Eye Ointment.

Red oxide of mercury, 12 grains; spermaceti ointment, 1 oz. Mix.

The above prescription was given to me many years ago by the late Dr. Walsh (Stonehenge), and I have found it of great service, both for my own eyes, also those of animals and birds. Wash the eyes carefully with warm water, dry off with a soft silk handkerchief, and apply a little of the ointment. Dr. Walsh informed me that he deemed it excellent for canker in the ear, but of that I have had no experience.
