In forcing the jaws of the Dead Man widely apart, in order to accomplish that purpose, the victim contrived to get one of his tormentor's fingers between his teeth, and it was nearly bitten off ere it could be disengaged. This enraged the Doctor so that he was about to kill his enemy instantly, but he checked himself; and having effectually gagged him, he prepared to commence the terrible ordeal.

Taking a lancet from the case, he made an incision in the subject's right arm; then, in the wound, he poured a few drops of the contents of the phial. The effects were instantaneous and terrible; the poison became infused in every vein of the sufferer's body, and his blood seemed changed to liquid fire; he writhed in mighty agony—his heart leaped madly in his breast, in the intensity of his torment—his brain swam in a sea of fire—his eyes started from their sockets, and blood oozed from every pore of his body.

These awful results were produced by a wonderful chemical preparation, known to but few, and first discovered in the days of the Spanish Inquisition. It was then termed the 'Ordeal of Fire;' and the infernal vengeance of hell itself could not have produced torment more intense or protracted; for though it racked every nerve and sinew in the body, filling the veins with a flood like molten lead, it was comparatively slow in producing death, and kept the sufferer for several hours writhing in all the tortures of the damned.

For two mortal hours the miserable wretch endured the torment; while the Doctor stood over him, viewing him with a fixed gaze and an unmoved heart. Then he removed the gag from the sufferer's mouth, and poured a glass of water down his throat, which temporarily assuaged his agony.

'Doctor,' gasped the dying wretch—'for God's sake stab me to the heart, and end my misery! I am in hell—I am floating in an ocean of fire—my murdered victims are pouring rivers of blazing blood upon me—my soul is in flames—my heart is RED HOT! Ah, kill me—kill me!'

The Doctor, after a moment's deliberation, again took an instrument from his case, and skillfully divided the flesh in the region of the abdomen, making an incision of considerable extent. He then produced a small flask of gunpowder, in the neck of which he inserted a straw filled with the same combustible; and in the end of the straw he fastened a small slip of paper which he had previously prepared with saltpetre. Having made these arrangements, he placed the powder flask completely in the victim's abdomen, leaving the slow match to project slightly from the wound. The Dead Man was perfectly conscious during this horrible process, notwithstanding he suffered the most excruciating pain.

'You are going to blow me to atoms, Doctor,' he with difficulty articulated, as a ghastly smile spread over his hideous features—'I thank you for it; although I hate and curse you in this my dying hour. Grant me a moment longer; if the spirits of the dead are allowed to re-visit the earth, my spirit shall visit you! Ha, ha, ha! In a few seconds, I shall be free from the power of your torture—free to follow you like a shadow through life, free to preside in ghastly horror over your midnight slumbers and to breathe constantly in your ear, curses—curses—curses!'

'Miserable devil, your blood-polluted spirit will be too strongly bound to hell, to wander on earth,' said the Doctor, with a contempt not unmingled with pity. 'Farewell, thou man of many crimes; for the wrongs you have done me, I forgive you, but human and divine justice have demanded this sacrifice.'

He ignited a match, touched it to the paper at the end of the straw, and hastily retreated to the further extremities of the room.

It was an awful moment; slowly the paper burnt towards the straw—so slowly, that the victim of this awful sacrifice had time to vent his dying rage in malignant curses, on himself, his tormentor, and his Maker! The straw is reached—the fire runs down to the powder flask with a low hiss—and then—
