Lord Seymour, "that your ghost appeared
neither sooner nor later than you wished him?"

"The ghost was in the room for some time before I called him, but while
the room was lighted, the shade was too faint to be perceived. When the
formula of the conjuration was finished, I caused the cover of the box,
in which the spirit was burning, to drop down, the saloon was darkened,
and it was not till then that the figure on the wall could be distinctly
seen, although it had been reflected there a considerable time before."

"When the ghost appeared, we all felt an electric shock. How was that
managed?"

"You have discovered the machine under the altar. You have also seen
that I was standing upon a silk carpet. I directed you to form a
half-moon around me, and to take each other's hands. When the crisis
approached, I gave a sign to one of you to seize me by the hair. The

I touched it with my hand."

"You ordered Count O----- and myself," continued Lord Seymour, "to hold
two naked swords crossways over your head, during the whole time of the

"Merely to give a greater solemnity to the scene, and to excite your
imaginations by the strangeness of the proceeding."

"The second apparition prevented your ghost from speaking," said the
prince. "What should we have learnt from him?"

"Nearly the same as what you heard afterwards. It was not without
design that I asked your highness whether you had told me everything
that the deceased communicated to you, and whether you had made any
further inquiries on this subject in his country. I thought this was
necessary, in order to prevent the deposition of the ghost from being
contradicted by facts with which you were previously acquainted.
Knowing likewise that every man in his youth is liable to error,
I inquired whether the life of your friend had been irreproachable,
and on your answer I founded that of the ghost."

"Your explanation of th
