What can I, what can my readers decide, on a rational consideration of the whole matter?
It is, no doubt, very baffling to judge how rightly to think about it.

I have stated a few facts that have come under my own personal knowledge; but there are thousands of others similar and even more extraordinary, which numerous persons quite as credible as I am can vouch for in like manner to be true facts while remaining unexplained miracles.

For myself, I must suspend judgment; waiting to see what in these wonderful times--some further development of electricity, for example, may haply produce for us.

After recent marvels of the telephone, microphone, photophone, and I know not what others, why should not some Edison or Lane Fox stumble upon a form of psychic force emanating from our personal nervous organisation, and capable of operating physically on all things round us, the immaterial conquering the material it pervades?
Some such vague theory as to spiritualistic manifestations may be a far more rational as well as pleasing explanation of these modern marvels than to suppose that our dead friends come at any medium's summons to move tables, talk bad grammar, and play accordions; or that angels, good and evil, are allowed to be employed in mystifying or terrifying the frivolous assisters at a _seance_.
Beyond and after this, I might add, but for its too great length, the indisputable testimony of certain friends of mine as to inexplicable writings on locked slates and paper, the revelation of secrets, nay visible apparitions, and both records of the secret past and revelations of the still more secret future afterwards fulfilled,--to all which I cannot, as an honest man and a believer in human evidence, refuse to give a distinct testimony, even though conjurors perpetually baffle our confused judgment.
In this connection I will extract from one of my Archive-books the curious story of a mysterious key in which my family are still interested: for the secret is not yet solved.

In the fourteenth volume, then, of my Archives occurs this long note, accompanied by the drawing which I made years ago of the weird-looking key: with a loose ring handle, a threefold staircase body, and a strangely ringed column.
"My father died in his sleep, December 8, 1844, at Southwick House, in Windsor Park, on the same night after its owner, Lord Limerick, had also died there in his arms, my father having been his medical friend for thirty years.
