The experiment is on a nurse 28 years old, who is not at all hysterical. She is a daughter of plain country people, and has been for a long time an attendant in the Zurich Lunatic Asylum, which Forel directs. He thinks her a capable honest person, in no way inclined to deceit. The experiments were as follows: A gummed label was fixed upon her chest on either side; the paper was square. In no case was an irritating gum used. At mid-day Forel suggested that a blister had been put on the left side; and at six o'clock in the evening a moist spot had appeared in that place; the skin was swollen and red around it, and a little inflammation also appeared on the right side, but much less. Forel then did away with the suggestion. On the next day there was a scab on the left side. Forel had not watched the nurse between noon and six o'clock, but had suggested that she could not scratch herself. The other nurses said that the subject could not raise her hand to her chest, but made vain attempts to scratch. Forel repeated the experiment later; he put on the paper at 11:45 a. m. and ordered the formation of blisters in two and one half hours. Little pain was suggested, and the nurse therefore complained but little. At two o'clock Forel looked at the paper on the left side, for which the suggestion had been made, and saw around it a large swelling and reddening of the skin. The paper could with difficulty be removed. A moist surface of epidermis was then visible, exactly square like the paper. There was nothing particular under the paper on the right side. Forel then suggested the disappearance of the pain, inflammation, etc.
