82. The phenomena of which we are now about to treat are, for the most part,
elicited; but it sometimes happens that they occur spontaneously, without any
participation of the medium's will, and even in opposition to it, becoming, in some
cases, very troublesome. And, as though to prove still more conclusively that they are
not the figment of imaginations over-excited by spiritist ideas, they often occur with
persons who have never heard of spiritism, and just when they are least expected.
Phenomena of this spontaneous character, which we may call the practical spiritism of
nature, are very important, because they exclude all suspicion of connivance; for which
reason, we would invite those who are interested in spiritism to collect all the facts of
this description which come to their knowledge, and, above all, to ascertain their reality
by a minute study of the Circumstances under which they may have occurred, in order
to assure themselves that they are not the victims of trickery or illusion.
