This state of instability lasted for several days until the patient became somewhat familiar with the surroundings. In one of her better moments the patient told me that she thought her stammering began with a definite event. One evening when she was fatigued with the labors of the day for her family, a stammerer came in to see her. The stammering made a strong impression on her. She felt the strain of the stammerer; she could not control the sympathy and the strain, and involuntarily began to imitate stammering. She began to fear that she might continue to stammer and be unable to enunciate sounds and words. The more she feared the harder it was for her to speak or even to use her voice. A few days later the patient began to improve, she began to adapt herself to her surroundings, and did not get so easily scared. About eight days after the first examination the patient woke up one morning in a state of depression; she cried a good deal. She did not sleep well the night before, dreamt and worried on account of her children. She was afraid that something might have happened to them in her absence, perhaps they were sick, perhaps the husband could not take good care of them. She talked in a whisper, her eyes were shut. When I insisted on opening the eyelids, she opened them, but did it with difficulty. I put her into a hypnotic state. In about a minute her eyes rolled up, and the eyelids shut spasmodically. There was present a slight degree of catalepsy. Mutism was strongly marked. Upon sudden and unexpected application of an electric current, the patient opened her eyes, cried out, but soon relapsed into a state of lethargy. Gradually patient was brought out of the lethargic state. A couple of hours later, after she had a good rest a few more experiments as to her sensori-motor life were attempted. I asked her to raise objects, tested her sensitivity to various stimulations, her concentration of attention, asked her questions about her life, about her family, took again her field of vision. All that was a great effort to her. While I was taking her field of vision the patient’s eyes began to close, and it took about twenty seconds before she could open them. She opened them with effort, but shut them again. This time it took her about 45 seconds before she could open the lids. Fatigue, or rather fear fatigue, set in sooner with each repetition of experiment and test, and lasted a longer time.
