"Mother," he said gently. "Don't be alarmed. It is successful. I am here, in Professor Burr's body."
"Yes," she cried, hysterically. It was too weird to believe. It seemed dim to her, unearthly.
"Are you all right, darling?" she asked timidly.
"Yes. I felt nothing beyond a momentary giddy spell, a bit of nausea and mental stiffness. It was strange, and I have a slight headache. However, all is well."
He grinned at her, laughed with the voice which was not his, yet which she recognized as directed by her son's spirit. The laugh was cracked and unlike Allen's whole-hearted mirth, yet she smiled in sympathy.
"Yes, the first part is a success," said the man. "Our egos have interchanged. Soon, our bodies will undergo the transformation, and then I must keep under cover. I dislike Burr—yet he is a great man. He has saved me. I suppose the slight headache which I feel is one bequeathed me by Burr. I hope he inherits my shivers and terrors and the neuralgia for the time being, so he will get some idea of what I have undergone."
He had got down from the oscillating platform, the spirit of her son in Ramsey's body.
"What—what are you doing now?" she asked.
"I must carry out the rest of it myself," he said. "Burr directed me when we talked yesterday. It is more difficult when one subject is out of the laboratory, and the tubes must be checked."
