When sickness invaded, and remedies were needed, the sovereign tasted the various plants to ascertain their cooling and tranquillizing properties, and in one day discovered seventy kinds of poisonous shrubs, with their antidotes, which he described in a book; and the science of medicine began to flourish. Since then, the Chinese have published a very compendious work on botany, called the Pun-tsaou, which is certainly the result of much labour, and, considering their disadvantages, does them great credit.

To the science of medicine the Chinese have paid some attention; but, as usual, were more celebrated for it in former than in latter times. The systems of their
