Your Committee will now proceed to consider the questions of the final enlargement and alterations of the present buildings, and of the redistribution of the augmented space for the several purposes above mentioned. In making the following proposals, your Committee have kept in view the principle that it would not be advisable for the Trustees to appropriate specifically to particular objects any particular space. They will, therefore, as much as possible, confine themselves to stating how the augmented space should be generally redistributed among the remaining collections, giving the chief place to the Antiquities and Library; the arrangement of the particular objects or classes of objects should rest on the responsibility of the head of each department, who would in due time submit his views to the Trustees. Your Committee also wish it to be clearly understood that the structural details herein suggested or implied, must be considered liable to such modifications as the farther development of the scheme may require. [Illustration: BRITISH MUSEUM. PLAN OF THE GROUND FLOOR. ] [Sidenote: NEW STAIRCASES.] In the building as now arranged, the principal staircase (No. 69 on the plan of the ground floor) is situated on the left in the Entrance Hall (No. 2); opposite to the entrance is the corridor (No. 80) leading to the Reading-Room; east and west of that corridor, between the main building and the new Library, there is an area (No. 70 and 79) about thirty feet wide unoccupied. It has long been suggested that the principal staircase should be removed from No. 69, and that two staircases be erected on the area 70 and 79, one on each side of No. 80. The hall entrance (No. 2) would be lighted by the skylight already existing in the roof, and by a corresponding opening to be made in the upper floor. The site of the principal staircase, No. 69, would be occupied by a large room, seventy-five feet by thirty-five, giving an area of two thousand six hundred and twenty-five feet, exactly like the one opposite to it (No. 58) in height as in every other respect, with a floor on a level with the rest of the building.
