It is well to begin with small doses of the arsenic in form of Fowler’s solution. Two drops may be given thrice daily, in some bitter infusion, to a child between one and two years of age, and gradually increased to four drops. Seldom is it requisite to further increase the dose. Arsenic appears to exercise a marked control over the febrile symptoms of this disease. As the herpetic eruption diminishes, the child ceases to shun the light, and as the rash fades the pustule on the eye heals. The benefit of fresh air in the more obstinate forms of the disease is well known; but it is often difficult to convince parents that exercise in the fresh air will benefit the child. They imagine that it is rather hurtful than otherwise, because the intolerance of light is then a distressing symptom, proper means not having been taken to shade the eyes. A ready method is to place over each eye a pad of cotton wool, and over the pads a bandage, which should encircle the head, and tie on the occiput. The pads should be frequently renewed and the eyelids washed with warm water. In a future paper I hope to bring forward additional facts on the subject, and conclude by giving the history of a number of cases.
