I style it "The Case of Martin Tristram." It is reproduced from a magazine published some three years ago.

After Martin Tristram once took up spiritualism his visits to me became most erratic, and I not only never knew when to expect him, but I was not always sure, when he did come, that it was he.

This sounds extraordinary—to see a man is assuredly to recognize him! Not always—by no means always!

There are circumstances in which a man loses his identity, when his "ego" is supplanted by another ego, when he ceases to be himself, and assumes an individuality which is entirely different from himself.

This is undoubtedly the case in madness, imbecility, epilepsy, so-called total loss of memory through cerebral injury, hypnotism, sometimes in projection when the astral body gets detained, and also not infrequently in investigating peculiar instances of psychic phenomena.

But if the astral body has been evicted from its carnal home, whither has it gone? and what is the nature of the thing that has taken its place?

Ah! These are indeed puzzles—puzzles I am devoting a lifetime to solve.

There have been moments when unseen hands have gradually begun to pull aside the obscuring veil, when the identity of the usurping spirit has seemed on the verge of being disclosed to me, and I have been about to be initiated into the greatest and most zealously guarded of all secrets.

There have been times, I say, when my occult researches have actually brought me to this climax; but up to the present I have invariably been disappointed—the curtain has suddenly fallen, the esoteric ego has shrunk into its shell, and the mystery surrounding it has remained impenetrable.

This is but one, albeit perhaps the most striking, of the many methods through which the superphysical endeavours to get in immediate contact with the physical.
