Maury supposes, the monsoons are reversed trades, then the trade-wind and
monsoon region are identical. If the monsoons are found in the belt of
rains, then, the trades, upon Professor Dove's principles, pass into the
monsoon region by attraction or suction, without pressure. Either way the
theory is undeserving of consideration.

A new theory has recently been started by Mr. Thomas Dobson, and, although
it is (like all other efforts to get the _upper strata down_ to produce
condensation, or those below _up_, that they may be condensed), without
foundation, his collection of facts is brief and interesting. I copy his
article from the London, Edinburgh, and Dublin Phil. Mag., for December,
1853. It adds to the collection of facts in relation to the connection
between volcanic action and storms for the seventeenth century, made by
Dr. Webster:

The following appear to be the main facts which are available as a
basis for a theory which shall comprehend all the meteors in
question:

1st. The eruption of a submarine volcano has produced water-spouts.

"During these bursts the most vivid flashes of lightning continually
issued from the densest part of the volcano, and the volumes of smoke
rolled off in large masses of fleecy clouds, gradually expanding
themselves before the wind in a direction nearly horizontal, and
drawing up _a quantity of water-spouts_."--(Captain Tilland's
description of the upheaval of Sabrina Island in June, 1811, Phil.
Trans.)

With this significant fact may be compared the following analogous
ones:

"In the Aleutian Archipelago a new island was formed in 1795. It was
first observed _after a storm_, at a point in the sea from which a
column of smoke had been seen to rise."--(Lyell, Principles of
Geology.)

"Among the Aleutian Islands a new volcanic island appeared in the
midst of _a storm_, attended with flames and smoke. After the sea was
calm, a boat was sent from Unalaska with twenty Russian hunters, who
landed on this island on June 1st, 1814."--(Journal of Science, vol.
vii.)

"On July 24th, 1848, a submarine eruption broke out between the
mainland of Orkney and the island of Strousa. Amid thunder and
lightning, a very dense jet black cloud was seen to rise from the
sea, at a distance of five or six miles, which _traveled toward the
north-east_. On pa
