By JAMES G L A I S H E E, Esq., F.E.S., 



SEC. OF THE BRITISH METEOROLOGICAL EOCIETT. 



The temperature of the air differed little from its average value 

 during the quarter. 



The periods and average daily amounts of excess were January 

 1st to 4th, 71° ; January 9th to 20th, 3i° ; February 6th to 24th, 3^° ; 

 February 27th to March 7th, 3°; March 14th to 20th, 5°; and 

 March 28th to the end of the month, 4^°. 



The periods and average daily amounts of defect were January 

 5th to 8th, 3^° ; January 21st to Febraary 5th, 6i°; February 25th 

 and 26th, 3i°; March 8th to the 13th, 4f°; and March 21st to the 

 27th, 4°. 



The pressure of the atmosphere was in excess in Februarj^ and in 

 defect in the other two months of the quarter. It was from 0*2 

 inch to 0'3 inch greater in February than in the preceding month, 

 and from 0*1 inch to 0*2 inch less in March than in February. 



The degree of humidity was a little in excess upon the quarter. 



The daily ranges of temperature were in excess in January and 

 February, particularly in the latter month, and of their average 

 values in March. 



Eain was slightly in excess in January, and in defect in February 

 and March, particularly in the former month, so small a quantity 

 not having fallen in any February since the year 1821, and was in 

 defect to the amount of 1^ inches upon the quarter. 



The quarter was remarkable for the storms of snow and hail 

 experienced in March, the hail-balls being large in size and pyra- 

 midal in shape. 



Also for the very large barometer ranges ; each month exceeding 

 1 inch ; and for March in the South of England the range was about 

 li inch; increasing up the country, till at the farther extremity it 

 was nearly 2 inches. 



The mean temperature of the air at Greenwich for the quarter 

 ending February, constituting the three winter months, was 38 '7°, 

 being 1"0^ above the average of 86 years.
