He declares himself specially authorized to mention
by name as present at some of his investigations his colleagues,
Professors Fechner and Scheibner, of the University of Leipsic, and
Professor Weber of Goettingen. These three, he states, were perfectly
convinced of the reality of the observed facts, and that they were not
to be attributed to imposture or prestidigitation. He also mentions the
presence of Professor Wundt at at least one of the sittings.

The phenomena narrated by Zoellner--the bursting of the wooden screen,
the passages of coins out of closed boxes, the abnormal actions of the
solid wooden rings, the tying of knots in the endless cord, the prints
made upon smoked paper by the feet of four-dimentional beings--all these
have become classic in Spiritistic literature, and the accounts may be
obtained in convenient form collected, arranged and translated into
English by Mr. C.C. Massey, of Lincoln's Inn, London.

Of these phenomena themselves, verification is, at this late date,
manifestly out of the question. The only published accounts are those
made by Zoellner, and in the absence of notes made at the time, all
descriptions of phenomena given now by the other persons present would
be valueless, except as indicating the impression made upon them at the
time by the occurrences.

But, though the phenomena themselves cannot be satisfactorily sifted,
the men who were engaged in the investigation are, with the exception of
Zoellner himself, still living, and it occurred to me when in Germany
during the past summer, that a conference with each of these men, and an
inquiry into their qualifications for making such an investigation into
the phenomena of Spiritism, might be of no small value. These men are:
_William Wundt_, Professor of Philosophy in the University of Leipsic;
_Gustav Theodore Fechner_, now Professor Emeritus of Physics in the
University of Leipsic; _W. Scheibner_, Professor of Mathematics in the
University of Leipsic; and _Wilhelm Weber_, Professor Emeritus of
Physics in the University of Goettingen--all of them men of eminence in
their respective lines of scholarship.

On Saturday, June 19th, I called upon Professor Wundt at his home in
Leipsic; with respect to the investigation of 1877-78 he gave me the
following information, which I noted down during my conversation with
him, asking him to repeat the points mentioned as I noted them, so as to
avoid any error or misunderstanding, and which I
