Then I could guarantee your friend the complete extirpation of any class of inconvenient recollections she might desire removed, whether they were morbid or healthy; for since the great fact of the physical basis of the intellect has been established, I deem it only a question of time when science shall have so accurately located the various departments of thought and mastered the laws of their processes, that, whether by galvanism or some better process, the mental physician will be able to extract a specific recollection from the memory as readily as a dentist pulls a tooth, and as finally, so far as the prevention of any future twinges in that quarter are concerned.

Macbeth's question, 'Canst thou not minister to a mind diseased; pluck from the memory a rooted sorrow; raze out the written troubles of the brain ?' was a puzzler to the sixteenth century doctor, but he of the twentieth, yes, perhaps of the nineteenth, will be able to answer it affirmatively." "Is the process at all painful ?" "In no degree, my dear sir.

Patients have described to me their sensations many times, and their testimony is quite in agreement.

When the circuit is closed there is a bubbling, murmurous sound in the ears, a warm sensation where the wires touch the cranium, and a feeling as of a motion through the brain, entering at one point and going out at another.
There are also sparks of fire seen under the closed eyelids, an unpleasant taste in the mouth, and a sensation of smell; that is all." "But the mental sensations ?" said Henry.

"I should think they must be very peculiar, the sense of forgetting in spite of one's self, for I suppose the patient's mind is fixed on the very thoughts which the intent of the operation is to extirpate." "Peculiar?
Oh no, not at all peculiar," replied the doctor.
