Facts 10 be ReaeBbered.-In various parts of
the world local eirculations such as land and sea
brcezes, mountain winds and local winds are
experienced, some of which have acquired con-
siderable importance owing TO their effect upon
human interests. The Eohn Of Switzerland is
II dry, hot wind, which descends from the Swiss
Alps wind that increases in temperature rs
it dcscends on the leeward side TO lower levels
from the lofty ranges. In its descent il some
times receives an increment of temperature
of over 20o +. Coming up the windward side
it has its moisture condensed by the cold of
elevation, and retains the heat of vapor con-
densaton. AT the same time its capacity for
moisture is increased, aud as tho air deseends
to the valleys ii will be felt as dry, hot wind.
In North Greenland and along Smith Sound, "A
warm southeast wind occurs in the middle of
Winter, whose origin is similar to that of the
Fohn, the interior of Greenland being mount
ainous. The hot winds OF South Africa are
probably of the Same nature while as to the
HOr-westers Of New Zealand the analogy is abso-
luteiy complete.
