The notes of a case—an epileptic female suffering from complicated delusional insanity—are given to show the preponderating influence of dreams upon the mental life. E. V—, now æt. 45 years, was brought up as a child under unsatisfactory conditions (family quarrels, unkind mother, etc.). She was married at the age of twenty-six, and took to gambling. She had her first epileptic fit when thirty-one, after a violent emotional shock (witnessing the paternal house on fire); it was followed by disordered mind for forty-eight hours. Subsequently fits recurred for a time every six months, always followed by short periods of mental disorder; then they became more frequent. When thirty-seven, after an attack, she developed hypochondriacal ideas and delusions of persecution with auditory and sensory hallucinations, on account of which she was sent to an asylum.
