ON 
THE METEOROLOGY OF ENGLAND 
DURING 
THE QUARTER ENDING DECEMBER 3], 1860. 
By JAMES GLAISHEE, Esq., F.E.S., 
8EC. OF THE BRITISH METEOBOLOGICAI, SOCIETY. 
With the exception of the last ten clays in October, and the first 
ten daj.s in December, the weather has been cold throughout the 
quarter. The deficiency of temperature was large about the 12th 
of October, was about 3° below the daily average in November, and 
was very large from the 18th to the 29th of December, the cold 
having been singularly severe between these days, exhibiting a great 
•contrast to the weather at the beginning of the month. On De- 
cember 5th and 6th the excess of temperature above the average 
was 9°; from the 18th to the 23rd it was each day from 7° to 10° 
below; as nuich as 15° on the 24th; 1G° on the 25th; and 14° on 
the 29th. On the 7th day the temperature in the neighbourhood 
was as high as 54°, and on the 25th and 29th was as low as 7° and 8°. 
These latter temperatures are very remarkable for December. In 
the year 1846 the mean temperature of December was 32^"9, being 
3°*4 lower than in the month just passed. In the year 1852 it was 
47°'6, or 11*^-3 warmer than in 18G0. Tliis was the hottest December 
in the last 20 years. 
The mean temperature of October was 1° above, of November 
was 2^2 below, and of December was 4° below their averages as 
-found from Ihe observations of the preceding 19 years. 
The pressure of the atmosphere was slightly above Its average in 
October, and below in November and December, being smaller in 
December than in any December for 20 years. 
The fall of rain was slightly deficient in the quaiier, and amounted 
to 32 in. in the year. This was exceeded in the years 1821, 1824, 
and 1852; but is greater than in all other years since the year 
1815. 
The mean temperature of the air at Greenwich for the three 
months ending November, constituting the three autumn months, 
was 48-*3, being 1°-1 below the average of the preceding 89 years.
