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 to be as follows :— 5 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 10 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. 15 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 20 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. 25 The suction end of this pump we connect to the apparatus, in which vapour is generated. r Price 8d.]
