Glaisher states, that at Greenwich the mean barometric pressure 
for September has only twice in the last thirty- five years averaged 
so low as in this year. 
October. 
The mean temperature of this month exceeded the average of 
the last six years by 4.8 degrees, and was the mildest October 
recorded in that period ; the excess occurred chiefly in the 
night temperatures, which were 7 degrees above the average ; the 
day temperatures were only 3.4 in excess. Mr. Glaisher states, 
that at Greenwich, the mean temperature of October has only been 
exceeded eight times in the last hundred years. The unusually 
high temperature of 71.8 was recorded on the 7th, and the lowest 
during the month was only 30.0. The month commenced with a 
strong X. wind on the 1st, with a quick rise in the barometer from 
29.740 at 9 a.m. to 30.161 at 9 p.m. The weather was unusually 
mild until the 19th, but the sky was generally overcast ; several 
showers of drizzling rain were recorded; the winds were mostly 
light from the S. until the 15th, and from the E. from the 16th to 
the 19th. Frequent variation in the barometer was recorded, but 
no unusual oscillation occurred ; the readings were generally below 
the average. From the 20th of October until the end of the month 
the days were much colder, the highest temperature being only 
55.0. The sky was very overcast ; the winds variable, blowing 
strong from the N.E. and E.X.E. on the 21st and 22nd, and from 
the W.N.'YV. on the 31st. The barometric pressure from the 20th 
to the 31st was high and very steady, all the readings being above 
30 in. The rainfall was the smallest amount recorded in October 
since 1861 ; it was 2.09 in. below the average of the last thirty- 
live years. 
November. 
This month was unusually dull and gloomy, but mild (except 
from the 7th to the 13th), the mean temperature being about 
2 degrees above the usual average. Rain fell on 22 days, but 
the showers were mostly very slight, and the total fall exceeded 
the average by only 0.38 in. The first six days were mild and 
showery, with light variable winds, sky generally overcast, and
