The highest temperature in the year occurred on July 19th, being 930 in the shade; the lowest, on the morning of February 24th, being 60. The coldest day, was January 22d, the mean temperature being 13.30. The barometer was highest at 1 P. M., October 28th, being, after reductions as above, 30.70 inches; the lowest, at from 9 to 10 A. M. on the morning of March 27th, being 28.63 inches. This is the lowest point which my barometer has reached in 18 years. 1848. The highest temperature occurred at 1 P. M. on the 16th of June, being 910 in the shade; the lowest, on the morning of January 11th, being 4 degrees below zero. The preceding day, the 10th, was much the coldest day in the year, the mean temperature being only 5.30, with a piercing wind all day from the northwest. The barometer was highest April 3d, being, when reduced, 30.68 inches. The lowest point occurred February 5th, from 9 to 11 P. M., being 28.93 inches. * The hour of the morning observation is 6 A. M. from the 1st of March to the 1st of October; during the remainder of the year, at sunrise. Annual Means,. NOTE. The barometric observations prior to May, 1847, were made with a good common barometer, and are reduced to the sea-level, and corrected for index error, but not for ca. pillary action or temperature. Since that period I have used a standard cistern barometer, made by J. H. Temple, Boston, and fitted with a screw for bringing the surface of the mercury in the cistern to a contact with an ivory point, and a microscope for the adjustment of both the upper and lower surfaces, and for the " reading off." The interior diameter of the tube is nearly three tenths of an inch, and the readings are to hundredths of an inch, and are uniformly taken at the top of the convexity of the mercury. The correction for the sea-level was determined by experiment. Its approximate value is +.13 of an inch. * Observations were omitted on several days in this month. 10 4.82 23 3.8 3.6 2.8 3.4 3.80 15 3.9 4.1 3.5 3.8 2.40 12 4.1 3.6 2.8 3.5 0.90 5.00 3.80 5.0 1.85 5* 4.7 4.0 3.3 4.0 5 3.73 4.1 4.8 3.0 5.3 2.45 5.4 4.9 5.4 5.2 767364LBSTB |
