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 tlie 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 tne ' westward, veering from N.VV. to S.S.W j the force was greatest on the night of the Bth (N.W.) There was also a heavy gale from the W.S. W. on the 22hd and 23rd. Barometer —The mean pressure was 29.98S nches (reduced to sea level and standard temperature of 32 deg. Fahrenheit and corrected for capillary action) the highest yet recorded. The reading waa above 30 inches on no fewer than 18 days in the month j the maximum waa 30.331 inches on the 3rd,. the minimum, 29.1*9 inches on |he 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 iv March. Hygrometer —Tlie mean degree of atmospheric humidity -was .79 —1.00 representing complete saturation waa attained on 11 days. The mean temperature of evaporation was 49.9 deg., and oi the dew point, 46.8 deg. Evaporation —Amount 2.311 inches, about half the precipitation. Radiation —Greatest solar 105 deg., on 14th tern stiai 24 deg., on 31st. Oioud —Amount (mean) 0.60, 1.00 indicating total obscuration. Wind —General direction, W. N.W. and S.E., mean force 6. (1.12) Note.—l shall shortly publish a full report oi my operations taken in 1865, as compared with tne seven years average. ■■
