I touched none of these misplaced things with the exception of the frying-pan, which I needed to cook the sausages I had brought with me; but after I had had my meal, I went through all the rooms and entered the position of every article in a large note-book, making plans of each room, besides a full list of the furniture and ornaments it contained. Later, I went up into the roof and disconnected the water supply, afterwards emptying the cistern and all the pipes. And before I went to bed I turned off the electric light at the main switch. All these precautions, as I need hardly tell you, were absolutely essential. It might appear difficult to explain the moving of a large chest of drawers by the sound of water-pipes or the fusing of an electric wire; but the critics of psychical research have essayed far more difficult tasks than that, to their own entire satisfaction. I went up to the bedroom the Slippertons used to occupy, a little before eleven o'clock. I had with me a couple of spare candles, a new notebook, and a fountain pen. I was even at that time, I may add, a highly trained researcher in every way, and was quite capable of taking a full shorthand report of a seance. I tried my pulse and temperature before getting into bed and found them both normal. So far, there had been no sign of any phenomena; and I was not at all nervous. Indeed, I may say that I have never been nervous with spirits. I had brought the _Pickwick Papers_ upstairs to read in bed--it is always as well to choose some book that has no kind of bearing on the subject of one's investigation--and I was in the middle of the Trial Scene when my attention was caught by the sound of something moving in the room. I had left both windows wide open and the curtains undrawn, and I thought at first that an unusually large moth had flown in and was fluttering against the ceiling. I laid down my book, sat up and looked round the room, but I could see nothing. The night was very still, and the candle on the table by my bed burnt without a flicker. Nevertheless, the sound continued; a soft, irregular fluttering that suggested the intermittent struggle of some feeble winged creature. It occurred to me that a wounded bat or bird might have flown into the room and might be struggling on the floor out of sight near the foot of the bed. And I was about to get up and investigate when the flame of the candle sank a little, and I became aware that the temperature of the room was perceptibly colder. I picked up my note-book at once and made an entry of the circumstances, and the exact time.
