Abstract
WORK on the chemical composition of the various parts of fruit trees, particularly apple and pear, is proceeding at Long Ashton aud East Malling Research Stations and the Ditton Laboratory. The problems being studied are not quite the same in each laboratory, but discussions of common interests have disclosed certain overlapping findings. For this reason, we wish jointly to report the presence of chlorogenic acid in both mature and immature apple and pear fruits, and of this substance and a substance similar to, or identical with, isochlorogenic acid of coffee1 in leaves and shoots of pear.
