     The cornice only is carried around the room at the ceiling, and in the staircase hall only the cymatium and corona of the cornice; but over the archway, supported by a colonnade of four fluted round columns, a complete entablature with nicely worked classic detail is employed and given added emphasis by several inches' projection into the reception hall.
