I. By augmenting the contents of the page, without decreasing the size of the type, the Work, while much improved in appearance, will, notwithstanding the great extension of its matter, be comprehended in TWENTY Quarto Volumes, handsomely printed on paper of a superior quality; twenty volumes of the present being nearly equal to twenty-four of the former Editions. Each volume will consist of eight hundred pages, containing a much greater quantity of matter than any similar publication; and the Proprietors hold themselves distinctly PLEDGED to the Public, that the Work shall not, on any account, exceed TWENTY-ONE Volumes; their present confident belief, at the same time being, that it will be completed in TWENTY. II. The publication will proceed in THREE SHILLINGS PARTS, published every alternate week, Twelve of which Parts will form a volume; each Part thus averaging above sixty-six pages, and containing three and two Plates alternately. The First Part was published on the Twelfth of July 1834. As the printing of the whole will be finished long before the expiration of the period required for the periodical issue of the PARTS, the Subscribers will have the option of more speedily completing their copies of the Work, or of abiding by the publication in Parts till the end of the Series. III. Each Part will be sold for THREE SHILLINGS, thus making the price of a quarto volume, of eight hundred ample pages, only THIRTY-SIX SHILLINGS; a price very considerably lower than that of any similar publication of the day, and which, when the quantity of Matter in each volume, the quality of Paper and Printing, the numerous Engravings, and the ability of the Articles, are taken into account, must be allowed to place the Work in a highly advantageous point of view, even at a period when the modes of diffusing useful knowledge at a moderate expense have so justly engaged the attention of the Public. Considering its Extent and Execution, it will unquestionably form the cheapest, as well as the most valuable Digest of Human Knowledge that has yet appeared in Britain.
