undertaken the office of his editor under the condition—that Mr. Stewart's writings should, in this collective edition, be published without note or comment. The only annotations, therefore, which I have deemed it necessary or even proper to append, are such as were required in the execution of my editorial functions. By exception, however, one or two bibliographical facts of some importance, but generally unknown, have been simply supplied. Where also Mr. Stewart had neglected a useful reference, such has been silently filled up; while verbal inaccuracies and imperfections have, in like manner, been emended. Beside, therefore, the principal value bestowed on this edition of the Dissertation by the extent and importance of its new matter; it is hoped, that the book has thus been rendered more convenient for study, to say nothing of the useful subsidiaries of a well digested Index, and of an appropriate disposition of minuter running titles.
