tixtreines, and the mean was less than last year. The quantity of rain wais 

 remarkably great, much more than in any of the corresponding months of 

 the last seven years, and more than seven times as much as in May, 1829. 

 On the 21st thunder was heard about midnight, attended by vivid light- 

 ning : there M^as also a slight thunder storm on the 23d, about 3 P. M., with 

 very heavy rain. Large hail on the 30th, in the afternoon, during a squall, 

 attended by thunder and some lightning. The evaporation 046875 of an 

 inch. 



June. So wet and cold a June, attended by so great a depression of the 

 barometer, has not occurred during the last eight years. The quantity of 

 rain was extraordinary, exceeding, by upwards of half an inch, the quantity 

 which fell in the same month last year, which was noticed as being par- 

 ticularly great, the mean temperature was upwards of 2*75 below the average 

 of the last seven years. On the 25th there was much lightning all round the 

 compass from 8 P.M. until midnight, but the thunder was not loud. An 

 indistinct lunar halo observed on the night of the 2d, about 10 P.M. The 

 evaporation 0*21875 of an inch. 



July. The commencement of the month was extremely wet, and the 

 greater part of the rain fell in the first eleven days, but the whole quantity 

 was little more than half of what fell in July last year ; the latter end of 

 the month was very fine, and the thermometer rose higher than 1826; the 

 barometer was also above the maxima and means of the last two years. 

 Thunder heard on the 3d, 7th, and 30th, and lightning seen on the 29th to 

 the northward. An indistinct rainbow seen on the 9th. The evaporation 

 0-69«75 of an inch. 



August. The latter end of the month was particularly cold, even colder 

 than in August last year, and although the quantity of rain was not one 

 half of what fell in the same month in 1828, and very considerably less 

 than the quantity last year, yet the mean temperature was lower than any 

 one for August in the last eight years, the greatest elevation of the baro- 

 meter the same as in the corresponding month last year, and the mean 

 rather higher, but low for the season. Thunder heard, and lightning seen, 

 on the 9th, about 2 P.M. The evaporation 0-3125 of an inch. 



September. Although rain fell on nearly as many days as in September 

 last year, the quantity was almost an inch less, and very little for the 

 month. The mean of the barometer below the usual average, yet higher 

 than last year, as were both the extremes ; the temperature generally low, 

 and on the night of the 21st only half a degree above the freezing point, 

 which was lower than the thermometer has been in September since 1824. 

 Thunder was heard on the 14th, about 3 P.M. The evaporation 0-13125 

 of an inch. 



October. The month was uncommonly fine, the quantity of rain con- 

 siderably less than during the last eight years, the mean temperature higher 

 than since 1827, and the maximum above any observed at Wycombe, in 

 October, during the journalist's residence; the barometer was also remark- 

 ably high, the mean 29-9558, and the maximum exceeding that in the cor- 

 responding month in 1825, which was considered extraordinary for the 

 ' season. A rainbow seen on the 25th, about 3 P.M. On the 28th and 

 29th the wind blew strong from the S.W. and W., but could not be con- 

 sidered as violent gales. The evaporation 0-125 of an inch. 



November. Thirteen days of the month might be denominated fine, and 

 the thermometer reached an elevation above any one in the same month 

 during the last seven years, while the mean temperature was nearly 4° 

 higher than in November last year. The barometer was generally low, and 

 the mean gave a depression greater than since 1826; the quantity of rain 

 much greater than usually falls in the month, indeed more than since 1825. 

 Lunar haloes were seen on the nights of the 25th and 27th, and a faint
