What is now the real sense and the proper signification of those scientific primary lines among the Chinese, which exert an influence over the whole of their ancient literature, and upon which they themselves have written an incredible number of learned commentaries? Leibnitz supposed them to contain a reference to the modern algebraical discoveries, and especially to the binary calculation. Other writers, especially among the English, drawing their observations more from real life, remark on the other hand, that this ancient system of mystical lines serves at present the purpose of a sort of oracular play of questions, like the turning up of cards among Europeans, and is converted to many superstitious uses, especially for making pretended discoveries in alchymy, to which the Chinese are very much addicted. But this is only an abuse of modern times, which no longer understand this primitive system of symbolical signs and lines. The high antiquity of these lines and of the eight koua can be the less a matter of doubt as even mythology has ascribed them to the primitive Patriarch of the Chinese--Fohi, who is represented as having espied these lines on the back of a tortoise, and having thence deduced the written characters; which many of the learned Chinese wish to derive from these eight koua or combinations of the first symbolical lines. But the French scholar, whom I have more than once had occasion to name, and who is well able to form a competent opinion on the subject, is most decidedly opposed to this Chinese derivation of all the written characters from the eight koua; and it would appear, indeed, that the latter differ totally from the common system of Chinese writing, and must be looked upon as of a distinct scientific nature.
