The preceding remarks are probably sufficient for their principal
purpose--these pages may fall into the hands of persons familiar with
the subject, to whom the following observations may be addressed, as
some of the _reasons_ for what has been so briefly, if not too
positively outlined. As the mercurial column rises with increase of
pressure by the atmosphere, and descends when the pressure diminishes,
it indicates a greater or less accumulation of air, which, like other
fluid, such as water (when heaped above its average level or reduced
below it, from whatever cause),--will have a tendency to fall or rise
till the general equilibrium is restored.
