It was imported from Mexico and was the produce of a tree called Zapota, doubtless of the order Sapotaceae which produces Gutta Percha but the specific name was not given. My correspondents state that the, gum Chicle was used in New York for manufacturing chewing gum, but were under the impression that firm there had discovered an important use for it in combination with rubber and for insulating cable wires. The price at that time 40 pounds sterling per 1, 00 lbs net cash. It was thought that an essential oil adapted for perfumery could be extracted from this gum and it was stated that a substance known in the materia Medica as Monesia was extracted from it. Some experiments were also made with it, with a v, iew of manufacturing a paint for vessels bottoms.
