November. 
Great and sudden changes of barometric pressure occurred 
during this month. Cyclonic systems from the Atlantic, 
accompanied by strong South-Westerly winds and mild 
weather, appeared with considerable frequency. The rainfall 
was in excess of the average, the fall on the 18th (0'97 ins.) 
being the heaviest day’s fall for the year. The latter part of 
the month was colder, but frost was slight, and many garden 
flowers remained in bloom till a much later period than 
usual, and it was not until the morning of the 22nd that the 
dahlias were destroyed. An illustration of the mildness of 
the season was a display of dahlias grown in the open, 
exhibited at the Norwich Chrysanthemum Show on Novem- 
ber 16th. 
December. 
This month was unseasonably mild, stormy, and humid, 
and was the third wet December in succession, although the 
total rainfall (3‘98 ins.) was less than in the two previous 
years. A remarkable feature was the persistency of the rain, 
there having been only two days during the month on which 
rain was not registered. At Dilharn, Norfolk, rain was 
recorded on all the 31 days of the month. Christmas was 
again snowless, and it is now 21 years since we had a 
Christmas Day with snow lying on the ground, although a 
deep snow occurred on Boxing Da) r in 1906.
