The passage pointed out to me was expressed in these terms:
"Dr. Abel informed me," says Mr. Combe, "of an Irish porter to a
warehouse, who forgot, when sober, what he had done when drunk; but,
being drunk, again recollected the transactions of his former state of
intoxication. On one occasion, being drunk, he had lost a parcel of some
value, and in his sober moments could give no account of it. Next time
he was intoxicated, he recollected that he had left the parcel at a

"Plain again?" asked Ezra Jennings.
"As plain as need be."
He put back the slip of paper in its place, and closed the book.
"Are you satisfied that I have not spoken without good authority to support me?" he asked. "If not, I have only to go to those book-shelves, and you have only to read the passages which I can point out to you."
"I am quite satisfied," I said, "without reading a word more."
"In that case, we may return to your own personal interest in this matter. I am bound to tell you that there is something to be said against the experiment as well as for it.

I believe, Mr. Blake, I have now stated the question, on both sides of it, as fairly as I can, within the limits that I have imposed on myself. If there is anything that I have not made clear to you, tell me what it is—and if I can enlighten you, I will."
"All that you have explained to me," I said, "I understand perfectly. But I own I am puzzled on one point, which you have not made clear to me yet."
"What is the point?"
"I don't understand the effect of the laudanum on me. I don't understand my walking down stairs, and along corridors, and my opening and shutting the drawers of a cabinet, and my going back again to my own room. All these are
