Dr. Dougall's treatment of Leprosy, with this agent, consists in the use, internally, of a mixture of one part of the balsam and three parts of lime-water, and, externally, a mixture of equal parts of balsam and lime-water. The details of the treatment are as follows: The patients rose at half past five, and taking a quantity of dry earth with them repaired to the banks of a neighboring stream. Here they bathed, rubbing themselves freely with the earth as they would with soap. At seven o'clock they returned to their barracks and received a half-ounce dose of the balsam mixture, and in addition a quantity of the external mixture, with which they thoroughly rubbed their bodies during the space of two hours. At nine o'clock they breakfasted, and after that were employed at different kinds of labor.

At three o'clock in the afternoon they again took half-ounce doses of the mixture, and rubbed themselves for two hours with the external application. Great benefit is said to have been derived from this treatment in spite of the meagre food supplied to the patients, their diet consisting chiefly of rice, a few vegetables, a little fish and curdled milk.
