It is the leading purpose of the Hakluyt Society to deal with the Archaeology of Geography, and more especially so in connexion with the progress made by our own English ancestors in the advancement of that important science. In pursuance of that object, therefore, Mendoza's account of China has been selected for re-publication, as being the earliest _detailed_ account of that country ever published in the English language. We say _detailed_ account, because we must not omit to mention that it was preceded by a short but interesting document, published by Richard Eden in his _History of Travayle in the West and East Indies_, entitled "Reportes of the Province of China," of the history and contents of which we shall hereafter speak in its proper place. While, however, in the selection for re-publication, respect is paid to the earliest narratives which appeared in our own tongue, the reader's appreciation of the subject is best secured by an introductory notice of all the antecedent descriptions which may at intervals have appeared in other languages. This plan is more especially desirable with respect to those earlier glimmerings of information which Europe obtained respecting a country so removed from the civilized world, by its geographical position and ethnological peculiarities, as China, yet so marvellously in advance of it at the times of which we speak, both in its intellectual and moral developments. In such notice, meanwhile, we propose to pass by all discussion as to the much disputed question of the position of the Thinae of Eratosthenes, Strabo, and the Periplus of the Erythraean Sea, or of the application of Marinus's Serica, as preserved to us by Ptolemy, to the kingdom of China. Upon these more uncertain data we shall dwell no longer than to state, that our own impression agrees with that of Vossius, that China is the country referred to, and that the Seres of Ammianus Marcellinus, corresponding as they so closely do in character with the modern Chinese, were intended to represent that people. That the Romans possessed some knowledge of China, would seem to be shown by a discovery made by the learned De Guignes, of a statement in a Chinese historical work, that in the year of our Lord 166, an embassy, said to have come by sea, arrived from An-thon (Antoninus) to the Emperor Yan-hi; and the use of the "serica vestis", alluded to by Horace and Propertius, would appear to confirm the impression, provided only that silk, and not muslin, were the commodity really alluded to.
