“If now, in addition to all these things, you have properly reflected upon the odd disorder of the chamber, we have gone so far as to combine the ideas of a strength superhuman, an agility astounding, a ferocity brutal, a butchery without motive, a _grotesquerie_ in horror absolutely alien from humanity, and a voice foreign in tone to the ears of men of many nations, and devoid of all distinct or intelligible syllabification. What result, then, has ensued? What impression have I made upon your fancy?” I shuddered as Dupin asked me the question. “A madman,” I said, “has done this deed—some raving maniac, escaped from a neighboring _Maison de Santé_.” “In some respects,” he replied, “your idea is not irrelevant. But the voices of madmen, even in their wildest paroxysms, are never found to tally with that peculiar voice heard upon the stairs. Madmen are of some nation, and their language, however incoherent in its words, has always the coherence of syllabification. Besides, the hair of a madman is not such hair as I now hold in my hand. I disentangled this little tuft from among the tresses remaining upon the head of Madame L’Espanaye. Tell me what you can make of it.” “Good God,” I said, completely unnerved, “this hair is most unusual—this is no _human_ hair.” “I have not asserted that it was,” said he, “but before we decide upon this point, I wish you to glance at the little sketch which I have here traced upon this paper. It is a fac-simile drawing of what has been described in one portion of the testimony as ‘dark bruises, and deep indentations of finger nails,’ upon the throat of Mademoiselle L’Espanaye, and in another, (by Messrs. Dumas and Etienne,) as ‘a series of livid spots, evidently the impression of fingers.’ “You will perceive,” continued my friend, spreading out the paper upon the table before us, “you will perceive that this drawing gives the idea of a firm and fixed hold. There is no _slipping_ apparent. Each finger has retained—possibly until the death of the victim—the fearful grasp by which it originally imbedded itself. Attempt now to place all your fingers, at one and the same time, in the impressions as you see them.” I made the attempt in vain. “We are possibly not giving this matter a fair trial,” he said. “The paper is spread out upon a plane surface; but the human throat is cylindrical. Here is a billet of wood, the circumference of which is about that of the throat. Wrap the drawing around it, and try the experiment again.” I did so; but the difficulty was even more obvious than before. “This,” I said, “is the mark of no human hand.” “Assuredly it is not,” replied Dupin; “read now this passage from Cuvier.”
