"It is a question of cubic capacity," said he; "a man with so large a brain must have something in it." - Arthur Conan Doyle

Our chambers were always full of chemicals and of criminal relics which had a way of wandering into unlikely positions, and of turning up in the butter-dish or in even less desirable places. But his papers were my great crux. He had a horror of destroying documents, especially those which were connected with his past cases, and yet it was only once in every year or two that he would muster energy to docket and arrange them; for, as I have mentioned somewhere in these incoherent memoirs, the outbursts of passionate energy when he performed the remarkable feats with which his name is associated were followed by reactions of lethargy during which he would lie about with his violin and his books, hardly moving save from the sofa to the table. Thus month after month his papers accumulated, until every corner of the room was stacked with bundles of manuscript which were on no account to be burned, and which could not be put away save by their owner. One winter's night, as we sat together by the fire, I ventured to suggest to him that, as he had finished pasting extracts into his common-place book, he might employ the next two hours in making our room a little more habitable. He could not deny the justice of my request, so with a rather rueful face he went off to his bedroom, from which he returned presently pulling a large tin box behind him. This he placed in the middle of the floor and, squatting down upon a stool in front of it, he threw back the lid. I could see that it was already a third full of bundles of paper tied up with red tape into separate packages.

When a doctor does go wrong he is the first of criminals.

So it was, my dear Watson, that at two o'clock today I found myself in my old armchair in my own old room, and only wishing that I could have seen my old friend Watson in the other chair which he has so often adorned.
