some well-known instances are placed wider apart than is ordinarily the case, and the space between is then occupied by a narrow panel.

In smaller apartments the pilaster may be dispensed with, but the division of the wall surface can conform to the same general plan both vertically and horizontally. In the absence of pilasters the spaces may be divided into panels alternately narrow and wide.
Ceilings
When the ceiling is divided the dividing ribs or beams should bear some relation to the general construction, though in the past this rule has not always been strictly adhered to. For example, the ceiling may very desirably be divided into equal squares or rectangles by means of wooden or plaster mouldings, leaving the enclosed spaces plain or decorated. When mouldings are used these may be enriched, but contrast should be maintained between the framing ribs and the panels.
