y are able to register the heat waves
of a candle at the distance of one mile; while others are able to record
the presence of certain chemical elements in the most distant of the
visible stars, by means of the light waves carrying certain forms of
vibration.

Sensing the Higher Vibrations.

Under the radio-active theory it is quite reasonable to conceive of the
clairvoyant sense being able to register and interpreting these higher
vibrations which are beyond the power of even the most delicate
instruments of science. It must be admitted that the existence of such
vibrations being granted--and science tacitly admits their
presence--then ordinary distances on earth would be no barrier at all to
the action of clairvoyant vision capable of registering them. Moreover,
in such case all intervening objects would be penetrated by these waves,
and as a writer has well said, "they would be able to cross one another
to infinity in all directions without entanglement, precisely as the
vibrations of ordinary light do." Physical science and psychic science
at last seem to have arrived at a common ground of understanding, and
many of the most advanced scientists do not hesitate to admit this
fact, though their more conservative brethren hesitate to do so.

Viewing Distant Scenes.

A writer has said of this form of clairvoyant perception: "The view of a
distant scene obtained in this way is in many ways not unlike that seen
through a telescope. Human figures usually appear very small, like those
upon a distant stage, but in spite of their diminutive size they are
clear as though they were close by. Sometimes it is possible by this
means to hear what is said as well as to see what is done; but as in the
majority of cases this does not happen, we must consider it rather as
the manifestation of an additional power than as a necessary corollary
of the faculty of sight. It will be observed that in cases of this kind
the clairvoyant does not actually leave his physical body at all--he
simply manufactures for himself, and uses, a kind of psychic telescope.
Consequently he has the use of his physical powers while he is examining
the distant scene; for example, his voice usually describes what he sees
even while he is in the act of making the observation."

Time Clairvoyance.

In what is called Time Clairvoyance the clairvoyant is able to perceive
objects, persons, scenes, and events removed from him in past time or
future time. T
