Dr. Slade performed several little tricks which he imputed to Spiritual
agency, but which were almost puerile in the simplicity of their
legerdemain, and which have been repeated with perfect success by one of
our number; such as tossing a slate pencil on and sometimes over the
table from a slate held apparently under the table, or the playing of an
accordion when held with one hand under the table. This Medium's fingers
are unusually long and strong, and the accordion, being quite small and
with only four bellows folds, can be readily manipulated with but one
hand, and when under the table is held by the keys.

Two compasses, which we placed on the table during one séance, remained
unaffected by Dr. Slade's presence.

At our last séance with him we noticed two slates which were not with
the other slates on the small table behind him, but were on the floor
resting against the leg of that table, and within easy reach of his hand
as he sat at the larger table. As we had previously seen prepared slates
similarly placed we kept a sharp watch on these slates. Unfortunately,
it was too sharp. Dr. Slade caught the look that was directed at them.
That detected glance was sufficient to prevent the Spirits from sending
us the messages which they had so carefully prepared. The slates were
not produced during the séance, but when it was over one of our number
managed to strike them with his foot so as to displace them and reveal
the writing. None of us present that day will be likely to forget the
hurried way in which these slates were seized by the Medium and washed.

We think it worthy to be recorded that, in reply to a question, Dr.
Slade said that Professor Zoellner watched him closely only during the
first three or four sittings, but that afterwards Professor Zoellner let
