"Gentlemen," said Hammer, when silence had fallen. "Although the statements of Professor Sarakoff and Dr. Harden appear fantastical, I believe that they may be nearer the truth than we suppose." His manner, slow, impressive and calm, aroused general attention. Frowning slightly, he drew himself up and clasped the lapels of his coat. "This afternoon," he continued, "I was at the bedside of a sick child who was at the point of death. This child had been visited yesterday by a relative who, two hours after the visit, developed the Blue Disease. Now----" He paused and looked slowly about him. "Now the child was suffering from peritonitis, and there was no possible chance of recovery. Yet that child _did_ recover and is now well." The whole audience was staring at him. Hammer took a deep breath and grasped his coat more firmly. "That child, I repeat, is now well. The recovery set in under my own eyes. I saw for myself the return of life to a body that was moribund. The return was swift. In one hour the transformation was complete, and it was _in that hour_ that the child developed the outward signs of the Blue Disease." 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. "The point of view hinted at by the last speaker is correct," he said. "I can corroborate it to a small extent. This morning I was confined to my bed with the beginnings of a bad influenzal cold. 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." Scarcely had he taken his seat again when a grave scholarly man arose in the gallery. "Gentlemen," he said, "I come from Birmingham; and it is a city of miracles. The sick are being cured in thousands daily. The hospitals are emptying daily. I verily believe that the Blue Disease may prove to be all that Dr. Sarakoff and Dr. Harden claim it to be." The effect of these speakers upon the meeting was remarkable. A thrill passed over the crowded Hall. Hammer rose again. "Let us accept for a moment that this new infection confers immortality on humanity," he said, weighing each word carefully. "What are we, as medical men, going to do? 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.
