phantasms of the living, phantasms of the dying, and phantasms
of the dead--according to whether the subject is yet living, is dying,
or has recently died. In all such cases we may postulate a telepathic
action at the moment of death, for in those cases when the apparition
was seen but a few minutes or even a few hours after death, the impact
might have been transmitted at the moment of death, and only have
emerged into consciousness during the quietness and peace of the
evening, or when night gave it a chance to do so. For we now know that
subconscious ideas do tend to rise into consciousness when the latter is
less occupied with the events of the day.

It is, of course, impossible to detail here the mass of evidence of all
kinds which has been accumulated of late years in favour of the
existence of telepathy, but enough has been quoted to indicate the
method of approach and the character of the evidence adduced. Suffice it
to say that, in the eyes of those who have inquired into the subject
closely, telepathy is now held to be proved; it is now considered to be
a scientific fact, though not as yet explained. Again I repeat, the
question is not: Is it possible? but, Is it a fact?

Taking all that has been said into consideration, it may fairly be
contended that the mere _fact_ of telepathy may therefore be said to
have been proved. This being so, the interesting question of its nature
or character presents itself. How is such action to be explained? How
account for the facts?

There are many theories which have been advanced from time to time to
explain this remarkable phenomenon, and, if it be a fact in nature, its
scientific explanation must some day be forthcoming. Once telepathy
stands proved it will mean the remoulding and recasting of many of our
scientific theories, and even a reconstruction of science--in so far, at
least, as it refers to physiological psychology. Such being the case,
and telepathy being proved, as many eminent men of science today
believe, the question of its theoretical explanation becomes most
important.

Now the first analogy which strikes one in the consideration of this
question is that of wireless telegraphy--the subtle electric vibrations
which journey to and fro with incredible swiftness through the universal
ether. In short, telepathy is thought by many to be simply a species of
physical vibration, proceeding from brain to brain, just as electric
waves pass from the transmitter t
