274 Meteorological Register Jot' 3 8^3-4*-5, kept at the 



lowing year. The average of the whole period is 56.52, being 

 about one degree lower than at Bourdeaux in latitude 44° 50''. 

 The range was greatest in 1822 and 1823, and nearly equal ; 

 and several degrees less in 1824 and 1825, being least in the 

 latter year. The N., N. W., W. and E. winds are most uni- 

 form in the several years ; the rest are more variable. The 

 prevailing winds are S. W., N. W., and S. E. The propor- 

 tion of fair weather was greatest in 1822, and least in 1823, 

 which, however, differed but little from 1825. The proportion 

 of cloudy weather, rain, and snow, is pretty equal, except that 

 there was much less snow in 1822. The aggregate mean for 

 the whole period was, fair 17.46, cloudy 5.47, rain 6.10, 

 snow 1.36. 



" In 1822 the mean temperature at the east and west was 

 nearly equal. In 1823, 1.74 lower at the east, and but 0.33 

 lower at the west, than in the previous year ; the winter being 

 comparatively milder at the west. In 1 824, the mean tempe- 

 rature was again nearly the same, but about one degree lower 

 than in 1822. In 1825, it was higher than in any previous 

 year, and 1 .88 higher at the west than at the east. The ave- 

 rage for the four years was 46.83 and 47.74, being 0.91 high- 

 er at the west. In 1822 the range was 40° greater at the 

 west; in 1823 it was 32° greater; in 1824, 19°; and in 1825, 

 25°. The greatest proportion of fair weather, both at the east 

 and west, was in 1822 ; with rather the most at the west. In 

 1823 there was much less at the east, and somewhat less at 

 the west, than in the former year. In 1824, there was rather 

 more at the east, and about the same at the west as in 1823 ; 

 and in 1825 it was about the same at the east, and consider- 

 ably less at the west, than in the previous year. The propor- 

 tion of rain was nearly the same at the east during the four 

 years, but somewhat less in 1825. There was a great differ- 

 ence at the west, being much greater in 1825, than in any 

 other year, and much less in 1823. The proportion of snow 

 was much the greatest at the east in 1 823, and least in 1822 ; 

 at the west it was greatest in 1822 and 1824, and least in 

 1825. The average for the four years was, fair 16.64 and 

 18.11, cloudy 8.86 and 6.44, rain 4.12 and 4.04, snow 0.78 

 and 2.05 ; being rather more fair, and less cloudy weather.
