on the same day, both at Geneva and throughout all Scotland *. 

 At the same time, a corresponding fall of the barometer was also 

 observed at London f. During the latter part of November and 

 the first three weeks of December 1821, Carlisle was visited by 

 several violent hurricanes, accompanied with heavy showers of 

 hail, and torrents of rain. On the 1 8th of December, there was a 

 dreadful thunder-storm, and extremely vivid lightning, followed 

 by hail and rain. On the 20th, a violent hurricane, with heavy 

 rain in the night. During the three or four following days, there 

 were several showers of hail and rain, and snow upon the neigh- 

 bouring mountains. On the 25th, the day on which the great- 

 est depression of the barometer occurred, the weather was fair 

 and pleasant, and continued fair, mild and pleasant until the end 

 of the month. The average of the barometric pressure of tliis 

 month, 29,321, is the lowest monthly average in the journals. 

 The average temperature of the month, 42, 1, is higher than the 

 December average of any other year, excepting December 1806, 

 when it was 43,5. The average height of the barometer of 

 December 1806, was 29,377, which is the next lowest average 

 for December. The barometer also sunk so low as 28,48 in De- 

 cember of this year ; and there was great similarity of weather 

 during the month, a violent storm of thunder, lightning, hurri- 

 canes, and showers of hail and rain. The minimum of the ba- 

 rometer occurred on the 2d of December, wind north-west. 

 During the thunder-storm which took place on the 13th, the ba- 

 rometer stood at 28,55, wind south. In the intervening days, 

 the mercury was comparatively low. In 1821, the thermometer 

 ranged from 55 to 30, in the month of December, and the ba- 

 rometer from 30,23 to 28,26. In December 1806, the range of 

 the thermometer was from 54 to 26, and of the barometer from 

 30,48 to 28,48.
