As in February, 1905--which, however, was a mild month--the amount of cloud was relatively small, and sunshine was in excess. The duration of bright sunshine was estimated at 92s5 hours, or a daily average of 3s3 hours, compared with 79s25 hours, or a daily average of 2s8 hours in 1902, 63s5 hours or a daily average of 2s3 hours in 1903, only 43 0 hours or a daily average of 1s5 hours in 1904, and 97 hours or a daily average of 3s5 hours in 1905. In Dublin the mean temperature (397) was 2s8 below the average (42s5). The mean dry. bulb readings at 9 a.m. and 9 p.m. were 38 2. In the forty-one years ending with 1905, February was coldest in 1895 (M. T. = 34s2), and warmest in 1869 (M. T.=467) and in 1903 (M. T.=47s5). In 1902 the M. T. was 39s3; in 1903, 47 5; in 1904, 407; and in 1905, 43 6. The mean height of the barometer was 29764 inches, or 0 091 inch below the average value for February--namely, 29 855 inches. The mercury rose to 30s415 inches at 9 a.m. of the 7th, and fell to 28s568 inches at 4.15 p.m. of the 10th. The observed range of atmospheric pressure was, therefore, 1s847 inches. The mean temperature deduced from daily readings of the dry-bulb thermometer at 9 a.m. and 9 p.m. was 38s2, or 4s8 below the value for January, 1906. Using the formula, Mean Temp.= Min. + Max.--Min.) x s50, the M. T. is 397, compared with a thirty years' (1871-1900) average of 42 5. On the 1st the thermometer in the screen rose to 501--wind, W.; on the 12th it fell to 29s1--wind, N.W. The minimum on the grass was 24s2 on the 21st.
