By this, as will be universally allowed, criticism is disarmed. The proportions of the room are admirable, and the lines of architecture full of grace and beauty. The lighting is based on the most scientific principles, and the dome itself (only inferior in dimensions to one other in existence) maintains its own appearance as to actual size, and is of grandeur proportionate to its general lightness and elegance. The spectator will, however, be most struck with its style of internal decoration, a grand example of success, when our attempts have hitherto been so futile. The fear of tampering with colour has ever been one of our idiosyncrasies, and it may be observed in this instance. True, that in our uncertain climate and obscure atmosphere, Nature herself lends but little aid in the matter, either as regards instruction or example; but the colouring of the Reading-Room may be pronounced free from indifference or conventionality, and to the freedom observable is added a boldness and originality which must be seen to be truly estimated at its proper value. To give the reader, however, some general notion of the manner in which the colouring has been managed, we quote, without apology, one more passage from the small _brochure_ to which we have alluded:— “In the decoration of the interior dome, light colours and the purest gilding have been preferred. The Great Room, therefore, has an illuminated and elegant aspect. The decorative work may be shortly described:—The inner surface of the dome is divided into twenty compartments by moulded ribs, which are gilded with leaf prepared from unalloyed gold, the soffites being in ornamental patterns, and the edges touching the adjoining margins fringed with a leaf-pattern scolloped edge. Each compartment contains a circular-headed window, twenty-seven feet high and twelve feet wide, with three panels above, the central one being medallion-shaped, the whole bordered with gilt mouldings and lines, and the field of the panels finished in encaustic azure blue, the surrounding margins being of a warm cream colour. The details of the windows are treated in like manner—the spandril panels blue; the enriched column and pilaster caps, the central flowers, the border moulding and lines being gilded—the margins cream colour throughout. The moulded rim of the lantern light, which is painted and gilded to correspond, is 40 feet in diameter. The sash is formed of gilt moulded ribs, radiating from a central medallion, in which the Royal Monogram is alternated with the Imperial Crown. “The cornice, from which the dome springs, is massive and almost wholly gilded, the frieze being formed into panels bounded by lines terminating at the ends with a gilt fret ornament. Each compartment of the dome is marked by a bold enriched gilt console, which forms at once the support of the main rib and the base for a colossal marble statue, a series of which it is proposed to place on the cornice.
