here, certainly, there must be evidence
of the truth of the rarefaction theory, if any where on the face of the
earth. Yet here, in July and August, we find the trades as regular as any
where, and not more variable winds than are found in the trades toward
their northern limits every where, and in August, only forty out of four
hundred and twenty-nine winds, blowing directly or indirectly on shore.

It would seem to be impossible for any man to believe in the theory of
rarefaction, after an examination of these tables.

Professor Coffin discovers other anomalies, for which he finds it
difficult to account. Among these are the northerly tendency, in the
afternoon, of the winds in Ohio, south of Lake Erie; the winds of
south-western Asia, which, he says, "Are so irregular as to defy all
attempts to reduce them to system;" particularizing the N. W. at
Jerusalem, the westerly at Bagdad, the N. E. at Constantinople, the
northerly at Trebizond, etc., etc. Jerusalem has the Mediterranean at the
N. W., Bagdad has it at the west, Constantinople has the Black Sea at the
N. E., Trebizond N. N. W. and N. E., and the counter-trade, as it passes
over them, draws its storm-surface wind or sea-breeze, from the quarter
where evaporation is greatest, and the atmosphere is most susceptible of
electrical inductive influence. Precisely as it draws from the ocean and
the eastward, east of the Alleghanies, from the lake region, west of the
lakes, and from the northward, south of the lakes, and from the westward,
east of them.

This law of attraction will explain, too, the mean prevalence of easterly
winds north o
