ON 
THE METEOEOLOGY OF ENGLAND 
DURING 
THE QUARTER ENDING MARCH 31, 1863. 
By JAMES G L A I S H E E, Esq., F.E.S., 
EEC. OF THE BBJTISH METEOROLOGICAL EOCIETT. 
With the exception of the period between March 9th and 19th, 
when the temperature was below the average to the amount of 2^" 
daily, the weather was warm throughout the quarter, averaging 
a daily excess of 41° for the remaining 79 days. 
The mean temperature of the 3 months was 42°-6 ; in 1834 it 
was 42°-9 ; in 1846 it was 43^-6; and these are the only instances, 
BO far as trustworthy records extend, of an excess over the tem- 
perature of the first three months of the present year. The mean 
temperature of January was 41|°; of February, 42°-l ; of Maich, 
43°-9. 
The mean high day temperature was in excess 3°"8, 4°*6, and 
3°-7 respectively in the three months. The mean low night tem- 
perature was in excess 3°'2, 2°'2, and 0"*2 respectively. Therefore 
both days and nights were warm in January and Eebniary ; in 
March the days were warm, and the nights about their average. 
The mean temperature of the air in January was 5°'2, in February 
3°'6, and in March 2°-6, above the average of 43 years. 
The temperature of the dew-point in January, February, and 
March respectively was 2°'4, 3°-2, and 0°"9, above the averagfe of 
the preceding 22 years. 
The pressure of the atmosphere was in defect in January and 
March, and in excess in February. 
The fall of rain in the south of England in January was somewhat 
in defect, a little over its average about London, and very much in 
excess in the north. All over the country February and March 
were remarkably fine and mild. 
The mean temperature of the air at Greenwich in the three 
months ending February, constituting the tliree winter months, was 
42°-5, being 4°-7 above the average of the preceding 91 years.
