moved southwestward to Czechoslovakia, Prague, 30.42 inches; and the LOW over the Mediterranean had remained practically stationary, but wit,h a slight increase in intensity, and heavy snow and violent gales occurred in Constantinople. On the morning of the 3d snow was reported at Palermo, Sicily. Canals in Holland had frozen over. By February 8 the Mediterranean LOW had moved northeastward to Kustanai in the Province of Turgai where it rapidly dissipated; pressure increased over southern Europe and rem.ained high in the Provinces of Yakutsk and Irkutsk, Bargusink and Bratski-Ostrog, 31 inches, with an estension to the northwest, Obdorsk, 30.74 inches. By the morning of the llth, a LOW of considerable intensity had formed over the Mediterranean, Leghorn, Italy, 29.50 inches, and pressure had increased over northern Europe to 30.77 inches at Helsingfors. By the 12th, the Rhine, Lake Constance, parts of the Baltic, and the Elbe from Hamburg to Dresden were frozen. On the 15th ice floes were floating on the Grand Canal at Venice. High pressure in the north and low pressure in the south prevailed until the 23d of the month, when the high pressure finally gave way and cyclones were again permitted to take normal courses. One of the most striking features during the period of January 21 to February 21 was the great preponderance of positive pressure departures over the Northern Hemisphere. During most of the period pressures were above normal over most of the continental areas, the largest departures occurring over Central Asia, where, except for the last few days, pressures were 0.20 inch to 0.90 inch above normal. Negative departures were confined for the most part to rather small areas in northern oceanic regions.
