Their beavers are smoothly brushed, and their boots well polished; all their appointments are tidy; they look the respectable walking gentleman to perfection.

They are prone to habits,--they frequent reading-rooms,--insurance-offices,--they walk the same streets at the same hours,--so that one becomes familiar with their faces and persons, as a part of the street-furniture.
There is one curious circumstance, that all city-people must have noticed, which is often illustrated in our experience of the slack-water gentry.

We shall know a certain person by his looks, familiarly, for years, but never have learned his name.

About this person we shall have accumulated no little circumstantial knowledge;--thus, his face, figure, gait, his mode of dressing, of saluting, perhaps even of speaking, may be familiar to us; yet who he is we know not.

In another department of our consciousness, there is a very familiar name, which we have never found the person to match.
