In the third century B.C., one of the emperors conceived the mad scheme of destroying all existing records, and writing a new set of annals in his own name, in order that posterity might consider him the founder of the empire. Sixty years after this barbarous decree had been carried into execution, one of his successors, who desired as far as possible to repair the injury, caused these books to be re-written from a copy which had escaped destruction. 9. SCIENCE, HISTORY, AND GEOGRAPHY.--Comparing the scientific development of the Chinese with that of the Western world, it may be said that they have made little progress in any branch of science. There are, however, to be found in almost every department some works of no indifferent merit. In mathematics they begin only now to make some progress, since the mathematical works of Europe have been introduced into their country. Astrology still takes the place of astronomy, and the almanacs prepared at the observatory of Peking are made chiefly by foreigners. Books on natural philosophy abound, some of which are written by the emperors themselves. Medicine is imperfectly understood. They possess several valuable works on Chinese jurisprudence, on agriculture, economy, mechanics, trades, many cyclopaedias and compendia, and several dictionaries, composed with extraordinary skill and patience. To this department may be referred all educational books, the most of them written in rhyme, and according to a system of intellectual gradation. The historical and geographical works of China are the most valuable and interesting department of its literature. Each dynasty has its official chronicle, and the celebrated collection of twenty-one histories forms an almost unbroken record of the annals from, the third century B.C. to the middle of the seventeenth century, and contains a vast amount of information to European readers. The edition of this huge work, in sixty- six folio volumes, is to be found in the British Museum. This and many similar works of a general and of a local character unite in rendering this department rich and important for those who are interested in the history of Asiatic civilization. "The General Geography of the Chinese Empire" is a collection of the statistics of the country, with maps and tables, in two hundred and sixty volumes. The "Statutes of the Reigning Dynasty," from the year 1818, form more than one thousand volumes. Chinese topographical works are characterized by a minuteness of detail rarely equaled.
