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.

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.
