The valuable collections in the department of Natural History at present at the British Museum, the entire collection of the Museum of Economic Geology, the Trade Museum of the Society of Arts, the collection of patented inventions under the charge of the Patent Office, and possibly one or both of the private collections of the Regents Park and Surrey Zoological Gardens, if concentrated upon this spot, would form such a valuable and instructive collection, as could not fail to excite a great interest in the institution amongst all classes of the community. It is difficult to estimate what might be the ultimate cost of such an institution; but it is probable, I think, that much less than a million of money would cover the amount of it. This expenditure, however, might be spread over a course of years, and, as the institution would add so much to public enjoyment and instruction, and would be practically so advantageous to the arts, manufactures, and commerce of the country, Parliament would not be likely to be backward in voting from time to time the requisite supplies. Such an institution, when fully carried out, might then vie with the Jardin des Plantes, which it would much exceed in acreage, and the Conservatoire des Arts et Métiers of the French capital combined, and bear an honourable comparison with those noble institutions. THIRDLY. As regards the present National Gallery and Royal Academy of Art. The building containing these two Institutions occupies the finest position which London affords for architectural display, and is unfortunately the meanest and most ineffective of its public buildings. It stands upon rather more than an acre of ground, nearly one half of which is wasted in the Fore Court, under a mistaken notion that it was desirable to let in a view of the portico of St. Martin’s Church from Pall Mall East, which, owing to the tower of the church being now seen above it, has lost all the importance and grandeur of effect which it formerly had when seen from Old St. Martin’s Lane. The present edifice contains 278 squares of building, which I propose should be increased to 448 squares, by removing the present useless portico and other columns and projections which now break up its front, building upon the wasted portion of its site, namely the fore court, and placing the staircase on the site of the present sculpture-room. With these and other additions and alterations, assuming that the national pictures are removed, I propose that the building should be devoted exclusively to the teaching of Art in all its branches, and the periodical exhibition of modern works, for which purpose it should be divided between the Royal Academy of Fine Art, and the Metropolitan School of Design for practical and decorative Art.
