    THE most recently published annual volume of the Weekly Weather Report (The Weekly Weather Report for the Period February 26, 1933 to March 3, 1934. M.O. 374. London: H.M. Stationery Office. 7s. 6d., postage extra) is the fifty-sixth that has appeared since the publication of meteorological data in weeks by the Meteorological Office was first begun, and is the fifth in which the data are largely presented in the form of deviations from normal values of the different elements. The deviations of temperature are given in whole degrees, of accumu lated temperature (reckoned from 42° F., the zero of temperature from the point of view of plant growth) in day degrees, while for rainfall and sun shine the percentage of the normal for the appropriate week or season is quoted. This report is designed to be used for correlation with agricultural data, for which as a time unit the day is regarded as being too short, and the month too long. The year begins and ends, as in former volumes, with early spring, the whole period under review in this case beginning on February 26, 1933, and ending on March 3, 1934, and the tables are based on the records of fifty-seven stations well distributed throughout Great Britain and Ireland. The time of commencement was for England within a wet period following a remarkably dry winter, which came at a favourable time for agriculture in so far as it supplied the land with some reserves of water, and enabled many crops to withstand the drought, heat and abnormal sunshine of the summer and autumn of 1933 far better than they would have done had the winter drought not had this pronounced check. The period as a whole was with few exceptions one with excess of sunshine over England, especially in the south-east and the Midlands. There was general dryness and warmth throughout the British Isles, t the warmth being especially pronounced in spring and summer; July and August provided more than one spell of tropical heat, without however quite repeating the very exceptional extremes of the August of the preceding year.
