Then [Kovalev] halted as though riveted to earth. For in front of the doors of a mansion he saw occur a phenomenon of which, simply, no explanation was possible. Before that mansion there stopped a carriage. And then a door of the carriage opened, and there leapt thence, huddling himself up, a uniformed gentleman, and that uniformed gentleman ran headlong up the mansion's entrance-steps, and disappeared within. And oh, Kovalev's horror and astonishment to perceive that the gentleman was none other than—his own nose! (2.11)
"Already it had entered a stagecoach, and was about to leave for Riga with a passport made out in the name of a certain civil servant. And, curiously enough, I myself, at first, took it to be a gentleman. Luckily, though, I had my eyeglasses on me. Soon, therefore, I perceived the 'gentleman' to be no more than a nose. […]"
"Do not trouble, sir. Knowing how greatly you stand in need of it, I have it with me. It is a curious fact, too, that the chief agent in the affair has been a rascal of a barber who lives on the Vozkresensky Prospekt, and now is sitting at the police station. For long past I had suspected him of drunkenness and theft, and only three days ago he took away from a shop a button-card. Well, you will find your nose to be as before."
And the officer delved into a pocket, and drew thence the nose, wrapped in paper. (2.106-110)
Everyone's mind was, at that period, bent upon the marvelous. Recently experiments with the action of magnetism had occupied public attention, and the history of the dancing chairs of Koniushennaia Street also was fresh. So no one could wonder when it began to be said that the nose of Collegiate Assessor Kovalev could be seen promenading the Nevsky Prospekt at three o'clock, or when a crowd of curious sightseers gathered there. Next, someone declared that the nose, rather, could be beheld at Junker's store, and the throng which surged thither became so massed as to necessitate a summons to the police […] Next, word had it that the nose was walking, not on the Nevsky Prospekt, but in the Taurida Park, and, in fact, had been in the habit of doing so for a long while past, so that even in the days when Khozrev Mirza had lived near there he had been greatly astonished at the freak of nature. This led students to repair thither from the College of Medicine, and a certain eminent, respected lady to write and ask the Warden of the Park to show her children the phenomenon, and, if possible, add to the demonstration a lesson of edifying and instructive tenor.
