A slight shudder came over me as I was entering the inner court of the College of Gottingen. It was, however, but momentary; and on recovering from it, I felt both taller and heavier, and altogether more vigorous, than the instant before. Being rather nervous, I did not much mind these feelings, imputing them to some sudden determination to the brain, or some unusual beating about the heart, which had assailed me suddenly, and as suddenly left me. On proceeding, I met a student coming in the opposite direction. I had never seen him before, but as he passed me by, he nodded familiarly--"There is a fine day, Wolstang."--"What does this fellow mean?" said I to myself. "He speaks to me with as much ease as if I had been his intimate acquaintance. And he calls me Wolstang--a person to whom I bear no more resemblance than to the man in the moon." I looked after him for some time, pondering whether I should call him back and demand an explanation; but before I could form any resolution, he was out of my sight. Thinking it needless to take any further notice of the circumstance, I went on. Another student, whom I did not know, now passed me.--"Charming weather, Wolstang."--"Wolstang again!" said I; "this is insufferable. Hello, I say! what do you mean?" But at this very moment he entered the library, and either did not hear my voice, or paid no attention to it. As I was standing in a mood between rage and vexation, a batch of Collegians came up, talking loud and laughing. Three, with whom I was intimately acquainted, took no notice of me; while two, to whom I was totally unknown, saluted me with "Good morning, Wolstang." One of these latter, after having passed me a few yards, turned round and cried out, "Wolstang, your cap is awry." I did not know what to make of this preposterous conduct. Could it be premeditated? It was hardly possible, or I must have discovered the trick in the countenances of those who addressed me. Could it be that they really mistook me for Wolstang? This was still more incredible, for Wolstang was fully six inches taller, four stones heavier, and ten years older than I. I found myself in a maze of bewilderment in endeavouring to discover the cause of all this. I reflected upon it in vain, summoning to my assistance the aids of Logic and Metaphysics to unravel the mystery. Nay, Euclid was not forgotten. I called to mind the intricate problems of science which a rigid study of this Prince of Mathematicians had enabled me to solve; but on the present occasion my thoughts, though screwed to the utmost pitch of philosophical acumen, completely failed in their aim.
