On arriving in front of the British Museum for the first time, the visitor will not fail to notice the Grecian Ionic facade, ornamented with forty-four columns, and rising at its extreme point to the height of sixty-six feet. The sculpture which decorates the tympanum of the portico is the work of Sir Richard Westmacott, and is an allegorical representation of the progress of civilisation. The spiritual influences that have successively worked upon the savage natures of the dark ages, have here distinct types. Religion tames the savage; Paganism makes him a crouching sensualist; the Egyptian sees a God in the stars of heaven; and then the mathematician, the musician, the poet, and the painter set to work, and these prophets of mysterious beauties realise civilised mankind. The visitor enters the museum, after ascending a noble flight of steps, by a massive carved oak door, into a fine entrance hall, the ceiling of which is highly coloured, and the general decoration of which is Grecian Ionic. Here he will observe, in addition to one or two of the Nineveh sculptures, at once, three statues: one of the aristocratic lady sculptor, the Honourable Mrs. Damer; Chantrey's statue of Sir Joseph Banks; and Roubillac's study of Shakspeare, presented to the museum by David Garrick. Before entering the galleries of the museum the visitor should observe, that the building faces the four points of the compass, and that the facade forms the southern line. This observation will facilitate a careful and regular examination of the interior. Branching westward from the entrance hall, then eastward to the gallery, is a noble flight of seventy steps, the walls of the staircase being richly inlaid with marble. Having ascended this staircase, the visitor's attention is at once arrested by two stuffed giraffes--the giraffe of North Africa, and the giraffe of South Africa, given to the museum by the late Earl of Derby. These striking zoological specimens at once introduce the visitor to THE SOUTHERN (CENTRAL) ZOOLOGICAL ROOM,
