N. E., aged 22, primipara. Called at nine o'clock in the morning and found patient with light pains and os open the size of a twenty-five-cent piece. Hypnotic state induced, and suggestion given that when I came to see her again when labor was well established that she would close her eyes and go to sleep, and feel no pain. At ten o'clock in the evening I was called, and when I told her to close her eyes and go to sleep, and made other suggestions to get her into a deep state of suggestibility, she easily went into the hypnotic state and was completely amenable to suggestion.
She would extend her hands to receive help from an assistant and bore down with every contraction, but her expression showed no evidence of pain. She did not get nervous, and did not know when the child emerged until I told her to wake up and look at her baby.
