It is proposed to publish, in 20 Monthly Parts, this very important work, to contain 180 plates and 800 pages of letterpress description of the Public Buildings of London. Each Part will contain 9 plates and 40 pages of text, Price 2_s._ 6_d._, to be ready for delivery on the Magazine day of each month, beginning with (December 31, 1848) January 1, 1849. To the Architect, Builder, the Student in Architecture, and the Amateur, this desirable work for professional use and study is offered at an extremely small charge, and published at such intervals as to be convenient for all classes, entitled ILLUSTRATIONS OF THE PUBLIC BUILDINGS OF LONDON: Originally edited by the late AUGUSTUS PUGIN, JOS. GWILT, BRITTON, and others. NEWLY EDITED AND ENLARGED BY W. H. LEEDS. Manifold as are the publications which represent the various structures of the metropolis, this is the only work which describes them, not _ad libitum_, in views which, even when perfectly correct, show no more than the general aspect and locality of each building from a certain point, and consequently afford no information beyond mere external appearance—but exhibits them _architecturally_ by means of plans, elevations, and occasionally both sections and interior perspective views. Thus a far more complete and correct knowledge may be obtained of each edifice, in its entire arrangement in all its parts and dimensions, than by pictorial views of them. As studies for the Architect, the subjects contained in these volumes strongly recommend themselves,—more particularly so, as of the majority of them no plans and elevations are to be met with in any other publication, which materially enhances the interest of this collection, and it preserves to us authentic and tolerably complete records of many buildings which no longer exist. Among these are CARLTON HOUSE, illustrated with several plates, including sections, and a plan of the private apartments; the late ENGLISH OPERA HOUSE; MR. NASH’S GALLERY, which has since been dismantled of its embellishments; THE ROYAL EXCHANGE, and the BOARD OF TRADE. Among the new subjects introduced in this new edition will be found:—The New Plan and Elevation of the BRITISH MUSEUM—NEW HOUSES OF PARLIAMENT—ROYAL EXCHANGE—ARMY AND NAVY CLUB—NEW CONSERVATIVE CLUB—REFORM CLUB—MUSEUM OF ECONOMIC GEOLOGY—MANSION OF THE EARL OF ELLESMERE (Bridgewater House); together with several Plans of Basements, showing kitchens and domestic offices, and conveniences not hitherto given. List of Plates and short abstract of Subjects.
