THE WEATHER REPORT.

The concluding part of the month of March has been principally" marked by a lower range of the barometer, by a perceptible diminution of 'the temperature, and by showery -weather,-three-fifths o£ the month's rain having fallen during this period. The barometer has fluctuated considerably, having risen and fallen two or three times, though not through any very great distances, ranging between 29-909 on the 24th, and29-G39 on the 22nd, with an average of 29-783, which is much below the results obtained for the commencement and middle of the month, and also lower, than the, average of the twelve years past. The temperature > has been very much, lower, the mean of the eleven days being no less than SJ-degrees. less than that of the middle of the month, and 6-7 degrees below that of the : commencement;' the day heat, much the same, but on four occasions the' night temperature has fallen below 50 deg.; and the average range has been much greater than it was a' little , J time back. A similar difference is to be noticed with the wet-bulb instruments, and with the terrestrialTadiation thermometers, cdl which give inean' readings at from 4 to 5 degrees below those of the last decade, while that of the solar radiator is not less than. 9 degrees lower. Rain- has fallen on seven days out of the eleven, and though less was registered for anv six hours than was recorded on the 2nd of the month, yet the total fall, as already mentioned, amounts to three-fifths of the entire quantity registered during the month. The wind has continued mostly lighter, bnt varied in direction, every change from N.E: by S. to IT.'W. having been noticed, and only on two consecutive days was it constant to the same quarter. The general barometic average for the month of March has , been 30 025," corresponding very'closely with that deduced from the 12 years previous. The range, following the precedent of 1574 and 1575, has been greater than in the three preceding mouths of summer; the oscillations, as a whole, have been frequent; rather than violent, the maximum having been reached at 30 - 461 on the 13th, andthe minimum: at 29-G39 on the 22nd, The approximate mean, temperature for the month > has been 65 - S'; the. mean of the twelve years being .65-6; the .day heat has only once reached SO % and only four times fallen below 70\ The night thermometer has given a wider range,—on ten occasions making 60or upwards, and on four nights less than 50\ As usual, these occasions of lowest day and lowest night temperature by no means correspond. The approximate mean of the wat bulbs is 61-3, whence we obtain a dew point at 57'6, with a degree of humidity equal to 75% being a little more than February, though a good deal less t than January. According, we, find the rainfall to be 2045 inches in IS.days, with; a minimum of GUO inches on the..2nd; that of February being 1140 inches in eight days, and that of J anuury 4235 in fourteen days respectively.Asharp but short hail shower, however, fell on the afternoon of the 23rd. The wind has been very variable, blowing from all points of the compass, though' less from N.W. and JST. than from every other. Its average velocity has been 301 miles per diem, or 12J miles per hour; its maximum (on the 2nd), 636 miles or 26iinil(!s per hour. The amount of morning cloud noted has differed little from that of February.
