the outside, but could still be heard rattling inside, and
the obdurate Spirits were abandoned for the day.--H.H.F.]

The slate was secured as follows:

[Illustration]

The two leaves of the slate were fastened by four screws at 1, 2, 3 and
4; one side of the slate was already secured by the hinges 8, 8; the
slate had then been wrapped by the tape 9, 9, as indicated, the knot
being at 4; seals had then been set over the heads of the screws, upon
the tape, at 1, 2, 3 and 4, and also over the ends of the screws, upon
the tape, on the other side of the slate; a seal was also placed upon
the ends of the tape at 5; and two seals at one corner, at the places
indicated by 6 and 7. The corner marked by the arrow (<--) was protected
only by the screws and seals at 3 and 4.

When the slate was shaken no sound of the rattling of the pencil was
heard--a pencil-scrap having been enclosed as usual in the slate when it
was sealed. The Medium had declared that the pencil was gone, but said
she did not know whether there was writing on the slate or not.

The seals were first examined and declared intact.

Then Dr. Leidy pushed a thin knife-blade between the slates at the
unprotected corner, marked by the arrow on the sketch.

Then Mr. Sellers pushed in a thick knife-blade a little to one side of
Dr. Leidy's. (The exact place is marked on the rim of the slate
itself.) Both the blades were thrust straight in--Dr. Leidy's exactly at
the corner, and Mr. Sellers's at the point marked, and neither of them
was worked about between the slates.

The slates were thus separated by the thick knife-blade about one-tenth
of an inch.

The seals were not broken by this.

While the slates were thus separated, it was noticed that the wood was
discolored and rubbed glossy on the sides of the crack.

Mr. Sellers then removed the tape, seals and screws.

The slate being opened, no pencil was found and no pencil-marks appeared
on the slate.

The rims were worn smooth and blackened at the corner where the slates
could be separated; this was very distinct.

Some soap-stone dust, which Dr. Koenig identified under a microscope as
the same with a remaining fragment of the pencil inserted (which Mr.
Furness had preserved), was found rubbed into the same corner, showing
that _the slates had been separated and the piece of pencil worked out_.

Mr. Furness then produced three slates of the same sort (with hinges,
and about 8 in. by 6.) to be used i
