Table of Rain, Snow, Fair Days, and Wind. 



January. The severity of the cold during the month was remarkable ; 

 the minimum of the thermometer 28° degrees below the freezing point, and 

 the mean was much lower than for the last seven years. The barometer 

 has not been so high since 1826, and the range was the contrary of that 

 noticed last month, being nearly two inches. Snow fell on the llth, 12th, 

 13th, 19th, 20th, 21st, 23d, 27th, 29th, 30th, and 31st, and sleet on several 

 other days. The whole, if added together, would give a depth of 19 inches. 

 The rain and melted snow measured 2*61375 inches. A partial thaw com- 

 menced on the 25th and 26th, but the frost returned on the following day. 

 The evaporation 0'0625 of an inch. 



February. The early part of the month was very cold, attended by 

 snow. On the 5th, at night, the thermometer stood at 2° 25', which was 

 much colder than for many years in the same month. A thaw commenced 

 on the 7th, and rain fell on eight different days ; the greater part on the 

 7th and 8th, and on the 21st and 22d. The whole quantity of rain 

 and melted snow 2*36875 inches, which was more than since February 

 1826, which was remarkably wet. There were five snowy days, and the 

 whole depth was about 4*5 in. The mean of the barometer lower than 

 last year, and the range less than usual. The evaporation 008 125 of an 

 inch. 



March. The month was particularly fine, and the thermometer rose to 

 a height not experienced at Wycombe during the last seven years : the 

 mean temperature was also much above those of the same period. The 

 last six days had more the appearance of summer than of spring; but in 

 the night of the 31st an extraordinary change took place, and rain, sleet, 

 and snow fell. The whole quantity of rain and melted snow was small for 

 the month, though much more than last year. The barometer was con- 

 siderably higher than usual, and the mean 0*24 of an inch above that of 

 March 1829. The evaporation 0*55625 of an inch. 



April. Rain fell on fourteen days, and the quantity was great for the, 

 season, thoiligh not equal to what was experienced in April last year, which 

 was an extraordinarily wet month. The mean temperature considerably 

 higher than since 1825, and the extremes of heat and cold greater than in 

 any one of the corresponding months of the last seven years. The baro- 

 meter was generally higher than for the last two years, although the maxi- 

 mum did not reach the average. A rainbow seen on the 23d, about 3 P. M., 

 and soon after thunder was heard. The evaporation 0*475 of an inch. 



May. The month was not so warm as in the last two years, although 

 the maximum was much higher than usual, and the range 47°. The baro- 

 meter has not been so low in the month of May since 1827, as it respects the
