There are often found persons so closely in psychic harmony with each
other that they very often are able to ask questions and receive answers
from each other, even though great distances separate them. Some
particular times there is a better psychic harmony existing between the
same persons than is found at other times. All this, of course, affects
the success of the experiment. It is surprising what wonderful results
along these lines may be obtained by almost any person of average
intelligence, after a little careful, patient, conscientious practice.

But there have been phenomena obtained as the result of long series of
careful experiments which are, in a way, even more wonderful than these
somewhat less deliberate experiments just mentioned. I allude to the
experiments of a number of earnest, careful scientific students, who
surrounded themselves with every precaution against over-enthusiasm,
fraud, and coincidence. Prominent among this class of investigations we
find those conducted by the Society for Psychical Research, of England,
which really established a firm basis for the work of other investigators
who followed the general methods of the said society. In the following
chapter, I shall give you a somewhat extended statement of the results of
such investigations, because this information is important to every
student of psychic phenomena, not only because it establishes a firm
scientific basis for his studies and beliefs, but also because it gives
him important information which he may apply in the course of his own
experimental work.

I may mention that the investigations into the subject of telepathy, and
kindred subjects, under the auspices of the society just mentioned, were
conducted by men of careful scientific training and experience, and under
the general supervision and approval of the officers of the society, among
which have been numbered such eminent men as Prof. Henry Sidgwick, of
