Placing himself before the sashless window of the cabin, which opening appeared as a black space pictured against the night, the sage took the candle in his right hand, holding it so that the flame was just below the tip of the nose, and about six inches from his face. Then facing the open window he turned the pupils of his eyes upward, seeming to fix his gaze on the upper part of the open window space, and then he slowly moved the candle transversely, backward and forward, across, in front of his face, keeping it in such position that the flickering flame made a parallel line with his eyes, and as just remarked, about six inches from his face, and just below the tip of his nose. Speaking deliberately, he said: "Now, were I you, this movement would produce a counter irritation of the retina; a rhythm of the optic nerve would follow, a reflex action of the brain accompanying, and now a figure of part of the brain that rests against the skull in the back of my head would be pictured on the retina. I would see it plainly, apparently pictured or thrown across the open space before me." "Incredible!" I replied. "Try for yourself," quietly said my guide. Placing myself in the position designated, I repeated the maneuver, when slowly a shadowy something seemed to be evolved out of the blank space before me. It seemed to be as a gray veil, or like a corrugated sheet as thin as gauze, which as I gazed upon it and discovered its outline, became more apparent and real. Soon the convolutions assumed a more decided form, the gray matter was visible, filled with venations, first gray and then red, and as I became familiar with the sight, suddenly the convolutions of a brain in all its exactness, with a network of red blood venations, burst into existence.[7] [7] This experiment is not claimed as original. See Purkinje's Beitraege zur Kenntniss des Sehens in subjectiver Hinsicht (Prague, 1823 and 1825), whose conclusions to the effect that the shadow of the retina is seen, I-Am-The-Man ignores.--J. U. L. [Illustration: "A BRAIN, A LIVING BRAIN, MY OWN BRAIN."] I beheld a brain, a brain, a living brain, my own brain, and as an uncanny sensation possessed me I shudderingly stopped the motion of the candle, and in an instant the shadowy figure disappeared. "Have I won the wager?" "Yes," I answered. "Then," said my companion, "make no further investigations in this direction." "But I wish to verify the experiment," I replied. "Although it is not a pleasant test, I can not withstand the temptation to repeat it." And again I moved the candle backward and forward, when the figure of my brain sprung at once into existence. "It is more vivid," I said; "I see it plainer, and more quickly than before."
