“Miss A. was a bright, intelligent German girl, twenty-six years of age, free from any hysterical or nervous symptoms. She was the subject of obstinate constipation; her movements seldom occurred without medicine, and she often went for four or five days without relief. She was easily hypnotised, and one evening, while in the hypnotic condition, she was given a teaspoonful of pure water with the suggestion that it was a bitter dose, but very powerful, and would give a very free movement from the bowels at seven o’clock the following morning. She took the water with many grimaces at its bitter taste, and the suggestion was realised with great promptness and energy at exactly seven o’clock in the morning. I could give equally striking examples of the prompt effect of suggestion upon the menstrual function, and upon lactation.”
