Ider than that of the east. Altitude exerts a considerable in- 
lonce upon temperature ; and though considerable variations

lur down upon the western parts of the kingdom much more 
in than falls on the eastern side. In the west, a greater quan- 
V also falls in autumn and winter than in summer, while in 
(■ east this is reversed. The minimum average annual rainfall 
I the western side of England is about 32 inches in the lower 
stricts, and the maximum 146 inches on the mountains. And 
pre are wet days in a year amounting to a minimum of 135 
r the lower grounds, and a maximum of 250 on the hills. On 
p eastern side of England, the minimum annual rainfall is 
tout 20 inches, and the maximum 33 inches ; the number of 
■t days in a year being about 115 in the driest up to 185 in the 
^ttest localities. (See Table, page 11.) 
The hygrometric condition of the atmosphere in the western Atmospheric 
id eastern parts of England does not vary so much as might be moisture, 
pected. Thus the evaporation from a sheet of water amounts 
21"5 inches in a year on the western side, and 26'7 inches on 
e eastern side of the kingdom. The quantity ranges from 0*4 
ch in December, and a like amount in January, up to 4*2 
ches in June- — the evaporation in each month being somewhat 
eater in the eastern than in the western counties. The dew- 
)int in January is in the north-west 31 degrees, in the south- 
est 40 degrees, in the north-east 30 degrees, and in the north- 
)rth-east 31 degrees. In August it is 52 degrees in the north- 
est, 58 degrees in the south-west, 51 degrees in the north-east, 
id 56 degrees in the south-east. 
The prevailing winds blowing over England for two-thirds of Prov.illing 
e year, are from points varying between south and north-west, wiu-ls.
