heory a fallacy--Land not hotter under the belt of
rains, nor sea materially so--Theory should be abandoned 52

CHAPTER V.

The agent, magnetism--Its character and currents--Oxygen
magnetic--Precipitation at the belt of rains occasioned by
depolarization--Storms originate in this central belt, and move
toward the poles 82

CHAPTER VI.

Course and functions of the counter-trade--Ours come from the
South Atlantic--Reason why it can not come from the Pacific--
Mistake of Mr. Redfield and Lieutenant Maury in regard to it--
All our storms originate in it--Proofs of this--State of the
weather, whether hot or cold affected by it--Proofs of this--All
our surface winds are incidents of it, and due to its conditions
and attractions--Proofs of this--Character of the different
winds--Anomalies of Mr. Blodgett accounted for--Received theory
in regard to sea and land breezes a mistaken one--Proofs of
this--Peculiar character of the N. W. wind--Identity with the
winter Mexican northers--Character of the West India hurricanes--
Of the thunder-gust--Of the tornado--Sundry particulars in
relation to the latter--Due to currents of electricity--
Proportions of winds in different localities--Examination of the
work of Professor Coffin upon that subject--Examination of
Lieutenant Maury's theory of the monsoons 92

CHAPTER VII.

Height of the counter-trade in different latitudes--Cause of the
Calms of Cancer--Influence of mountains upon the counter-trade--
Reports of Herndon and Gibbon--Focus of precipitation in the
extra-tropical belt north of its southern line--Evidences of
this--The elevation of the counter-trade above the earth varies
in the same latitude with the variations in the phenomena of the
weather--Temperature of the counter-trade--Rain dust, its origin
and indications--Volcanic ashes--How far they indicate its course
of progression--Question whether there is an eastern progression
of the body of the atmosphere above the machinery of distribution 179

CHAPTER VIII.

Important to understand the precise character of the reciprocal
action between the earth and the counter-trade--Connection
between the width and movements of the belt of inter-tropical
rains and the volume of the trades--Its peculiarities over
Africa, the Atlantic, and South
