Abstract
FROM time to time instances of this in the case of foliage have been recorded by correspondents in the pages of NATURE. This year I have noticed not only an unusually early appearance of this in the development of new foliage-laden twigs, as in farmer years in the oaks, the hornbeams, the elms, and other forest trees; but, what is more rare with this somewhat exceptional summer, the fruit-trees seem to be expending their reserve energy in a second season of flowering. At this moment an apple-tree in my garden presents the curious sight of apple-blossoms side by side with apples more than half-grown, and a rowan-tree laden with nearly ripe fruit has a corymb of flowers on one of its higher boughs. The plum-trees have presented similar abnormal phenomena within the last week or two. The facts are of interest as pointing to considerable interference with the normal cycle of functional change by variations in environment.
