In the numerous letters and papers which I have addressed during the last two years to the Secretary of the Royal Asiatic Society, and which have been either read at the meetings of the Society, or in some instances published in the Journal, I have explained, in more or less detail, the successive discoveries which I have made in the history of ancient Assyria. Those discoveries have pretty well established the fact that an independent empire was first instituted on the Upper Tigris in the thirteenth century, B.C. They have furnished what may be considered an almost complete list of Assyrian kings from the above-named period to the destruction of Nineveh in B.C. 625, and they have further made us acquainted with the general history of Western Asia, during this interval of above seven centuries.
