156 Meteorological Summat-y for 1822. — Hampshire. 



thermoiiietrical observations. Tlie mean temperature of Ma}', 

 too, was higher than the- mean of September, which is also 

 unusual : it was the means of the most early hay-niaking, and 

 of the earliest completion of an abundant corn harvest, we can 

 remember : in short, it brought on an early and dry summer 

 that was almost equal in its monthly mean temperature. 



The annual mean temperature of the air at 8 o'clock A.M. 

 and 8 P.M. coincide within J-th of a degree; but they deviate 

 from the mean of the extremes nearly 1 1°. The annual mean 

 temperature o^spring water as taken at 8 A.M. is nearly a 

 degree less thaiK|lie annual mean temperature of the air : last 

 year it was rather more than a degree minus. 



The maximum temperature of the ground, as inferred from 

 the temperature of spring water, took place at the latter end of 

 September, a fortnight sooner than in 1821. 



The mean state of the air, by De Luc's whalebone hygro- 

 meter, is 5°*8 drier than tlie preceding year, and y^ths of a 

 degree drier than that of the dry year 1820. After so dry an 

 air, the two very wet autumnal months, October and Novem- 

 ber, which afforded almost the one-half of the year's depth of 

 rain, was most powerfully felt by the human constitution, in 

 the attacks of acute rheumatism and asthma. 



Wind. — There is a near coincidence in the position and 

 duration of the reigning wuids this and the preceding year ; 

 the South- West having prevailed longer, and the North shorter, 

 than from the other points of the compass. The next greatest 

 durations are in the North-East and North- West winds. The 

 remarks on the winds in our annual meteorological results for 

 1821, in vol. lix. pages 276 and 277 of the Philosophical Ma- 

 gazine and Journal, still hold good, and they supersede the 

 necessity of further explanations thereon at present. The fol- 

 lowing is the ninnber of strong gales of wind, or days on which 

 they have prevailed this year, namely : 



Clouds. — Of these we have only to remark that the cirrus, 

 cirrocumulus, and cirrostratus, have been more prevalent, and 

 the stratus and 7iimbus less in ajipearance than in former years, 

 when a similar quantity of rain has fallen. There has not 

 been so great a display of atmospheric liliccnomena this year as 

 last, excepting lightning, thunder, and meteors. — With regard 

 to the meteors, almost one-half of the anruial number was seen in 



August :
