METEOROLOGICAL OBSERVATIONS, MARCH, 1866.

A most unfortunate month, for the harvest, which is late beyond sll precedent. Although the barometer was remarkably high and steady, the air was constantly saturated with moisture, he maximum point of the hygrometer being reached on no fewer than eleven degs. .The air was extremely cold as well as damp. The mean temperature was more than four degrees below the seven years' average, and on the 31st. the depression below the average was as great as 19 degrees. Heavy falls of rain occurred, the amount being respectively 1.155 inch, 1.024 inch, 0.853 inch. During the first twelve days the equinoctial gales blew very strongly from tlie westward, veering from N.W. to S.S. W ; the force was greatest on the nighfc of the Bth (N.W.) There was also a heavy gale from the W.S.W. on the 22nd and 23rd. Barometer — The mean pressure was 29.988 nches (reduced to sea level and standard temperature of 32 deg. Fahrenheit and corrected for capillary action) the highest yet recorded. The reading was above 30 niches on no fewer than 18 days in the month ; the maximum was 30.331 inches on the 3rd, the minimum 29.149 inches on the sth. . . Thermometer — The mean temperature of the air was 53.1 ; the lowest on record in March, and 4.2 degrees below the average of seven previous years. The highest day temperature was 74.6 deg. on the 14th, the lowest night, temperature 25 deg. on the 31st, the severest frost ever known in March. Hygrometer — The mean degree of atmospheric humidity was .79 — 1.00 representing completesaturation was attained on 11 days. The mean temperature of evaporation was 49.9 deg., and of the dew point, 46.8 deg. Evaporation— Amount 2.311 inches, about half the precipitation. Radiation — Greatest solar 105 deg., on 14th temstial 24 deg., on 31st. Cloud — Amount (mean) 0.60, 1.00 indicating total obscuration. Wind— General direction, W. N.W. and S.E., mean force 6. (1.12) Note. — I shall shortly publish a full report of my operations taken in 1865, as compared with the seven years average.
