The call for a second edition of my Manual imposes upon me an obligation to supply the deficiencies of my former work. Corrections have been carefully made, and many parts completely re-written. A select list of books which treat of the respective departments of my subject is now first added; the former edition containing only references to the sources from which my facts were derived. This, I trust, will be considered an essential service to the friends of historical science, more especially the young, for whom and not for the learned these additions have been made. Their use in this place is particularly obvious, where it is in every one's power to procure the books referred to[b]. The short criticisms subjoined, where it seemed necessary, will serve as guides for their use. In the author's department of the work but little has been changed, while its form and appearance have been improved by the use of different types, by more accurate running titles, and by ranging the dates in the margin. By the adoption of the latter method the increase in the number of pages is rendered inconsiderable, notwithstanding the numerous additions which have been made to the matter. In its arrangement, this work is the same as my Manual of the History of the European States and their Colonies. Beyond this, however, these works have no relation to each other, but have been executed upon quite different principles; the present as a history of the _separate_ states of the ancient world, and the other as a general history of modern states and their colonies, as forming altogether one political system. Each, however, forms a complete work in itself, and it is by no means my intention to fill up the gulf which time has placed between them. [b] [The author alludes to the public library at Goettingen. TR.] I regret that the acute researches of M. Volney[c], upon the chronology of Herodotus before the time of Cyrus, came too late into my hands to be made use of in its proper place in my second edition. In the third this has been done. I lay claim, at the same time, to the thanks of the reader for giving, in an Appendix, the results of these researches, together with references to the passages by which they are supported; leaving out, however, all extraneous matter, and everything that cannot be proved by the positive assertions of the father of history.
