The perchloride is not only frequently of service as a styptic injection into the rectum to relieve bleeding from internal haemorrhoids, but has been used sometimes by direct injection into the tumors, and has cured when other expedients have failed (Colles: Dublin Journal, June, 1874). Monsel's solution succeeded equally well in two cases of large external piles under Mr. Morgan (Medical Press, 1869). Haemorrhoids occurring in anaemic or debilitated patients with copious bleeding, are in my experience often well treated by the internal administration of the perchloride.
