Twelve statues or busts between the columns, and perhaps a large sculpture in the centre, would be the natural complement of the room. The wall-space behind the columns would not be available for sculpture. The total accommodation in the three rooms would amply suffice for our present collection, even somewhat enlarged. [Sidenote: MEANS OF FUTURE ENLARGEMENT.] As it increased, however, further space might be obtained by erecting in the first and third rooms transverse walls, opposite the alcoves in the Roman galleries, thus subdividing the first room into three principal compartments, with a small lobby at each end, and the third into three compartments (of which the most northern would need some modification), with a lobby at the south end. The doorways through these walls might be twelve feet wide, so as to preserve the continuous appearance of the suite; and they would still leave one hundred and twelve feet of additional wall-space in the first room, and eighty-four in the third. The lighting would be somewhat improved by such an alteration. [Sidenote: WESTERN GALLERIES.] The last suite of galleries on the ground floor would contain the Roman and Phœnician remains. To avoid any obscuration from the houses on the west side of Charlotte Street, the windows should be as high in the wall as possible, and as broad as architectural propriety would admit, whilst the rooms should be not less than twenty-five feet high. [Sidenote: FIRST ROMAN ROOM.] XXXIX. _First Roman Room_, one hundred and ten feet by twenty-eight, exclusive of the alcoves.—It would contain mosaics, including those from Carthage, and miscellaneous sculptures, altars, architectural fragments, &c.; the mosaics indifferently placed on all sides of the room, the sculptures on the east side and against the two end walls.
