I was impressed with the idea that if I ever made an original discovery in regard to Mars, it would be on that evening, and I believed that I should do it. I trembled with mingled exultation and anxiety, and was obliged to pause to recover my self-control. Finally, I placed my eye to the eye-piece, and directed my gaze upon the portion of the planet in which I was especially interested. My attention soon became fixed and absorbed much beyond my wont, when observing, and that itself implied no ordinary degree of abstraction. To all mental intents and purposes I was on Mars. Every faculty, every susceptibility of sense and intellect, seemed gradually to pass into the eye, and become concentrated in the act of gazing. Every atom of nerve and will power combined in the strain to see a little, and yet a little, and yet a little, clearer, farther, deeper. The next thing I knew I was on the bed that stood in a corner of the observing-room, half raised on an elbow, and gazing intently at the door. It was broad daylight. Half a dozen men, including several of the professors and a doctor from the village, were around me. Some were trying to make me lie down, others were asking me what I wanted, while the doctor was urging me to drink some whiskey. Mechanically repelling their offices, I pointed to the door and ejaculated, “President Byxbee --coming,” giving expression to the one idea which my dazed mind at that moment contained. And sure enough, even as I spoke the door opened, and the venerable head of the college, somewhat blown with climbing the steep stairway, stood on the threshold. With a sensation of prodigious relief, I fell back on my pillow. It appeared that I had swooned while in the observing-chair, the night before, and had been found by the janitor in the morning, my head fallen forward on the telescope, as if still observing, but my body cold, rigid, pulseless, and apparently dead. In a couple of days I was all right again, and should soon have forgotten the episode but for a very interesting conjecture which had suggested itself in connection with it. This was nothing less than that, while I lay in that swoon, I was in a conscious state outside and independent of the body, and in that state received impressions and exercised perceptive powers. For this extraordinary theory I had no other evidence than the fact of my knowledge in the moment of awaking that President Byxbee was coming up the stairs. But slight as this clue was, it seemed to me unmistakable in its significance. That knowledge was certainly in my mind on the instant of arousing from the swoon. It certainly could not have been there before I fell into the swoon. I must therefore have gained it in the mean time; that is to say, I must have been in a conscious, percipient state while my body was insensible.
