So many attempts have been made to restore the original chronology of Manetho from the list of kings which have been transmitted to us, on his authority, by Africanus, Eusebius, and others, that it will naturally be considered presumptuous in any one to make a new attempt. And yet, even as respects the new kingdom, the attempts that have been hitherto made, are very unsatisfactory; and we find them to be at variance both with the chronology of the Assyrian Inscriptions, of Ptolemy's Canon, and of the 2nd Book of Kings,—all of which are in perfect harmony with one another. Even so late as the 25th, or Ethiopian dynasty, we find Lepsius and Bunsen opposed to one another. The cause of all these failures,—for such I consider all the attempts at restoring the true chronology which have hitherto been made to be,—I believe to be an unsound method of criticising the lists that have come down to us; and I ascribe the success, which I flatter myself I have attained, to my proceeding in a way which, so far as I am aware, is wholly new.
