its temperature sinks, and, on account of the greater specific caloric,
it imparts a much higher temperature to those layers than is due to
their position; an elevation consequently takes place,--begetting a
drain from below, until the upper regions are loaded with a warm and
vapory atmosphere. If the action of the sun conspires at the same time
to increase the effect, the storm will be more violent. In twelve hours
after the meridian passage of the vortex, the storm is brought under the
parts of the ethereal atmosphere of the earth most remote from the axis;
a reaction now takes place; the cold ether of space rushes in, and, on
account of its great specific caloric, it abstracts from the warm
atmosphere more than pertains to the difference of temperature, and
there is a great condensation. Rain and hail may form in fearful
quantities; and when the equilibrium is restored, the temperature will
have fallen many degrees.

As it is important that we should have a clear view of the character of
the ether, we will revert to the principle we have advocated, viz.: that
in equal spaces there are equal momenta. What the ether wants in
inertia, is made up by its motion or specific heat, considering in this
case inertia to stand for weight when compared with ponderable matter;
so that to raise an equivalent amount of inertia of ether to the same
temperature as atmospheric air, will require as much more motion or
specific heat as its matter is less. And this we conceive to be a law of
space in relation to all free or gaseous matter. To apply it to solids
would require a knowledge of the amount of force constituting the
cohesion of the solid.
