" The nim or margosa to-day is an important therapeutic agent and requires a special notice. The toddy or sap is yielded either spontaneously or extracted artificially. In the former case, a clear and colorless liquid begins to flow in a very thin stream or continuous drops, from two or three and sometimes more parts of the plant, and continues to do so from three to seven weeks.

After the last or fourth occasion, the trunk became rapidly hollow and the plant died soon after this. On each occasion, before the sap began to flow, there was always, for three or four days, a distinct and peculiar rushing or pumping noise of a liquid within the trunk, which did not entirely cease till the discharge actually commenced from three or four parts of the plant.
