in and will walk down among the
sitters, shaking hands with them, touching them on the cheek, or even
embracing some loved one. In rare cases these materialized forms are
able to converse with the sitters in the circle, just as plainly as when
in earth life.

Scientific Proof of Materialization.

It is not the purpose of this book to prove the existence of mediumistic
phenomena--rather it points out the means and methods whereby the
student may obtain such proof for himself or herself. But it may be
suggested here that the sceptic may find an abundance of proof of the
genuineness of materialization phenomena in the records and reports made
by eminent scientists, statesmen, and others. Particularly, the report
of Sir William Crookes, the eminent English scientist, will furnish such
proof to the inquirer who demands "scientific proof" before he will
believe anything out of the usual. Sir William Crookes has given
convincing evidence of the genuineness of spirit materialization, even
going so far to offer records of the weight of materialized spirits, and
their photographs taken by him--in some instances the photographs
showing the forms of both medium and spirit materialization.

How to Conduct a Materializing Seance.

In sitting for materialization, the circle should maintain the same
general demeanor that it observes at other times. Silence or dignified
conversation may be indulged in, but joking or levity should be
forbidden. Hands should be held, and reverent singing indulged in. It
should be remembered that this phase of mediumistic phenomena is not
something apart and distinct from the lesser phases which have been
described in detail in this book. On the contrary, it is simply a matter
of degree, and the same general principles underlie all phases of
mediumistic phenomena. Therefore, it is not necessary to repeat the
instructions regarding the conduct of the circle, or the rules for the
development of the medium. Read the earlier chapters for the same, which
are equally applicable in this place as in the places in which they
originally appeared.

Trumpet Mediumship.

In what is known as "trumpet mediumship," the sound of the voice of the
communicating spirit is increased in power by the use of a trumpet
shaped arrangement of paper, card-board, tin, or aluminum. There is no
particular virtue in the material used, and anyone may make a
serviceable trumpet out of heavy paper or thin card-board. The princi
