Richardson's head nodded again, and for a moment Franstein, still holding the hand continued to look up into Richardson's face above him. Then he released the hand and said: "Now you can lie down on the couch if you like."
Richardson went to the couch and stretched himself out on it.
"I've heard a lot about this," Sandra said, "but I've never seen it done."
Franstein smiled at her. "You've just seen it done, my dear," he said, and as she stared back at him in astonishment, added: "He's a very good subject. Now, when that machine is ready...."
"If I'm right in what I think," Franstein said a few minutes later to Snow, who stood by the table on which now rested the recorder, and to Sandra who was at the head of the couch looking down on her husband who lay there, his eyes half-closed, "you're going to hear something very surprising. Please don't make a sound."
They nodded their heads, and Franstein seated himself on the edge of the couch, leaned over Richardson, and spoke softly: "You hear me, Ham?"
"Yes, I hear you."
"Then listen." Franstein turned and nodded to Snow. The machine was switched on and there came, clearly, the chanted sounds of the test. They finished and the machine was switched off. "You heard, Ham?"
"Yes, I heard."
"You made those sounds that we just heard."
