of the barometer at Greenwich was 29 '624 inches, and was 0*125 
lower than the mean reading for the corresponding period of 45 
years ; the mean reading was below the average in October and 
December, while in November it was above the average. 
The weather in October during the first 12 days, and from the 
19th was warm, particularly during the first week; the tempera- 
ture at the Eoyal Observatory, Greenwich, rising to 79° -2 on the 
4th, a point higher than in any October back to 1859, when it was 
SI"* 1, and to 77° on the 5th ; the mean temperature of the 4th and 
5th days was more than 10° above the average. The month was 
warmer than any October back to 1861. The fall of rain was 
above its average at most stations. The atmospheric pressure was 
above its average till the 8th and from the 21st, and below from 
the 9th to the 20th, particularly so on the 15th, 16th, and 17th 
days. 
The weather in November was generally unsettled ; the tem- 
perature was variable, being for a few days together above the 
average, and then for a few days together below. The atmospheric 
pressure was generally below its average till the 17th, and 
generally above from the 18th. The fall of rain was generally 
less than the average ; about London it was a little in excess of 
average ; it fell frequently tiU the 20th day. The wind was mostly 
from the S.AV. ; the latter part of the month was cloudy, foggy, 
and dull. 
The weather in December was for the most part dull and cold, 
and very exceptional ; the temperature in the first week was very 
low ; on the 2nd day it was more than 10° below its average, and 
on the 3rd -day was nearly 14° below its average ; from the 6 th to 
the 15th it was mostly mild, and very cold from the 16th to the 
end of the month, particularly so on the 18th, 19th, 20th, and 21st ; 
the mean temperature of these four days was 27°, or 12|° below 
their average. The atmospheric pressure was very remarkable ; 
till the 5th day it was a little in excess of its average, and then 
nearly constantly below till the 29th day, and particularly so on 
the 8th and 9th, whose average daily pressure was nearly 1 • 4 inch 
below their averages. The low readings of the barometer on the 
8th and 9th were very extraordinary: at Blackheath on the 8th 
the reading was nearly stationary from 8 p.m. to near midnight at 
28*157 inches; it then rose to 28-16 inches by 2 a.m. on the 9th, 
and then decreased to 28-14 inches by 7 a.m., a point lower than 
any reading since 1843, on January 13th, when it was 28*096 
inches. Eain fell on five days out of six at southern stations, and 
was above its average at all stations; on the 26th rain fell at
