my laboratory, and there, with shutters bolted and barred down, with curtains drawn thick and close, so that the very stars might be shut out from the sight of that room, while the crucible hissed and boiled over the lamp, I did what had to be done, and led out what was no longer a woman. But on the table the opal flamed and sparkled with such light as no eyes of man have ever gazed on, and the rays of the flame that was within it flashed and glittered, and shone even to my heart.

Dyson let the little pocket-book fall, and turned and looked again at the opal with its flaming inmost light, and then with unutterable irresistible horror surging up in his heart, grasped the jewel, and flung it on the ground, and trampled it beneath his heel. His face was white with terror as he turned away, and for a moment stood sick and trembling, and then with a start he leapt across the room and steadied himself against the door. There was an angry hiss, as of steam escaping under great pressure, and as he gazed, motionless, a volume of heavy yellow smoke was slowly issuing from the very centre of the jewel, and wreathing itself in snake-like coils above it. And then a thin white flame burst forth from the smoke, and shot up into the air and vanished; and on the ground there lay a thing like a cinder, black and crumbling to the touch.
