without any perceptible effect. After ten days I began to give her tonics instead, and although she took the elixir cinchona with dilute hydrochloric acid, tincture of nux vomica, quinine, iron oxid of zinc, and finally stimulants, there was no improvement and the patient said she remained in total darkness. This tonic course was continued up to the twenty-ninth, and had been followed out thoroughly for two full weeks without effect. During the nearly four weeks treatment the patient said that when the eyes were shut she could discern the position of the lighted lamp, but when the eyes were open she could not see the lamp or the slightest object, or even tell daylight from darkness. At various intervals during this time her pastor visited her and offered her his most heartfelt sympathy. Her friends were becoming exceedingly anxious least the sight would never return, although I could assure them that there was not the least danger of permanent blindness. I became satisfied at this time that medication was not going to dispel this peculiar attack of hysteria and that it would need something besides medicine to produce such an impression upon her mind that she could overcome it, so I told her that I was going to do something the next day that would surely make her see before night, and that she should be of good cheer for her sight would return very soon. The next morning I went down about nine o’clock armed with my ophthalmoscope, my case of trial glasses and my Hearteloup’s artificial leech. The patient seemed to be quite confident that she would soon see, and was very hopeful as to the result of what was to be done. I looked into the eyes with my ophthalmoscope, and then applied the cylinder of the artificial leech to the temples without scarifying and used considerable traction, first on one side and then on the other, having previously told her not to open the eyes until I told her to do so. In about half an hour I told her to open the eyes gradually so as not to let the light in too suddenly and then tell me what she could see. The instant she opened them she said I can see the light and the position of the window. I then told her to close the eyes again and I reapplied the cylinder and commenced the suction as before. By this time the temples had become red and so sensitive that she now complained of some pain when the cylinder was reapplied. After twenty minutes she was told to open the eyes again and she said she could see objects about the room distinctly. She was then tried with large letters but she said she could not see to read them, but could see the black objects. Told her glasses would help her and placed a No. 72 convex spherical glass before the eyes when she could see Jaeger No. 20, then told her she needed other glasses and replaced the No. 72. She now saw to read No. 16. I continued taking off and putting on this same No. 72, with good effect and whenever she came to a standstill in reading reapplied the cylinder
