Note 468 — PHARMACOLOGIA. (continued 3)

Cinchonia has been detected in other vegetables besides the Bark, as in the root of Cusparia, and in the berries of Capsicum, while in the bark of Cascarilla, a substance bearing a much nearer relation in medicinal effect to the Bark, its presence has not yet been discovered. It is said that experiments have been lately made by M. M. Robiquet and Petroz on the Bark of the Carapa, which has been successfully used in several parts of America in the cure of agues, and that they have found in that bark a salifiable basis analogous to Quina.
