THE MIRROR OF LITERATURE, AMUSEMENT, AND INSTRUCTION. No. 494.] SATURDAY, JUNE 18, 1831. [Price 2d. [Illustration.] EXETER HALL, STRAND. We rejoice to see the site of Burleigh House partly occupied by the above Building. Its object is to afford accommodation for the meetings of Philanthropic Societies--so that whatever may be the olden celebrity of the spot, it is reasonable to expect that its present appropriation will be associated with the most grateful recollections. This building is, perhaps, the most perfect erection of its kind in England. The approach from the Strand is remarkably modest: it is by a very narrow, though very chaste, door-way, situated between two Corinthian columns and pilasters. Within the door is a hall, with two flights of steps, which afterwards unite, and lead up to the entrance of the great hall itself; the hall below leads into a broad passage, which extends to the farther extremity of the building, opening right and left into various offices. On entering the door of the great hall, a vast and splendid room is presented to view, with scarcely a single interruption to the eye throughout its whole extent, capable of containing, with comfort, more than 3,000 persons. The floor is covered with substantial oak seats, equal to the accommodation of 2,500 persons. The greater portion of these are situated on a gentle rise, to permit a perfect view of the platform on which the proceedings take place. The platform is raised about six feet from the floor, and extends the whole breadth of the room, curving inwards, the extremities bending towards the audience: it contains seats for nearly 300 individuals. Behind this gallery again, are very capacious recesses, which will hold from three to four hundred persons. The lower part of the walls of the room is quite plain, the architect, probably, regarding the audience as a sufficient ornament in that quarter, though the rising of the seats would obscure carved-work if it were there. The windows are at a considerable height from the ground, and are of dimmed glass, with a chaste and classical border. The ceiling, which is at a noble height, is beautifully laid out in squares, with borderings and rosettes. An oblong opening occurs in the centre, with massive beams stretching across, presenting to view an erection in the roof, a form of construction, probably, necessary to so immense a mass of roofing, and serving also for the purposes of ventilation, as it contains windows at each end. There are four pillars near the end of the hall, rising to the ceiling, the capitals of which, as also those of some pilasters at the upper extremity of the hall, are exquisitely carved in straw-coloured marble. Behind the platform are numerous and convenient committee-rooms. The word "Philadelpheion," which may be rendered "loving brothers," is carved in Greek capitals over the entrance in the Strand.[1]
