WILLIAM DALE, boot-maker, of 14, Clarence Gardens, Regent's Park, visited me in July, 1837. He stated, that with his right eye, for the last year, he could only discern light from darkness; and that for several months before he was much troubled by clouds and spots floating before his eyes. The evening gaslight produced a continued flashing of light from his eye. The light looked as if surrounded by all the colours of the rainbow. He first went to an Ophthalmic Hospital, where he was blistered on the temple and salivated. Nux vomica produced such an effect upon him that all his limbs were involuntarily twitched, so as to alarm them exceedingly. He then left, and went to another institution for three months; and at length was told that the optic nerve was injured, so as to render a restoration of vision impossible. The left eye, when looked into, had a dark green, muddy hue, and the pupil was exceedingly dilated and immoveable. He was unable to distinguish an object placed before his eyes; yet he states that he could distinguish light from darkness. When he applied to me I had the compound embrocation of pimento applied occasionally to the forehead and temples, by means of a friction sponge. During the first month he was able to discern objects and colours. The pupil acted under the impression of light almost equal to the good eye. It was not until this application had been used for a year that the patient was enabled to read with the eye. I saw the patient this day (the 25th of Jan. 1843). The eye, upon examination, appeared to be in a healthy state. The sight was not so good as when he left me, and after he left off the applications, but this he attributes to the circumstance of his general health not being good, owing to his having suffered from intermittent fever. * * * * *
