SUPPLEMENT

TO THE

FOURTH AND FIFTH EDITIONS

OF THE

ENCYCLOPEDIA BRITANNICA.

EDINBURGH;

PRINTED FOR ARCHIBALD CONSTABLE AND CO. EDINBURGH ; GALE AND FENNER, LONDON; THOMAS WILSON AND SONS, YORK; ROBINSON, SON, AND HOLDSWORTH, LEEDS; JOHN RODFORD, HULL; AND JOHN CUMMING, DUBLIN.

THE ENCYCLOPEDIA BRITANNICA forms a General Dictionary, not only of Arts and Sciences, but of every branch of Human Knowledge. Its Plan has received the decided approbation of the most competent judges, particularly for its superior method of "rrangement in regard to the Sciences; and the publication of

Five extensive Editions must be allowed to afford a very satisfactory proof of the favourable opinion of the Public at large.

The Fifth Edition, which contains a greatly improved set of Engravings, has just been completed in Twenty Volumes Quarto ; and it is the object of the present Work, To supply all material omissions to continue the Historical and Biographical, as well as the Geographical and Statistical information to the present times-and to exhibit the Arts and Sciences in their latest state of improvement. As the Fifth was reprinted without any material variation from the Fourth Edition, this SUPPLEMENT will of course be equally applicable to both; but though more immediately connected with these Two Editions, it must also prove a valuable sequel to the Third.

The utility of such an addition, to a Work in so many hands, as the ENCYCLOPEDIA BRITANNICA, must indeed appear abundantly obvious; but the Publishers beg farther to mention, that this SUPPLEMENT is arranged upon a Plan, by which it will, within itself, afford a comprehensive view of the progress and present state of every department of Human Knowledge.

It will consist of Five Volumes, similar in size to those of the principal Work, and will be illustrated with numerous Engravings, executed in the best style of the art. The publication will proceed by Parts, or Half Volumes, to follow each other at as short intervals as the nature of the undertaking will permit.

To the first Half Volume there is prefixed a Dissertation, exhibiting a general view of the progress of Metaphysical, Ethical, and Political Philosophy, since the revival of Letters in Europe, by Mr DUGALD STEWART; and the second Volume will be prefaced with a similar view of the progress of Mathematical and Physical Science, by PROFESSOR Playfair.
