Dreams, waking visions, even ghosts, are as much a part of this world as are the buildings, bridges, and canals of Petersburg; the line dividing the outer from the inner, the solid from the fantasmagorical, wavers. This is a fluid world, full of coincidences, chance but fatal meetings, crucial words accidentally overheard, embodied in the communicating streets and squares, the adjoining rooms and apartments

Here a possible definition is the length of the shortest wet curve from source to mouth. This aspect of the river problem recurs in the notion of length of seacoast, and can there

This involved the increasing use of devices—some new, some perhaps adaptations from the Islamic world—such as banks, letters of credit, and bills of exchange.
