THE PLANES OF NATURE.

Ik order to enunciate even these broad principles,
however, it is necessary to begin by explaining
some of the facts discovered by the use of
this very faculty. The first point which must
be clearly comprehended is the wonderful com-
plexity of the world around us—the fact that
it includes enormously more than comes within
the range of ordinary vision.

We are all aware that matter exists in
different conditions, and that it may be made
to change its conditions by variation of pressure
and temperature. We have the three well
known states of matter, the solid, the liquid and
the gaseous, and it is the theory of science that
all substances can, under proper variation of
temperature and pressure, exist in all these
conditions. There are still, I think, a few
substances which chemists have not succeeded
in reducing from one state to another; but it
is universally believed that just as water may
