Abstract
THE Royal Meteorological Society's Phenological Report for 1939 has been issued with its usual abundance of statistics and diagrams (Roy. Meteor. Soc, London. 3s.) It is interesting to note that the work is to continue, despite the War, and that other organizations like the British Empire Naturalists' Association and the Rothamsted Experimental Station are co-operating. There is a total of 385 observing stations compared with 439 in the previous report, and a scheme has been prepared to meet the growing demand for a simple method of assessing and demonstrating, at intervals throughout the year, the state of the season in the British Isles, making use of the Society's organization. In order to replace some unsatisfactory plants on the list, flowering dates are being made for the first time of Cardamine pratensis, Acer pseudoplatanus, Viburnum opulus, Digitalis purpurea and Calluna vulgaris. The historic phenological observations at the Marsham district of Norfolk, which have been made since 1736, are being continued.
