January. — The winter has been remarkably mild ; no snow, 

 and only a few showers of hail and sleet, which were dissolved 

 as fast as they fell. The last 24 days of this month, the barometer 

 stood uniformly (one day excepted) above 30 inches. If the 

 addition for the elevation of the barometer was made, the last 

 27 days of the month, the mercury stood above 30 inches. 



February and March. — These months also were remarkably 

 mild. Only one day on which we had any frost.

 showers.

 sively hot for this season of the year.

November. — Several days in this month particularly rough ; 

 blowing very strong on the 23d, 24th, 25th, and 28th. The lat- 

 ter day was attended with very sudden squalls, raging to aperfect

 violence. On the evening of this day, there was a very beautiful 

 lunar rainbow. 



December. — Generally speaking very mild. A few days sharp 

 frost, with gentle wind : 23 days of this month, making the
