I have little left to say in this place respecting most of the critical subjects connected with the work, as I have entered at considerable length into the discussion of these matters in the Preliminary Discourse. It is proper, however, to acknowledge that I have derived great assistance from M. Littré’s excellent edition, of which the parts already published embrace all the treatises here given, with the exception of the last four. On all occasions I have freely availed myself of his labors, more especially in amending the text, in which respect his edition undoubtedly surpasses all those which preceded it. I have also not neglected to consult all the other standard editions, especially those of Foës, Van der Linden, and Kühn, and likewise, as will be seen, many other editions of separate treatises, so that, altogether, I trust it will be found that I have not often failed in attaining the true meaning of my author, as far as it can now be ascertained. I am aware, indeed, that, situated as I am, at a distance from public libraries, and deprived of personal intercourse with learned men of congenial pursuits whom I could consult in cases where I felt myself in doubt, I have labored under disadvantages which may render my work not so perfect in all respects as could have been wished; and that, by sending it to the press as soon as completed, it is not unlikely I may have left it disfigured by certain blemishes which _multa dies et multa litura_ might have enabled me to remove. But the urgency of my other professional and private concerns forbade me to devote much longer time to any one task, however interesting or important; while the weight of increasing years, and the confirmed conviction of the endless nature of literary research on such a subject as this, disposed me, on the present occasion, to keep in mind the solemn admonition of my Author, that “Life is short, and Art is long.” F.
