specially with a view of informing myself whether the slate
used in both instances was the same.

(Resuming, from notes): The Medium proposed that the Committee should
retain the slate upon which the long message appeared. The slate was
accordingly retained by the Committee.

Professor Thompson (addressing Mr. Sellers): Was not that slate the one
that I held at the time referred to?

Mr. Sellers: It was. The slate was held by you at the same time that it
was held by the Medium.

Professor Thompson: Then there is an additional fact to be noted in
regard to it. That fact is this. When the sounds indicating the writing
process had ceased, I endeavored to pull the slate away from under the
table, but the Medium resisted my effort, and by powerful exertion
jerked the slate out toward himself. The substitution of one slate for
the other was probably made at this time, and the slate so substituted
was then placed on the table.

Mr. Sellers: That is true, most assuredly I saw the substitution, and
Mr. Furness also saw it very plainly. From his position Mr. Furness saw
the Medium take up the other slate.

NOTE.--An explanation was here made by Mr. Furness to the effect that
his knowledge of the substitution here spoken of was inferential, but
that at another period of the seance he did distinctly see the Medium
grasp an unused slate.

Mr. Sellers here resumed, from his notes:

The Medium then proposed to attempt the experiment of causing the chair
upon which Professor Thompson sat, to rise from the floor, without
external agency other than that of the hand of the Medium on the back of
the chair. In answer to the question, 'Will you try to lift the chair?'
the response was 'Yes.' Mr. Sellers, being requested to write a question
on the back of the slate near him, wrote the following, 'What is the
time?' After some little time, during which the Medium furtively glanced
at the slate, the answer was given, 'A little after twelve.'

Upon being requested to open his left hand and hold it thus extended in
a position beneath the top of the table to his left, Mr. Sellers
complied with the request, when a slate, which had been held by the
Medium under the opposite leaf, was passed across, and, after touching
Mr. Sellers's hand, fell to the floor. After several repetitions, the
slate was passed into Mr. Sellers's hand, but the experiment was
accompanied by a motion of the Medium which was evidently such as would
have been made if
