THE Phenological Report for 1935 by I. D. Margary (Quart. J. Met. Soc., 62, No. 265) covers the period December 1934-November 1935 inclusive. That period was of unusual interest on account of two spells of exceptional weather?the very wet December of 1934, and the bitterly cold period of May 1935 when a strong flow of air from polar regions brought severe frosts and snowstorms down even to the coastal regions of the south of England. The early months of 1935 were, on the whole, mild, with the result that in most counties flowers appeared early. The wintry weather in May therefore caused damage to plants and trees on a scale that luckily can probably be seen only once or twice in an average lifetime. Insects reacted eccentrically to this topsy-turvy weather that preceded the setting in of true summer weather, and showed very variable dates for their first appearance. Migrant birds behaved likewise; ythe species that normally arrive early were in the south mostly much in advance of their average first appearance; those that usually arrive late, for example, the garden warbler and the spotted flycatcher, were nearly all abnormally late. The spotted flycatcher was, however, exceptionally early in reaching the northern parts of Scotland and Ireland.
