In preparing for the press, after an interval of seven years, a second edition of this work, the author has found it unnecessary to make, excepting in two chapters, any important or exensive alterations.

The exceptions are the chapters on the History and Chronology of Chaldaea and Assyria.

So much fresh light has been thrown on these two subjects by additional discoveries, made partly by Sir Henry Rawlinson, partly by his assistant, Mr.George Smith, through the laborious study of fragmentary inscriptions now in the British Museum, that many pages of the two chapters in question required to be written afresh, and the Chronological Schemes required, in the one case a complete, and in the other a partial, revision.

In making this revision, both of the Chronology and the History, the author has received the most valuable assistance both from the published papers and from the private communications of Mr.
Smith--an assistance for which he desires to make in this place the warmest and most hearty acknowledgment.

He is also beholden to a recent Eastern traveller, Mr.A.D.Berrington, for some valuable notes on the physical geography and productions of Mesopotamia, which have been embodied in the accounts given of those subjects.
