180 Calendar of Nature, 



January. The month was colder than in 1827 or 1828, and the quantity 

 of rain and melted snow considerably less than in January, 1827, and not 

 a fourth part of that in 1828. The mean of the barometer lower than for 

 the last 7 years. Snow fell on six different days, the whole quantity 

 about 1*75 in. in depth. A beautiful lunar halo observed on the 17th, about 

 11 P.M. The evaporation 0*08125 of an inch. 



February. The temperature of the month was below those of the last 

 2 years, according to the mean^ but the extreme of cold was not so great 

 as in 1827, though 10*25° below that of last year. The barometer higher than 

 since February, 1825. The quantity of rain nearly the same as in the cor- 

 responding month last year. The weather generally dull and bleak, with 

 the wind mostly from the northward and eastward. The evaporation 

 0*00625 of an inch. 



March. Less rain fell (only on five days) than even in March last year, 

 which was distinguished by extreme dryness. The mean temperature 

 lower than since 1823, and the extreme cold greater than any, observed by 

 the journalist, in the same month, during the last 12 years. The barometer 

 below the mean of last year, though above that of 1827. Very few bril- 

 liant days occurred, and the weather was generally dull, cold, and bleak. 

 A lunar halo, with misty area, seen on the night of the 16th. The evapo- 

 ration 0*2 of an inch. 



April. The month commenced with snow ; about 1*5 in. fell on the night 

 of the 1st, and the whole month was extremely cold; the mean tempe- 

 rature being below any one in April since 1823, and more than 3° lower 

 than the average of the last 12 years. Rain, with the snow on the 1st, 

 fell on 24 different days, the whole quantity remarkably great, exceeding 

 that of last year by nearly an inch. The mean of the barometer lower 

 than for many years, although the range was not very great. Very heavy 

 gales of wind at the latter end of the month, particularly on the 28th, 

 which were similar to those frequently experienced at the equinoxes. 

 Thunder heard on the 10th about 2 P.M. The evaporation 0*08125 of an 

 inch. 



May. During the whole month the barometer was remarkably high, 

 ^nd the mean much above any one in the last 13 years. The quantity of 

 rain less than in 1818. Nearly 1*5 in. more fell in May, 1828. The weather 

 generally fine, yet the mean temperature did not reach either of those of 

 the last 2 years. An indistinct lunar halo' seen on the 10th, about 

 10 P.M. A heavy gale of wind from the northward on the night of the 

 25th. The evaporation 0*60625 of an inch. 



June. In the early part of the month there was much threatening wea- 

 ther, yet but little rain fell until the latter end, when there were frequent 

 heavy showers, vipwards of 1 in. fell on the 27th, and nearly as much on 

 the following day ; the whole quantity more than since 1824. The tem- 

 perature much below June last year, the range of the thermometer 40°, and 

 the minimum only 2*5° above the freezing point. The mean and extremes 

 of the barometer rather above those of June last year, and the average of 

 the month. On the 25th a slight thunder storm, with some little lightning 

 between 2 and 3 P.M. An indistinct lunar halo, with misty area, observed 

 on the night of the 9th. The evaporation 0*45 of an inch. 



July. More rain fell in the month than in any July since 1823, the 

 weather of which month, in that year, it very much resembled ; the mean 

 temperature was very nearly the same ; the maximum of heat lower than 

 usual, and the minimum about the average. The barometer higher than 

 last year, although lower than ordinarily in July, and nearly approximating 

 to the mean of 1823. Thunder heard on the 2d, 8th, 18th, and 24th. 

 Slight storms were experienced on the two last of these days, and tlie 

 lightning on the 24th (about 12 P.M.) was very general, but not extremely 

 vivid, and for some little time the rain fell with extraordinary rapidity. On
