their supply of
rain is not large and much of it falls in showers. The same is true of the
Barbary States, of Syria, and Persia, and of Southern Europe; and indeed
of all the countries of the globe which lie between the winter and summer
extreme limits of the surface-trades, and without the limits of the two
concentrated counter-trades. Enough appears in the writings of the
meteorologists of Europe to show, that their long continued rains, which
are analogous to our storms and are _preceded by the formation of the true
cirrus of the counter-trade_, follow the same great law of curvature and
progress; although the presence of the Gulf Stream with its mass of south
polar waters on the western side of the British Islands, Denmark, and
Norway supplies them with showers, and fogs, and cumuli from the west and
north-west, and makes the mean of the surface winds of their storms
somewhat variant from ours. A like law reversed prevails in the southern
hemisphere. The storms of New Holland and the Indian Ocean, south of the
limits of the trade, curve to the eastward and travel about south-east,
their _south-west_ being a _clearing off wind_ as our _north-west_ is, and
_precisely similar in all its other characteristics_, where the relation
of magnetic intensity is the same.

The storms of the Pacific on the S. W. coast of South America, in like
manner travel to the S. E., flooding the western slopes of the mountain
ranges with rain, and aggravated by the intensity of the magnetic currents
at the extremity of the continent in a high latitude, meet the mariner in
the face as he emerges from under the lee of the land and attempts to pass
the Horn. It will ultimately be shown that the precipitation which takes
place, as the storms and counter-trades pass north and east in the
northern hemisphere and south and east in the southern hemisphere, is
owing less to cold than increased magnetic intensity. And all this is the
result of one great uniform law, existing every where, varying in its
phenomena only in consequence of the difference in volume, and
magneto-electric intensity of the portions of the counter-trade, as of the
surface-trade at different places, and the different magnetic intensity of
the local perpendicular and circular currents of the earth over which they
pass, at different periods and at different points.

Mr. Redfield and Lieutenant Maury have assumed that our S. W. current
comes from the Pacific Ocean. Aside from the
