He paused. A murmur ran round the hall and then once more came silence.

"I am of the opinion," said Hammer deliberately, "that the cause of the miracle—for it was a miracle—was the Blue Disease. Think, Gentlemen, of a child in the last stages of septic peritonitis, practically dead. Think again of the same child, one hour later, alive, free from pain, smiling, interested—and stained with the Blue Disease. What conclusion, as honest men, are we to draw from that?"

He sat down. At once a man near him got to his feet.

At midday I developed the Blue Disease, and now I am as well as I have ever been in the whole of my life. I attribute my cure to the Blue Disease."

Look into the future—a future free from disease, from death, possibly from pain. Are we to accept such a future passively, or are we, as doctors, to strive to eradicate this new germ as we strive to eradicate other germs?"

Sir Jeremy Jones, with an expression of dismay, raised his hand.

"Surely, surely," he exclaimed shrilly, "we are going too far. That the Blue Disease may modify the course of illness is conceivable, and seems to be supported by evidence. But to assume that it confers immortality——"
