ugh the body of the subject? (We know that these high-tension
currents will themselves create an electric aura around the body.) What
becomes of the aura after death; and what changes, if any, does it
undergo at the moment of death? Such are a few of the questions which
the psychic student might ask himself, and which certainly call for
solution.

Once more: is "psychometry" a fact? If objects can retain certain
"influences" within them, what is their nature, and how are they
retained? How does the sensitive perceive these impressions? Is there
not a connection between these phenomena and haunted houses? or between
the "charging-up" of a table or planchette board before it proceeds to
answer questions and behave in the manner it is often reported to do?

What is the nature of the "cold breeze" which is so often experienced,
not only at seances, but during very many psychic phenomena, both of the
experimental and spontaneous types, in all parts of the world? Is it a
physical breeze, or is it purely "psychical"? Could it be collected and
analysed, as was suggested in the case of the cold breeze issuing from
the scar on Eusapia Palladino's forehead? What is its source? And what
is its object? On this subject alone much suggestive and valuable
research might be undertaken.

Take the simple phenomena of _raps_. What produces them? What is the
bond between the hand of the medium which makes a gesture in the
direction of the table, and the table itself? What is the nature of the
physical impact upon the table? Are these raps due to exteriorized vital
force? If so, does this energy exude from the nerve termini, or is it
connected only with the etheric body or double? Can these raps be
controlled at will, or directed and controlled when the subject is under
hypnosis? Can this energy be directed at will? Could it not impress
delicate physical instruments? Might not a connection be thus
established between these phenomena and the impressions of hands and
faces, etc., occasionally seen in the presence of Eusapia and other
mediums?

Then the phenomena of materialization! Here is a wide field for study
indeed! How can such an organism be built up? Out of what materials is
it constructed? What degree of density can be attained? What is the
power which manipulates this matter? and what is the structure of the
matter itself? How can _will_ plastically mould matter in space? On what
framework, so to speak, is the body constructed? Wh
