Yet flattering as this extensive suffrage may seem, it is in reality rather mortifying to the Author; who finds, from the nature of the encomiums bestowed upon his performance, that it has been more generally liked than understood; and that, whilst a few have honoured it with a deliberate reading, and separated the substance from the vehicle in which it was contained, far the greater number have mistaken the mask for the reality, and considered it simply as a pleasing tale; as the mere recital of a traveller's observation; or, as the luxuriant effusions of a fertile imagination, a splendid picture of visionary excellence. Whether these misapprehensions arose from want of perspicuity in the writer, or want of attention in the readers, admits of no dispute; the former was most probably the case. The Author therefore, who wishes to be perfectly understood, and is more ambitious of being useful than entertaining, humbly begs leave to offer, at the end of this second edition, such reasons and explanations as seem necessary, either to remove doubts, or clear obscurities; he flatters himself they will be found sufficient, and serve to place the work in its true, its most advantageous light. Of these illustrations he saw the necessity some time ago, and framed them into a Discourse supposed to be pronounced by Chet-qua, then in England; judging it, at that time, a sort of propriety to put in the mouth of a Chinese, what farther information was wanted relative to his country. But as there is now no longer any necessity for disguise, both the Dissertation and Explanatory Discourse ought certainly to appear in their natural dress. To new-model them, however, would require more time than the Author can possibly spare; he therefore has republished the Dissertation, in its original form, and the Discourse as it was originally written; hoping the indulgent reader will pardon these defects, and gather the fruit, if there be any to gather, without minding the trees on which it grows. _Introduction._
