3. _Gallery of the Rotunda._—From one hundred and eighty to one hundred and ninety feet in circumference, and about nine feet wide. The powerful light from the centre of the dome would be favourable to terracotta statuettes and bas-reliefs, which could all be contained in shallow wall-cases, that would not materially narrow the gangway.[48] The Townley Collection of bas-reliefs, now in the Second Vase Room, might be arranged in panels all round, so as to produce a decorative effect, agreeable to their original destination. [Sidenote: ACCOMMODATION FOR TERRACOTTAS.] The entire space provided in these two rooms is much more than our terracottas can absolutely require; but this will facilitate an ornamental arrangement of the collection, appropriate to the character of the larger room. The small spaces between the Rotunda and the main building would serve for closets. [Sidenote: GLASS ROOM.] 4. _Glass Room_, twenty-eight feet by twenty-six.—The fittings proper for glass being different from those of terracottas, it is desirable to give it a separate room. This should be similarly arranged to the Vase Gallery, with wall-cases eight feet high, and table-cases in the centre. [Sidenote: BRONZE GALLERY. ITS ACCOMMODATION.] 5. _Bronze Gallery_, three apartments united; together eighty-two feet by twenty-eight.—As the advantage of a skylight for the bronze statuettes is necessarily sacrificed by the adoption of an upper floor, it would be best to place them, as far as possible, against each side of the transverse projections, separating those sides by internal partitions, and employing some contrivance to protect the bronzes from the cross light of the further windows, an arrangement possible with small objects in glass cases, though not with large statuary. In the middle of the gallery might be table-cases, placed longitudinally, or important objects on pedestals. The increase of accommodation in the Bronze Gallery, as in the Vase Gallery, is more than proportionate to the increase of space. Though the superficial area is only two thousand two hundred and ninety-six feet, in lieu of our present quantity, two thousand and twenty-one, the extent of wall-cases, which now is only one hundred and thirty-eight feet, would, even allowing doorways of twelve feet wide between each of these compartments, be increased to two hundred and fifty feet, equivalent, after allowing for the difference in height of the cases, to two hundred feet. This, if the Etruscan bronzes were transferred as already suggested, would liberally provide for the Greek and Roman Collection. [Sidenote: SECOND FLOOR OF NEW BUILDINGS FOR ANTIQUITIES.]
