be somewhat rare, to judge by its infrequency in German literature on the subject. So-called spontaneous somnambulism, resting upon a foundation of hysterically-tinged psychopathic deficiency, is not a very common occurrence and it is worth while to devote closer study to these cases, for they occasionally present a mass of interesting observations.
Case of Miss Elise K., aged 40, single; book-keeper in a large business; no hereditary taint, except that it is alleged a brother became slightly nervous after family misfortune and illness. Well educated, of a cheerful, joyous nature, not of a saving disposition, she was always occupied with some big idea. She was very kind-hearted and gentle, did a great deal both for her parents, who were living in very modest circumstances, and for strangers. Nevertheless she was not happy, because she thought she did not understand herself. She had always enjoyed good health till a few years ago, when she is said to have been treated for dilatation of the stomach and tapeworm. During this illness her hair became rapidly white, later she had typhoid fever. An engagement was terminated by the death of her fiancé from paralysis. She had been very nervous for a year and a half. In the summer of 1897 she went away for change of air and treatment by hydropathy. She herself says that for about a year she has had moments during work when her thoughts seem to stand still, but she does not fall asleep. Nevertheless she makes no mistakes in the accounts at such times. She has often been to the wrong street and then suddenly noticed that she was not in the right place. She has had no giddiness or attacks of fainting. Formerly menstruation occurred regularly every four weeks, and without any pain, but since she has been nervous and overworked it has come every fourteen days. For a long time she has suffered from constant headache. As accountant and book-keeper in a large establishment, the patient has had very strenuous work, which she performs well and conscientiously. In addition to the strenuous character of her work, in the last year she had various new worries. The brother was suddenly divorced.
