الصفحة 15 - He then goes on to say — but it by no means follows that this must always be the case : In general, a rapid transfer, either way in latitude, of any mass of air which local or temporary causes might carry above the immediate reach of the friction of the earth's surface would give a fearful exaggeration to its velocity.
الصفحة 94 - York.—The first half of a revolving gale is a fair wind from Bermuda to New York, because in it the wind blows from the east; but the last half is a fair wind from New York to Bermuda. During the Winter season, most of the gales which pass along the coast of North America are Revolving Gales.

الصفحة 13 - He farther inclines to believe that "as the external motion is imparted to the interior motion of the mass, and centrifugal action begins to withdraw the air from the centre and form an up-current the whole will soon be involved in the same vortical action." The up-current he explains as being formed by the pressure being removed from the centre, when the air there " increases in bulk, diminishes in specific gravity, and its upward tendency follows as a matter of course.
الصفحة 203 - It came on very swift, and broke a little before it reached the ship, making a great noise, and raising the sea round it, as if a great house, or some such thing, had been cast into the sea. The fury of the wind still lasted, and took the ship on the starboard bow with such violence, that it snapt off the boltsprit and foremast both at once, and blew the ship all along, ready to overset it ; but the ship did presently right again, and the wind whirling round, took the ship a second time with the...
