difficulty in finding her way about the room. Her vision without glasses was 3/200. All reading had been for bidden, playing the piano from the notes was not al lowed, and she had been obliged to give up the idea of going to college. The sensitiveness to light was re lieved in a few minutes by focussing the light of the sun upon the upper part of the eyeball when she looked far down, by means of a burning glass (see Chapter XVII). The patient was then seated before a Snellen test card and directed to look away from it, rest her eyes, and then look at the big C. For a fraction of a second her vision was improved, and by frequent demon strations she was made to realize that any effort to see the letters always lowered the vision. By alternately looking away, and then looking back at the letters for a fraction of a second, her vision improved so rapidly that in the course of half an hour it was almost normal for the distance. Then diamond type was given her to read. The attempt to read it at once brought on a severe pain. She was directed to proceed as she had in reading the Snellen test card; and in a few minutes, by alter nately looking away and then looking at the first letter of each word in turn, she became able to read without fatigue, discomfort, or pain. She left the office without her glasses, and was able to see her way without diffi culty. Other patients have been benefited as promptly by this simple method.
