or Weak Condition.
We FREDERICK HARRISON GLEW, Assistant, and THOMAS GREENISH, Pharmaceutical
Chemist, trading as Godfrey & Cooke, both of 30 Conduit Street, Bond Street in
the County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
:-
The few direct methods now adopted of treating the eye and its surroundings when
in a diseased condition, are unsatisfactory, partly by reason of the extreme sensitiveness
of the eye itself, and partly also from the different physical conditions of the several
parts of the eye. In some cases, external applications (drops, lotions, and ointment)
now being used, benefit the eyelids, whilst they irritate the eye itself, and a great
want has been felt for a means of treating the eye as a whole, less open to these
objections.
Now the object of this invention is to supply this long felt want, and the invention
consists in applying the remedial agent to the eye in the form of vapour, or in an
extremely minute state of subdivision.
The remedial agent that we use may be of any suitable kind, but we prefer to
employ the smoke-like vapour of nascent chloride of ammonium in a perfectly neutral
condition, such vapour, from the nature of its constitution, being highly suitable for
the purpose.
This vapour we prefer to produce by means of the apparatus for which we have
already obtained Letters Patent dated 20 December 1886, No. 16713, as in that
apparatus we obtain a perfectly neutral vapour.
In carrying out this invention, we employ a cup of a shape to fit over the eye, and
made of glass or other suitable material. This cup is formed with a hollow stem, to
which is attached an india rubber or other suitable air pump.
The suction end of this pump we connect to the apparatus, in which vapour is
generated.

page_text: In order to ensure the vapour being perfectly neutral, we place in the eye cup, a
piece of damp sponge or other suitable damp porous material. This piece of sponge
also has the effect of diffusing the vapour, thus preventing a direct stream of vapour
impinging on the eye.
When using the properly charged apparatus, the cup is placed over or close to the
open eye, and the bulb of the pump is quickly but gently pressed. By this means,
the vapour will be gradually deposited on the mucous surface of the eye, and be
absorbed thereby, without the least irritation or inconvenience.

An Improved Mode of Treating the Eye when in an Unhealthy
or Weak Condition.
We FREDERICK HARRISON GLEW, Assistant, and THOMAS GREENISH Pharmaceutical
Chemist, trading as Godfrey & Cooke, both of 30 Conduit Street, Bond Street, in the
County of Middlesex, 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 :-
The few direct methods now adopted of treating the eye and its surroundings,
when in a diseased condition, are unsatisfactory, partly by reason of the extreme
sensitiveness of the eye itself, and partly also from the different physical conditions
of the several parts of the eye. In some cases, external applications (drops, lotions,
and ointment) now being used, benefit the eyelids, whilst they irritate the eye itself,
and a great want has been felt for a means of treating the eye, as a whole, less open to
these objections.
Now the object of this invention is to supply this long-felt want, and the invention
consists in applying the remedial agent to the eye in the form of vapour, or in an
extremely minute state of subdivision.
The remedial agent that we use may be of any suitable kind, but we prefer to
employ the smoke-like vapour of nascent chloride of ammonium in a perfectly
neutral condition, such vapour, from the nature of its constitution, being highly
suitable for the purpose.
This vapour we prefer to produce by means of the apparatus for which we have
already obtained Letters Patent dated 20th December 1886, No. 16713, as in tha
apparatus we obtain a perfectly neutral vapour.
In carrying out this invention, we employ a cup of a shape to fit over the eye, and
made of glass or other suitable material. This cup is formed with a hollow stem, to
which is attached an india rubber or other suitable air pump.
The suction end of this pump we may connect to apparatus in which a medicated
vapour is generated.
In order to ensure the vapour being perfectly neutral, we place, in the eye.cup,
a piece of damp sponge or other suitable damp porous material. This piece of
sponge also has the effect of diffusing the vapour, thus preventing a direct stream
of vapour impinging on the eye.
When using the properly charged apparatus, the cup is placed over or close to
the open eye, and the bulb of the pump is quickly, but gently pressed. By this
means, the vapour will be gradually deposited on the mucous surface of the eye,
and be absorbed thereby without the least irritation or inconvenience.
In the accompanying drawing, Fig. 1 shows the arrangement of the eye apparatus,
and Fig. 2 the mode of applying it.

page_text: A is the eye cup, containing a piece of sponge, and provided with a hollow stem A',
to which the tube B¹ of the air pump B is attached. The other tube B' of the pump
is connected to the suction pipe of the chloride of ammonium apparatus C, or to any
other suitable apparatus for producing a medicated vapour.
In using some remedial agents, we may dispense with the use of a separate
generating apparatus; thus, for example, when the medicament to be used is sufficiently
volatile, such as ether, chloroform, prussic acid, camphor, we may add the volatile
agent to the sponge direct.
When used in this manner, the air is passed through or over the volatile agents by
means of the pump, and thereby becomes charged with these vapors.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. The mode of treating the eye, when in an unhealthy or weak condition, by means
of medicated vapour as set forth.
the
2. The means as herein shown and described, for applying a medicated vapour to
eye, and consisting of an eye cup having a hollow stem, in combination with an
air pump.
3. The combination of the parts A and B and their accessories, with an inhaler in
which the medicated vapour is produced, as described.
