Miss S. W., 15 1/2 years old. Reformed Church. The paternal grandfather was highly intelligent, a clergyman with frequent waking hallucinations (generally visions, often whole dramatic scenes with dialogues, etc.). A brother of the grandfather was an imbecile eccentric, who also saw visions. A sister of the grandfather, a peculiar, odd character. The paternal grandmother after some fever in her 20th year (typhoid?) had a trance which lasted three days, from which she did not awake until the crown of her head had been burned by a red-hot iron. During states of excitement later on she had fainting fits which were nearly always followed by a brief somnambulism during which she uttered prophesies. Her father was likewise a peculiar, original personality with bizarre ideas. All three had waking hallucinations (second-sight, forebodings, etc.). A third brother was also eccentric and odd, talented but one-sided. The mother has an inherited mental defect often bordering on psychosis. The sister is a hysteric and visionary and a second sister suffers from "nervous heart attacks." Miss S. W. is slenderly built, skull somewhat rachitic, without pronounced hydrocephalus, face rather pale, eyes dark with a peculiar penetrating look. She has had no serious illnesses. At school she passed for average, showed little interest, was inattentive. As a rule her behaviour was rather reserved, sometimes giving place, however, to exuberant joy and exaltation. Of average intelligence, without special gifts, neither musical nor fond of books, her preference is for handwork--and day dreaming. She was often absent-minded, misread in a peculiar way when reading aloud, instead of the word _Ziege_ (goat), for instance, said _Gais_, instead of _Treppe_ (stair), _Stege_; this occurred so often that her brothers and sisters laughed at her. There were no other abnormalities; there were no serious hysterical manifestations. Her family were artisans and business people with very limited interests. Books of mystical content were never permitted in the family. Her education was faulty; there were numerous brothers and sisters and thus the education was given indiscriminately, and in addition the children had to suffer a great deal from the inconsequent and vulgar, indeed sometimes rough, treatment of their mother. The father, a very busy business man, could not pay much attention to his children, and died when S. W. was not yet grown up. Under these uncomfortable conditions it is no wonder that S. W. felt herself shut in and unhappy. She was often afraid to go home, and preferred to be anywhere rather than there. She was left a great deal with playmates and grew up in this way without much polish. The level of her education is relatively low and her interests correspondingly limited. Her knowledge of literature is also very limited. She knows the common school songs by heart, songs of Schiller and Goethe and a few other poets, as well as fragments from a song book and the psalms.
