Rain fell on 13 days, to the total depth of 274 inches (equivalent 

 to about I2| gallons of water to the square yard). Heaviest fall on 

 any day 0*56 inch, on the 1st. 



The prevailing winds were south-westerly and north-easterly. 



The average velocity of the wind was 5 miles an hour. 



There were 129 hours of bright sunshine, equal to 40 per cent, of 

 the greatest possible amount. 



There were 6 days on which no sunshine was recorded. 



November. — Throughout this month the weather was of a very 

 changeable character, although until near its close there were no serious 

 gales or other phenomena of special note. Probably the most out- 

 standing feature of the weather was the unusually high temperature 

 for November which was experienced over all the western parts of the 

 Kingdom at the beginning of the second week, when maxima approach-

 co. Wicklow, whilst further to the east the temperature varied but 

 slightly from the normal. No really severe weather occurred until 

 the commencement of the last week, when a severe southerly gale 

 swept the whole Kingdom, bringing with it heavy rain, and over the 

 northern counties deep snow, followed everywhere by a sharp fall of 

 temperature and severe ground frosts. At Wisley the thermometer 

 on the grass fell to 19 0 , but over the north of England readings io° 

 lower than that were general. Rain fell frequently throughout the 

 month, but as a rule the falls were slight and in most districts the 

 monthly totals were a good deal lower than the average. The record 

 of bright sunshine was also very low generally, the most favoured 

 region being the east of Scotland ; but many parts of the country 

 which usually are the most sunny had less than 20 per cent, of their 

 possible amount — Jersey received only 16 per cent, and Wisley but
