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 certain house, and there being no address on it, it had remained there safely, and was got on his calling for it."
"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 bookshelves, 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. If we could, this year, exactly reproduce, in your case, the conditions as they existed last year, it is physiologically certain that we should arrive at exactly the same result. But this--there is no denying it--is simply impossible. We can only hope to approximate to the conditions; and if we don't succeed in getting you nearly enough back to what you were, this venture of ours will fail. If we do succeed--and I am myself hopeful of success--you may at least so far repeat your proceedings on the birthday night, as to satisfy any reasonable person that you are guiltless, morally speaking, of the theft of the Diamond. 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
