"But the after-effects!" persisted Henry. "Patients must surely feel that they have forgotten something, even if they do not know what it is. They must feel that there is something gone out of their minds. I should think this sensation would leave them in a painfully bewildered state."

"There seems to be a feeling of slight confusion," said the doctor; "but it is not painful, not more pronounced, indeed, than that of persons who are trying to bring back a dream which they remember having had without being able to recall the first thing about what it was. Of course, the patient subsequently finds shreds and fragments of ideas, as well as facts in his external relations, which, having been connected with the extirpated subject, are now unaccountable. About these the feeling is, I suppose, like that of a man who, when he gets over a fit of drunkenness or somnambulism, finds himself unable to account for things which he has unconsciously said or done. The immediate effect of the operation, as I intimated before, is to leave the patient very drowsy, and the first desire is to sleep."

"Doctor," said Henry, "when you talk it all seems for the moment quite reasonable, but you will pardon me for saying that, as soon as you stop, the whole thing appears to be such an incredible piece of nonsense that I have to pinch myself to be sure I am not dreaming."

The doctor smiled.

"Well," said he, "I have been so long engaged in the practical application of the process that I confess I can't realize any element of the strange or mysterious about it. To the eye of the philosopher nothing is wonderful, or else you may say all things are equally so. The commonest and so-called simplest fact in the entire order of nature is precisely as marvellous and incomprehensible at bottom as the most uncommon and startling. You will pardon me if I say that it is only to the unscientific that it seems otherwise. But really, my dear sir, my process for the extirpation of thoughts was but the most obvious consequence of the discovery that different classes of sensations and ideas are localized in the brain, and are permanently identified with particular groups of corpuscles of the grey matter. As soon as that was known, the extirpating of special clusters of thoughts became merely a question of mechanical difficulties to be overcome, merely a nice problem in surgery, and not more complex than many which my brethren have solved in lithotomy and lithotrity, for instance."

"I suppose what makes the idea a little more startling," said Henry, "is the odd intermingling of moral and physical conceptions in the idea of curing pangs of conscience by a surgical operation."

"I should think that intermingling ought not to be very bewildering," replied the doctor, "since it is the usual rule. Why is it more curious to cure remorse by a physical act than to cause remorse by a physical act? And I believe such is the origin of most remorse."

"Yes," said Henry, still struggling to preserve his mental equilibrium against this general overturning of his prejudices. "Yes, but the mind consents to the act which causes the remorse, and I suppose that is what gives it a moral quality."

"Assuredly," replied the doctor; "and I take it for granted that patients don't generally come to me unless they have experienced very genuine and profound regret and sorrow for the act they wish to forget. They have already repented it, and, according to every theory of moral accountability, I believe it is held that repentance balances the moral accounts. My process, you see then, only completes physically what is already done morally. The ministers and moralists preach forgiveness and absolution on repentance, but the perennial fountain of the penitent's tears testifies how empty and vain such assurances are. I fulfil what they promise. They tell the penitent he is forgiven. I free him from his sin. Remorse and shame and wan regret have wielded their cruel sceptres over human lives from the beginning until now. Seated within the mysterious labyrinths of the brain, they have deemed their sway secure, but the lightning of science has reached them on their thrones and set their bondmen free;" and with an impressive gesture the doctor touched the battery at his side.

Without giving further details of his conversation with this strange Master of Life, it is sufficient to say that Henry finally agreed upon an appointment for Madeline on the following day, feeling something as if he were making an unholy compact with the devil. He could not possibly have said whether he really expected anything from it or not. His mind had been in a state of bewilderment and constant fluctuation during the entire interview, at one moment carried away by the contagious confidence of the doctor's tone, and impressed by his calm, clear, scientific explanations and the exhibition of the electrical apparatus, and the next moment reacting into utter scepticism and contemptuous impatience with himself for even listening to such a preposterous piece of imposition. By the time he had walked half a block, the sights and sounds of the busy street, with their practical and prosaic suggestions, had quite dissipated the lingering influence of the necromantic atmosphere of Dr. Heidenhoff's office, and he was sure that he had been a fool.
