On this chart we have the history of an +epileptic+ man whose attacks were of the petit-mal type. He married a choreic woman. They had four children, the eldest a man who developed epilepsy after his second marriage. His first wife was insane; by her he had two daughters, one of whom is now an inmate in an insane asylum, the other is neurotic and has been treated in a sanatorium. Of the other children two are apparently normal and one migrainous. [Sidenote: D 12] This chart shows an +epileptic+ man married to a normal woman; he had both epileptic and insane relatives, while she had epileptic, alcoholic, and tubercular relatives. Their first child was an epileptic, the next were twins, one of these appears to be normal while the other is of a very nervous temperament, the fourth died in infancy, and the last three were stillbirths. The mother married the second time, this time to a man who drank to excess after their marriage; by him she had two children, both of whom seem to be normal. They are both in school. [Sidenote: D 13] This is the history of a low grade +epileptic+. His oldest sister is normal; she was brought up by strangers after her mother's death, and is now earning her living as a saleslady. The second was a boy, who was thought to be normal until he was about sixteen, when he displayed criminalistic tendencies, and for the crime of rape was put in the Reform School. The youngest is a girl, who is of a very nervous temperament. The father was an alcoholic, and went on long sprees; he deserted his wife and family to live with a woman who also deserted a family. His brother is an alcoholic, and married the patient's mother's sister; they are now divorced. The mother was migrainous, she died of tuberculosis; her family shows a neurotic taint, while the father has several epileptic relatives. [Sidenote: D 14] In the central mating the father and mother are both +migrainous+. They both belong to families prominent in the community in which they reside; their homes are among the best, and they are counted as leading citizens. There were nine children; three died before four years of age, one is epileptic, one seems to be normal, and the others all show some nervous taint, though not migrainous. [Sidenote: D 15] This is the history of a +syphilitic and a sexually immoral couple+. They were never married, and the woman for many years supported the man, who was never sober and frequently had attacks of delirium tremens. She finally deserted him. Of their eight children two were stillbirths, three were epileptic, and the other syphilitic. One of the epileptics in a jealous rage shot the woman whom he loved, and when he found that escape was impossible, killed himself.
