being great. The air was unusually dry, and the sky was very 
bright. The duration of sunshine was unusually great, averaging 
an hour and 34 minutes a day in excess of the mean. The rainfall 
was small, the number of rainy days being exceptionally so in 
comparison with the amount of rain. Westerly winds prevailed, 
easterly and south-westerly being the next in frequency. 
The Autumn (Sept, to Nov.) was of about average temperature, 
though the nights were colder and the days warmer than usual, 
the mean daily range being rather great. The air was of average 
humidity, and the sky was of about average brightness. The 
duration of sunshine averaged about 7 minutes a day less than 
usual. The rainfall was exceptionally small, and so also was the 
number of wet days. The prevailing direction of the wind was 
westerly, the next most frequent winds being south-westerly.

January.— A rather mild month, of average humidity and 
cloudiness, with a very small rainfall on nearly the average number 
of days. Both the mean minimum and the mean maximum 
temperatures were a degree above the average. There was the 
usual duration of sunshine; rather less than two hours a day. 
The prevailing direction of the wind was westerly. The first nine 
days and the last four were rather cold, and it was during these 
periods only that any snow fell; in the earlier period on the 
6th, 7th, and 8th, and during the later on the 26th and 27th, 
with hail, and on the 31st. Mr. Mawley remarks that the 27th 
was the most windy day but one which he has ever recorded at 
Berkhamsted in any month, the force of the wind from 9 a.m. until
