November. — This month was mild for the period of the season, 

 the mean temperature being upwards of 4° above the average. A 

 most unusual quantity of rain fell. On the 11th more than an 

 inch, and again on the 14th about an inch and a quarter depth of 

 rain was measured. The tide in the Thames at Chiswick was 

 four inches higher than it had been known for fifty years. 

 Within this period the highest tide was noted to have occurred 

 on the 28th of December, 1821, but it has been exceeded by that 

 of the 12th of the present month. 



December. — The wind was from south-west and south for 

 twenty-eight days, and, owing to this, the temperature was 

 remarkably high for the period of the season. The mean 

 temperature was higher than in any December since 1806 ; 

 it was higher than that of last October ; the nights were fully 10° 

 warmer than those of April of the present year, and within a 

 degree of being as warm as those of May. The minimum was 

 fully 6i° above the average minimum for December. The quantity 

 of rain was about half an inch above the average, and completed 

 the unusual amount of fully thirty-two inches and a half for the 

 year. The 16th was clear and boisterous, with lightning. The 

 26th and 27th were also very boisterous.
