Characteristics.-Hale gives this indication of Zn. pi. Cerebro-spinal troubles of the erethistic character." Hugh Pitcairn (quoted H. W., xix. 366) gives these indications: (1) Brain-fag. (2) Nervous exhaustion from over-worked brain or sexual excess. (3) Chronic occipital headaches, periodic. (4) Headache occurring in Bright's disease. (5) Threatened cerebral paralysis, especially in children. (6) Profound neurasthenia, when nervous exhaustion has passed beyond stage of erethism. (7) Seminal emissions. (8) Erotomania. He gives this case: Mr. M., 36, merchant. Above ordinary intelligence. Single; correct in his habits, but subject to seminal emissions since early manhood, occurring about 3 a.m. every third night, leaving him very weak and debilitated; < every change of weather, especially in hot weather and before and during thunderstorms.
