Much of the interest connected with the investigation of the Chinese and its cognate tongues, arises from the immense multitudes which speak and write them; and from the influence which China has, through the writings of her sages, exerted over the minds and progress of her neighbors. There is nothing like it in European history; but the spell cast over the intellects of the millions in eastern Asia, by the writings of Confucius, Mencius, and their disciples, is likely erelong to be broken by the infusion of Christian knowledge, the extension of commerce, and a better understanding of their political and social rights by the multitudes who now adopt them. For much of the information embraced in this memoir on China, Japan, and the adjacent countries, I am indebted to the Chinese Repository, (a monthly journal printed at Canton), and more especially to one of its accomplished editors, Mr. S. Wells Williams. This gentleman during a residence of twelve years in China, has made himself familiar with the written and spoken language of the Chinese, and is ranked, by some of the eminent Sinologists of Europe, among the profoundest adepts in that branch of literature and philology. Mr. Williams has also studied the Japanese language, which he reads and speaks; and is probably the only man in America familiar with the languages of China and Japan. Several natives of Japan, driven by adverse winds from their native shores, found their way to China, and were subsequently taken by an American ship to Yedo, but were not permitted to land. From these men, Mr. Williams has learned the spoken Japanese, and as much of the written language as they could impart. This gentleman is at present in New York making arrangements for getting founts of Chinese, Japanese, and Manchu type, for printing in these languages. The Chinese Repository is a monthly journal, printed at Canton, and is edited by the Rev. Dr. Bridgman and Mr. Williams. It contains much valuable information relating to China, Japan, and the eastern Archipelago, and frequently memoirs, translated from the Japanese and Chinese. On the whole, it may with truth be said to embody more information than any other work extant, on these countries. Mr. Williams has now in press a new work on the Chinese empire, which will contain an account of its general political divisions, including Manchuria, Mongolia, Ili and Tibet, their geographical and topographical features. The natural history of China; its government, laws, literature, language, science, industry and arts. Social and domestic life--History and Chronology--Religion; Christian missions; intercourse with other nations; and a full account of the late war with England.
