As to the numerous eclipses taken notice of in the records of the country, they are mere registers, noted down whenever they happened, and not predictions or the result of calculations. It does not appear, indeed, that the Chinese were, at any time, able to predict an eclipse, notwithstanding all that has been said in their favour on this subject. The reputed Chinese tables, published by Father Couplet, have been detected to be those of Tycho Brahe; and Cassini found the chronology of their eclipses, published by Martinus, to be erroneous, and their returns impossible. It could not indeed be otherwise; the defectiveness of the calendar must necessarily falsify all their records as to time. Had the missionaries been disposed to confer a real service on the Chinese, instead of misleading the world by their strange and wonderful accounts of this people; instead of bestowing so much time in translating into Chinese a set of logarithm tables for the use of _Kaung-shee_, the second Emperor of the present dynasty, of which they pretend he was so fond that he always carried them about with him suspended to his girdle, they should rather have taught them the use, and the convenience, of the Arabic numbers, of whose combinations and results their own language is not capable, and have instructed a few of their youth in the principles of arithmetic and the mathematics. For such an omission, however, human nature can readily find an excuse. It would be too great an instance of self-denial, to relinquish the advantages and the credit which their superior skill had gained them over a vast empire, by making the individuals of that empire participate in their knowledge. When we reflect, for a moment, how many perplexities and difficulties were occasioned by the irregular coincidences of the solar and lunar periods, in the calendars of Europe, from the time of Julius Cæsar to the altering of the style by Pope Gregory, we may readily conceive how great must be the errors in the chronology of a country, where the inhabitants are entirely ignorant even of the first principles of astronomy, and where they depended on the adventitious aid of foreigners, to enable them to carry into execution one of the most important concerns of the government.
