608 CYCLOPAEDIA a new and more dignified aspect. This edition of the "Encyclopaedia Britannica" was repub- lished in Philadelphia by Thomas Dobson (21 vols. 4to, including the supplement, 1798-1803). A fourth edition, increased to 20 vols., was completed in 1810, under the able superinten- dence of Dr. James Millar. This was enriched with the contributions of Prof. Wallace on pure mathematics. A fifth and a sixth edition soon followed, but were little more than reprints of the former. While these were in progress, a supplement extending to 6 vols. made its ap- pearance, edited by Macvey Napier, and pub- lished by Archibald Constable. The first half volume was produced in 1815, under the sanc- tion of the name of Dugald Stewart, as the author of the first of those preliminary disser- tations on the history of the sciences which, in a more complete state, so greatly adorn and recommend the later editions. Enriched as it was by contributions from the most eminent writers and scholars of the day, including the distinguished philosophers of France, Arago and Biot, the work rose rapidly in public favor. The copyrights of the previous editions having passed into the hands of A. and C. Black of Edinburgh, they immediately commenced the publication of an enlarged edition, under the editorial supervision of Prof. Napier (21 vols., including the later supplement, a general in- dex, and numerous engravings, 1830-'42). The eighth edition, with extensive improvements and additions, and an introductory volume of dissertations, was commenced in 1853, and published jointly by A. and 0. Black of Edin- burgh, and Little and Brown of Boston ; the concluding (21st) volume appeared in 1860. For this, as for the preceding editions, articles were furnished by the most distinguished con- temporary authors.
