A COMPARISON BETWEEN THE CLIMATES OF GREAT 

 MALVERN AND LONDON. 



In the following statement, the details of the climate of London 

 are taken from the Meteorological Tables of the Royal Society, as 

 published in the *' Athenseum j" those of Malvern have already 

 appeared in the first and succeeding numbers of "The Analyst," 

 excepting the observations upon the hygrometer, and the tempera- 

 ture of the mercurial column of the barometer, with some other 

 minor details which we have subsequently procured. 



On the present occasion we shall confine ourselves to the 

 summer and autumnal quarters of 1834 ; the former including the 

 months of June, July, and August j the latter, September, Octo- 

 ber, and November. 



TEMPERATURE. 



In the month of June, the first month of the summer 

 quarter, the mean temperature of Malvern was 3.8° lower 

 than the mean temperature of London. The mean maxi- 

 mum at Malvern was 66.8° the mean minimum 51.0.° In 

 London the mean maximum was 7'2.5,° the mean minimum 

 65 ° The greatest height of the thermometer during the 

 month was, in London, 86.7° in Malvern, 76° j the mini- 

 mum, in the former place, 47.3° in the latter, 43.° The 

 greatest range during the month, for London, 39.4° for 

 Malvern, 33.° 



In July, the second month of the summer quarter, the 

 mean temperature at Malvern was 6.5° lower than the 

 mean temperature in London. The mean maximum at 

 Malvern was 67,° and the mean minimum 54.1.° The 

 mean maximum in London, 74.7° the mean minimum 

 59.3 ° In London the maximum height of the thermome- 

 ter was 86.7° i» Malvern, 80° 3 the minimum, in London, 

 51.4,° in Malvern, 49.5.° The greatest range, in London, 

 35.3 ° in Malvern, 30.5.° 



In August, the last month of the summer quarter, the 

 mean temperature of Malvern was 5.3° lower than the 

 mean temperature of London. The mean maximum at 

 Malvern, 6*6.5.° the mean minimum 53.6.° The mean 

 maximum in London, 72.8,° the mean minimum 57.9.° The 

 greatest height of the thermometer during the month, was, 

 in London, 83.3°; at Malvern, 75.5 : the lowest, in Lon- 

 don, 46.2° 3 at Malvern, 43.° The maximum range in the 

 former place 37.1,° in the latter 32.5.° 



Thus we get for the summer quarter —
