Some facts we obtained on the family history were most significant. The mother of William suffered from attacks which were undoubtedly epileptic. Her mother, in turn, had convulsions at least during one pregnancy. We did not learn whether or not she had them at other times. No other points of significance in that family are known. The father himself was brought up, as he says, strictly, but he was inclined to be wild, and he has indulged for many years altogether too much in tobacco and alcohol. He is distinctly a weak type and the poorest specimen of his family. William is the only child. There was nothing peculiar in developmental history until he was 2 1/2 years old when he suffered from ``brain fever and spinal meningitis.'' This was said to have left him with a stiff right arm and to account for his being left handed. (We could discover no difference in the reflexes.) Then at another period he was sick in bed for 6 months with some unknown, but not very serious illness. The mother has been dead for years and so we were unable to get accurate details about this. At a very early age William sought the pleasures of tobacco, even when a child of 6 or 7 he used his pennies for that purpose. He was brought up in an environment defective on account of his father being a poor earner and weak in discipline. But still his parent took for years a great deal of interest in him and it was not until the boy had proven himself most difficult that his father proclaimed himself unable to manage his son.
