or to their
influence, as all students of this subject know. If you have been, or
are fearful of the psychic influence of any person, you must get to work
and drive out that feeling by positive and vigorous denials. The DENIAL,
as all students know, is the positive neutralizer of the psychic
influence of another person, providing you make it in full belief in its
truth. You must take the mental position (which is really the true one)
that you are absolutely immune to the psychic attack or influence. You
should say, mentally, 'deny to any person the power to influence me
psychically without my consent; I am positive to all such influences,
and they are negative to me; I neutralize all such influences by this
positive denial!' It should encourage you to know that it requires far
less force and power to repel and neutralize psychic influences of this
kind, than is required to send forth the power; an ounce of denial and
protection overcomes a pound of psychic attacking power. Nature gives
you the means of protection, and gives you the 'best end of the stick';
and it is your own fault if you do not use it effectively. A word to the
wise is sufficient."

Telepathic Phenomena.

The second general class of phenomena in the general category of
Voluntary Transmission of Mental Vibrations is that known as "Telepathic
Phenomena." In a sense, of course, all phases of Thought Transmission,
and particularly that of Voluntary Thought Transmission, may be
considered as forms of Telepathy; but for the purpose of classification
and distinction we have in this book classed as Telepathic Phenomena
merely those forms and phases of Thought Transference in which there is
an agreement between the telepathic sender and the telepathic receiver,
and in which the experiments are conducted more or less along the lines
of scientific investigation.

Scientific Investigators.

Scientific observers, for a number of years past, have been conducting
careful series of experiments in Telepathy, and many volumes of the
reports of such investigations have been published by various psychic
research societies. Among the eminent scientists who have devoted much
attention to this subject are the following: Professor Henry Sidgewick,
of Cambridge University; Professor Balfour Stewart, of the Royal Society
of England; Rt. Hon. A. J. Balfour, the eminent English statesman and
scientist; Professor William James, the eminent American psychologist;
