Two days afterwards my patient brought me several small brownish particles, having the appearance of fine sand. When crushed and pressed between the fingers they had a decidedly gritty feel. Under the microscope they had the appearance of rough coarse sand. The discharge of calculi kept up for nearly a week, under the use of the _Epigea_, and then ceased, and with it all the symptoms of irritation of the bladder. It is just possible that the discharge of gravel may have been a coincidence. It is equally possible that the _Lycopodium_ acted curatively; but I am inclined to believe their disintegration and expulsion was caused or aided by the use of the last medicine. Further observations are needed to place the curative powers of this plant on a certain basis. ERYNGIUM AQUATICUM. NAT. ORD., Umbeliferæ. COMMON NAMES, Button Snakeroot. Water Eryngo. PREPARATION.--The fresh root is pounded to a pulp and macerated in two parts by weight of alcohol. (Although a well-known remedy, the following concerning its early history may not be out of place here. It is from Thomas' _Additions_.) "For spermatorrhoea properly so called, or emission of semen without erections, there is no remedy which has yet received the sanction of experience."--_Repertory._ "We have one, however, to propose for trial--it is the _Eryngium aquaticum_, which has two remarkable cures, reported by Dr. Parks (Pharmacentist, Cin.), to recommend it. "CASE I.--A married man injured his testicles by jumping upon a horse; this was followed by a discharge of what was considered semen for fifteen years, during which time he was treated allopathically and homoeopathically. Dr. Parks exhibited a number of the usual remedies without permanent benefit. He then gave a half-grain dose, three times a day, of the third decimal trituration of the '_Eryngium aquaticum_.' In five days the emissions were entirely suppressed, and have not returned to this time (over two years ago). The emissions were without erections day or night, and followed by great lassitude. "CASE II.--A married man, not conscious of having sustained any injury, was troubled for eight or ten years with emissions at night--with erections. The semen also passed by day with the urine. The loss of semen was followed by great lassitude and depression, continuing from twelve to forty-eight hours. There was also partial impotence. Had been treated allopathically. Dr. Parks gave him Phos. acid for two weeks, without material benefit. He then exhibited the _Eryngium aquaticum_, as above, with the like excellent and prompt result."[I] [I] Drs.
