_3d._--M. H. Her father had been several times insane; her mother was likewise so affected a few months before her death. Afterwards her father married a woman perfectly sane, by whom he had three children, two female and a male; both the females are melancholic, the male was a vicious character, and has been transported. M. H. has had ten children, three have died with convulsions, the eldest, a girl, is epileptic. _4th._--T. B. His mother became insane soon after being delivered of him, and at intervals has continued so ever since. He has a brother who became furiously mad at the age of twenty, and afterwards recovered. T. B.'s disorder came on at the age of twenty-six. _5th._--S. F. Her father's mother was insane, and confined in the hospital. Her father never discovered any symptoms of insanity, and her mother was perfectly sane. Her only sister (she had no brothers) was mad about five years ago, and recovered. S. F. has been twice in the hospital. _6th._--P. W. After the best enquiries it does not appear that her father or mother ever experienced any attack of madness or melancholy. P. W.'s disorder commenced shortly after the delivery of a child. She has three sisters, the eldest has never been married, and has hitherto continued of sound mind. The two younger have been mothers, and in both insanity has supervened on childbearing. _7th._--J. A. H. His father's father was insane, and his father was also disordered, and destroyed himself. His mother was of sound mind. J. A. H. became insane at the age of twenty-three. He has two sisters, the elder has once been confined for insanity, the younger is of weak intellects, nearly approaching to ideotism. _8th._--M. D. Her mother was insane and died so. M. D. continued of sane mind until she had attained the age of fifty-seven, when she became furiously maniacal; her only daughter, eighteen years of age, was attacked with mania during the time her mother was confined. _9th._--G. F. His mother was melancholic during the time she was pregnant with him, and never afterwards completely recovered. She had five children previously to this melancholic attack, who have hitherto continued of sound mind. She bore another son after G. F. who is extremely flighty and unmanageable. G. F. was attacked with madness at the age of nineteen, and died apoplectic, from the violence and continued fury of his disorder.
