No. 14 and 18 are the two Elgin Rooms, containing the finest reliques of Greek art in existence, which have remained unarranged for years, owing to the difficulties which the space hitherto available presented for their definitive arrangement, and to the uncertainty of the final appropriation of the space No. 31. It seems, however, to be generally admitted that on the unoccupied plot of ground, No. 31, a continuation of the second Elgin Room should be erected of the same width, to include the Print Room, the floor of which should be lowered to the general level of the Museum ground floor, and its width extended westward about seven feet. Another gallery might thus be formed altogether four hundred and seventy-five feet long and thirty-seven wide. Should it not extend farther than the southern extremity of the first Elgin Room (No. 14), its length would be three hundred and thirty feet. The plot of ground, No. 32, ought also to be applied to the accommodation of Antiquities. The study No. 23 should be done away with. [Sidenote: ALTERATION OF STAIRCASE, NO. 27.] The two lower flights of the N.W. staircase, No. 27, should be taken down and reconstructed in No. 26 and 36, with the necessary alterations to reconnect them with the two upper flights, which would remain as they are now. The studies No. 28, and passage No. 29, should be cleared away, as well as those above them, together with the lower part of the western wall of No. 27, the southern wall of that space being continued to No. 30, thus forming a passage or gallery, about twenty-two feet wide, for communication between the Northern Egyptian Gallery and the new gallery to be erected at the north of the Elgin Rooms. From the new passage thus formed there should be an opening on the south side, and a flight of steps to descend to the gallery which is to be built on No. 32. There would be room under the new staircase, in the space No. 36, to form an additional study for the Printed Book Department, where it is much wanted. Upon No. 32, a gallery should be erected from the basement, like the Assyrian Gallery, No. 15, to both of which access might be had by two handsome staircases, descending north and south of No. 19, from which it is taken for granted the Phigaleian Marbles and other objects, now there, would be removed, the central space being applied to better purposes. [Illustration: BRITISH MUSEUM. PLAN OF THE GROUND FLOOR. WITH THE PROPOSED ALTERATIONS. ] It does not appear to your Committee that any farther accommodation for Antiquities can be procured on the ground floor, without interfering with rooms now appropriated to the Library. [Sidenote: NEW GALLERY ON NO. 32, LIKE ONE NOW ON NO. 13.]
