Algarovilla, an astringent substance, produced by the tree juga Marthœ, an acacia, found at Santa Marta in New Granada. The portions taken to England, and examined by Dr. Ure, were pods bruised and agglutinated with the extractive exudation of the seeds and husks. It is replete with tannin, and for tanning leather possesses more than four times the strength of good oak bark. It is also well adapted for the manufacture of black ink, for a yellow dye, and for an astringent medicine.
