At the beginning of the tale, the narrator surveys and categorizes the people around him in a similar way as Walt Whitman in "Song of Myself". Poe's narrator, however, lacks Whitman's celebratory spirit. While viewing these people, the narrator is able to ascertain a great deal of information about them based on their appearance and by noting small details. For example, he notices that a man's ear sticks out a small amount, indicating he must be a clerk who stores his pen behind his ear. Poe would later incorporate this ability to observe small details in his character C. Auguste Dupin. All of this is a virtuoso performance of the representation of social typicality; it owes something to Dickens’s Sketches by Boz, but there is also something of the moralizing medieval Vice in its parade of degenerates, of depraved women and of social outcasts. In one sense this is a sideshow, a digression from the main line of the narrative, which is concerned with the crowd only as an abstract force; in another, however, it brings to the fore the sense that it is only through these social clichés that the crowd can be made humanly understandable.
