Clinical.-Colic. (Epilepsy.) Haemoptysis. Strangury. Toothache.

Characteristics.-In Germany Onis. has a popular reputation as a remedy for epilepsy. Hering proved a tincture, and Wolff recorded the effect of swallowing three "cellar-worms" in a glass of brandy before an attack of fever. This experience has provided the most characteristic symptoms of the remedy, showing it to be related to Cantharis, Apis, and their cognates. These symptoms were noted: Pale face, wild expression, constant vomiting. Very severe colic with meteorism and tension of abdomen. Tenesmus of bladder and rectum. Cutting burning in urethra. The symptoms of Hering's proving showed pains in the head, over the eyes, and down the nose. Constriction of gullet and stomach. Burning in anus. Many erections with disinclination to work. Hawking up of blood-streaked mucus. The last two symptoms again recall Canth. Frequent yawning and desire to stretch.
