placed in a glass tube or bottle. In this form several inconveniences were
presented, the pellets taking a considerable time to completely dissolve in water,
especially in cold water, and frequently crumbling and melting during transport,
and especially when carried in the pocket.
In carrying this invention into effect small leaves of filtering paper or other
similar or suitable material are saturated with a solution, preferably coloured, of
the corrosive sublimate and are then dried. Each leaf contains one gramme of
the sublimate or any other convenient quantity. If one of these leaves be placed
in water the contained sublimate is immediately dissolved owing to the large
surface presented to the liquid. The colouring matter, when employed, is also
dissolved and gives a colouration to the liquid so as to prevent accidents.
The saturated and dried leaves may be packed within suitable and distinctive
coverings or envelopes, and may thus be easily carried and transported.

Agents for the Applicant,
I, PAUL STERN, of Dorotheenkirche 3, Breslau, in the German Empire, Apothe-
cary, 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 corrosive sublimate for sale in a

pellets or tablets these tablets being wrapped in black or other paper and dis-

.
In carrying this invention into effect small leaves of filtering paper or other
similar or suitable material are saturated with a solution, preferably coloured, of
the corrosive sublimate and are then dried. Each leaf contains a certain fixed
quantity of the sublimate, as, for example, one gramme. If one of these leaves
be placed in water the contained sublimate is immediately dissolved owing to the
large surface presented to the liquid. The colouring matter when employed, is
also dissolved and gives a colouration to the liquid so as to prevent accidents.
The accompanying drawing illustrates a square or other shaped piece of paper
or suitable absorbent material which is saturated with a solution of corrosive
sublimate.
a indicates the piece of paper which may, if desired, be sub-divided to any
desired extent by means of the lines b and c. Thus, if the whole sheet a contains
one gramme of the sublimate, half a gramme may be obtained when required by
tearing the sheet in half, or a quarter or three quarters of a gramme may be
separated. The lines may be perforated to assist division.
Any suitable distinctive marking may be applied to the squares, either in the
nature of a caution or otherwise, and, as before explained, the squares may have
a colouring matter incorporated with them so that the resulting solution is dis-
tinctively coloured.
The squares may be placed in black envelopes or be otherwise made up in dis-
tinctive coverings, and may thus be easily carried and transported.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. A square or sheet of filtering paper or other suitable material which is
saturated with a solution of corrosive sublimate, substantially as and for the
purpose herein before described.
2. A square or sheet of filtering paper or other suitable material which is
saturated with a solution of corrosive sublimate and is divided or sub-divided by
perforated or other lines substantially as hereinbefore described and as illustrated
by the accompanying drawings.
