It was too late, the one vial was empty, and the professor's body lay lifeless. In mental agony the stranger grasped the second vial and emptied its contents also into the professor's head, and stopped the hole with the cork. Miraculously Professor Carbonic opened his eyes, and rose to his feet. His eyes were like balls of fire; his lips moved inaudibly, and as they moved little blue sparks were seen to pass from one to another. His hair stood out from his head. The chemical reaction was going on in the professor's brain, with a dose powerful enough to restore ten men. He tottered slightly. Murray Attic, now thoroughly alive, sat up straight in bed. He grasped the brass bed post with one hand and stretched out the other to aid the staggering man. He caught his hand; both bodies stiffened; a slight crackling sound was audible; a blue flash shot from where Attic's had made contact with the bed post; then a dull thud as both bodies struck the floor. Both men were electrocuted, and the formula is still a secret.
