“And how does it make that note?” he went on. “Why, in the manner in which phonograph records are made. There are millions of minute dots, depressions, pockmarks on your brain which certainly record what you remember, what you have enjoyed or disliked, or done or said. The surface of the brain anyhow is large enough to furnish writing-paper for the record of all these things, of all your memories. If the impression of an experience has not been acute, the dot is not sharply impressed, and the record fades: in other words, you come to forget it. But if it has been vividly impressed, the record is never obliterated. Mrs. Gabriel, for instance, won’t lose the impression of how she lathered her husband’s face after she had cut his throat. That’s to say, if she did it.” “Now do you see what I’m driving at? Of course you do. There is stored within a man’s head the complete record of all the memorable things he has done and said: there are all his thoughts there, and all his speeches, and, most well-marked of all, his habitual thoughts and the things he has often said; for habit, there is reason to believe, wears a sort of rut in the brain, so that the life-principle, whatever it is, as it gropes and steals about the brain, is continually stumbling into it. There’s your record, your gramophone plate all ready. What we want, and what I’m trying to arrive at, is a needle which, as it traces its minute way over these dots, will come across words or sentences which the dead have uttered, and will reproduce them. My word, what Judgment Books! What a resurrection!” Here in this withdrawn situation no remotest echo of the excitement which was seething through the streets penetrated; through the open window there came in only the tide of the midnight silence. But from somewhere closer at hand, through the wall surely of the laboratory, there came a low, somewhat persistent murmur. “Perhaps our needle--unhappily not yet invented--as it passed over the record of speech in the brain, might induce even facial expression,” he said. “Enjoyment or horror might even pass over dead features. There might be gestures and movements even, as the words were reproduced in our gramophone of the dead. Some people when they want to think intensely walk about: some, there’s an instance of it audible now, talk to themselves aloud.” He held up his finger for silence. “Yes, that’s Mrs. Gabriel,” he said. “She talks to herself by the hour together. She’s always done that, she tells me. I shouldn’t wonder if she has plenty to talk about.”
