SEC. OF THE BRITISH METEOROLOGICAL SOCIETY. 
Till the Ctli of January the temperature of the air was i° below 
the average ; from the 7th to the 15th 7-/° above ; then for the next 
six days 8° below. A period of warm weather followed, extending 
to the 6th of February; the average daily excess for the 15 days 
being 8°. From the 7th of February to the 16th was cold, the 
daily defect of temperature being The next six days were in 
excess to the amount of 8° daily ; then from the 24th of February 
to the 5th of March there was a daily deficiency of bV, followed by 
a period of nine days whose daily average was 7° in excess ; this 
period was succeeded by another ending the 21st of March, of 
deficient temperature to the amoimt of 2i° daily; and from the 21st 
of March to the end of the quarter there was an excess of tempera- 
ture to the amount of 6° daily. 
The mean high day temperature in January averaged |°, and 
February 1-|° above, whilst in March it was 0°-l below, their 
respective averages. 
The mean low night temperature in January was 1° nearly, in 
February 3i°, and in March 3°, in excess of their respective averages. 
The mean temperature of the air was 0°-9 in excess in January, 
2i° in excess in February, and 1°*3 in March, as compared with 
the averages of the preceding 21 years, chiefly due to the warm 
nights in Febniary. 
The mean temperature of the dew-point was 0"'^6 below its average 
in January, 2° above in Februar}^ and 2°'9 above in March. The 
mean for the quarter was nearly 1^° in excess ; therefore the amount 
of water mixed with the air was less in January and greater in 
February and IMarch. 
The mean pressure of the atmosphere in January was 0'06 inch 
below, in February was 0-12 inch above, and in March 0-29 inch 
below their respective averages. 
The fall of rain in January was 1"9 inch, in February 0*5 inch, 
and in March 3-7 inches ; the total fall for the quarter was 6-1 
inches, being about 1 J inch above the average of the preceding 45 
years. 
The temperature of vegetation, as indicated by a thermometer 
placed on grass, was below 30° on 33 nights, and above 30° on 57 
nights. 
The mean temperature of the air at GreenAvich for the three 
months ending February, constituting the three winter months, was 
40°-4, being 2°-6 above the average of the preceding 90 years.
