The room was but small, and clients seemed to have had a habit of bscking up against the wall: the wall especially opposite to Mr.Jaggers's chair, being greasy with shoulders

its either analogy inference or paradox
i think its inference

Actually, the given statement describes a paradox. A paradox is a figure of speech that presents a seemingly contradictory or nonsensical statement, but upon closer examination, it reveals an underlying truth or meaning. In this case, the paradox lies in the description of the small room and the presence of greasy shoulders on the wall. The fact that the clients back up against the wall, causing it to become greasy, suggests that the small size of the room forces people to be in close proximity to each other. This paradox highlights the cramped and uncomfortable nature of the room and the crowded conditions experienced by the clients.
