“Whoever you are, I forgive you for the attempt to prevent myself, a son of Adam, wedding with this woman, Evlambéa, the Bright-shining Daughter of Ish; I forgive you for persecuting her toward a marriage with another, which marriage must have doomed me to a fate I have for centuries shrunk from; I forgive you all the woe you have caused me, because gratitude for what you have done for me exacts this; and because I suspect your agent saved my life when the retort burst in Boston, when I was repeating La Brière’s experiment with phosphorus. Through you, or such as you, I have learned priceless secrets. The mystery of Magic Mirrors I am grateful for being taught. The secret of ages--the art of making the Elixir of Life, whereof whosoever shall drink shall never know decay, but so long as once a year he shall quaff thereof, may enjoy perpetual youth--I am inexpressibly thankful for. I shall never use this secret for that purpose, but five of the seven ingredients, when mingled, constitute what chemistry has sought in vain; and bequeathing this portion of the formulæ to my friend, and through him to the medical world, I shall atone for my few faults by giving life to thousands. “Freely, without force or compulsion, I solemnly promise to sleep the sleep of Sialam before I quit this house, and in it will truly answer you all I may be able to, on condition that you previously clear up the mystery surrounding yourself; thus voluntarily giving you what an age of fraud would not enable you to obtain, you first solemnly promising, by Him by whose will you exist, be you man or demon, not to influence me, either now or when I shall slumber.” A gleam of sudden joy flashed from the eyes of the strange being before us. He looked like a bridegroom in the fullness of his joy, and clasping both hands--pale, thin, bluish-white hands--upon his breast, he looked up and said: “So be it! I solemnly bind myself, by the most terrible oath conceivable, that I accept all your conditions.” Then going to the recess mentioned before, he brought thence a semi-circular screen, a little taller than a man, and about four feet in diameter. This he requested the Commissary of Police to examine, who did so, and declared it to be nothing but a common bedside screen. “You are right! it _is_ nothing but a bedside screen. Such as it is, however, I request you to select for it any spot you choose upon the stone floor of either of these rooms. I shall want to go behind it; and that you may not harbor a thought of an intended evasion on my part, I request that you call your men into the room and give them orders to _shoot me_ if I attempt to pass them!” “Just as you please, monsieur! Pierre, call the guard.”
