“Is it anything like what they call trepanning, or trephining?”

“But very remotely. A partial fracture, and a depression, of the bone are caused; but no particle of it is removed.”

“What is the worst that could happen, in case of the operation miscarrying? What would be the chances of the subject's losing not only his memory, but his reason—becoming an imbecile or a maniac?”

“There is no chance of that. The worst that could happen would be death. It is as safe an operation as any in which the knife is employed. But, of course, in all operations which involve the use of the knife there is some danger. There is always the possibility of inflammation. But that possibility is by no means a probability. The chances are largely against it.”

“So that you are sure one of two things would happen either the operation would prove a success, or the patient would die?”

“Exactly so.”

“How much time would have to elapse after the operation, before the patient would be able to take care of himself again—before he would have regained sufficient knowledge to act as a responsible and competent human being?”

“I should say a year. Perhaps more, perhaps less. But I will say a year.”

“And during that year? Suppose, for example, that I should offer myself to you as a subject—how should I be provided for during the period of my incompetence? And what education should I receive?”

“You would be provided for by me. You would be lodged and taken care of here in this house. My sister, ten years younger than I, the kindest and the gentlest of women, would be your nurse, your companion, and your teacher. We would give you the same education that we would give a child of our own.”
