The grand entrance in front, which is to be reserved for the especial use of his Majesty and the Royal Family, will be composed of white marble, and will be a faithful model of the arch of Constantine, at Rome, with the exception of the equestrian figure of his Majesty George IV. on the top. The workmanship of this arch is expected to rival any thing of the sort in the kingdom, and to equal the finest works of antiquity. From each side of the arch a semicircular railing will extend to the wings, executed in the most beautiful style, in cast-iron, and surmounted by tips or ornamental spears of mosaic gold. The area, within, will consist of a grass-plat, in the centre of which will be an ornamental fountain, and the whole will be bounded by a graveled road. The wing on the left will comprise his Majesty's chapel, the kitchen, and other offices; and that on the tight, his Majesty's private suite of apartments. The entrance to the former is from the back, near to where Buckingham-gate formerly stood, and it is by this door that the visiters to the palace on gala days will be admitted. Passing through the building, they will enter a spacious colonnade, which extends along the front of the body of the palace, and in front of each wing; above the colonnade is a magnificent balcony, supported by columns of the Doric order. At the end of each wing is a pediment, supported by Corinthian columns. The entablature of each pediment is tastefully filled up with groups of figures in white marble, exquisitely carved in _alto relievo_, illustrative of the arts and sciences. On the extreme points of the wing on the left, are fixed statues representing History, Geography, and Astronomy; and on those of the right wing, Painting, Music, and Architecture. On the entablature of the pediment, in front of the main body of the palace, it is intended to place the Arms of England; and on the top are placed Neptune, with Commerce on one side, and Navigation on the other. Around the entire building, and above the windows, is a delicately worked frieze, combining in a scroll the Rose, the Shamrock, and the Thistle. The entrance-hall is about thirty-three feet in height. The pavement is of white marble slightly veined with blue. The entire hall is bordered with a scroll of Sienna or yellow, centred with rosettes of puce-coloured marble, inlaid in the most masterly style of workmanship. The walls are of Scagliola, and the ceiling is supported by a succession of white marble pillars. From the hall are the avenues leading to the state apartments--drawing-rooms, dining-rooms, throne-room, statue-gallery, picture-gallery, &c. * * * * * THE ANECDOTE GALLERY. * * * * * WINDSOR AS IT WAS.
