Thirdly, the neighbourhood of mountains seems to increase 
the absolute variability, particularly in the summer months. 
Fourthly, on passing from the coast into the interior of con- 
tinents, the absolute variability, which, in a sea climate, is 
small, gradually increases, but then decreases as we advance still 
further inland: the greatest absolute variability is therefore nei- 
ther in the true sea climate, nor in the thorough continental 
climate, but rather at the point where they pass into each other, 
as seen in the following table :—

Fifthly, the month of September is the steadiest, particularly 
in the region of the summer rains in the temperate zone. The 
variability is greatest in the winter months, and decreases rapidly 
towards spring, in which, at many places, it reaches its minimum. 
_ When we consider that the differences of the yearly means in 
our latitude are 2}° or 34°, and in the winter months may be as
