By the conjoint labours of Mr. Redfield, Colonel Reid, and Mr.
Piddington, on the origin and nature of hurricanes, typhoons, or
revolving storms, the following important results have been obtained.
Their existence in moderate latitudes on both sides the equator; their
absence in the immediate neighbourhood of the equatorial regions; and
the fact, that while in the northern latitudes these storms revolve
in a direction contrary to the hands of a watch the face of which is
placed upwards, in the southern latitudes they rotate in the opposite
direction,--are shown to be so many additions to the long chain of
evidence by which the rotation of the earth as a physical fact is
demonstrated.
