This condition may accompany either menor-rhagia or amenorrhoea, and that arsenic may remedy either symptom is, therefore, not contradictory. In the former, the catamenia being too copious and too frequent (leucorrhoea often occurring in the intervals), and the patient becoming weak and anaemic, small doses of from 2 to 6 min. thrice daily will be found to lessen the flow and to improve appetite and general health. Mr. Hunt has recorded some striking cases of uterine hemorrhage at various intervals after labor or miscarriage, some accompanied with symptoms only of irritable uterus, "but for the most part atonic in character" (Medico - Chirurgical Transactions, vol. xxi.); all improved under arsenic. Sir C. Locock found great advantage from it in similar cases. Dr. A. Burns, from experience of it in all varieties of uterine hemorrhage, has reason to express the greatest confidence in the remedy, and records several cases treated by rather large doses, 10 to 20 min. repeated every fifteen to twenty minutes (American Journal Medical Sciences, October, 1859).
