Footnote anchors are denoted by [number], and the footnotes have been placed at the end of the book. There is one large very wide table on page 24 of the original book. This has been split into six parts, with the first column replicated for readability. It is best viewed with a monospace font. The two footnotes specific to this table have been placed under the table, as in the original book, and are marked by † and ‡. The list of Plates in the original book, and in this etext, is at the end of the book. There are frequent abbreviated references to Kæmpfer’s Amœnitatum Exoticarum (Amœn. Exot. and similar). Changes to the text are noted at the very end of the book. [Illustration: Green Tea Fig. 1 to Fig. 17 Painted & Engraved by J. Miller. Publish’d according to Act of Parliament Dec. 10th 1771.] THE NATURAL HISTORY OF THE TEA-TREE, WITH OBSERVATIONS ON THE MEDICAL QUALITIES OF TEA, AND ON THE EFFECTS OF TEA-DRINKING. A NEW EDITION. BY JOHN COAKLEY LETTSOM, M. D. _LONDON._ PRINTED BY J. NICHOLS; FOR CHARLES DILLY. 1799. ADVERTISEMENT. In the year 1769 was printed an inaugural dissertation, intituled, “Observationes ad vires Theæ pertinentes.” In the year 1772 was published, “The Natural History of the Tea tree, with Observations on the Medical Qualities of Tea, and Effects of Tea-drinking,” which not only contained a translation of the Thesis, but likewise the natural history of this vegetable, and which having been long out of print, it was thought a second edition would be favourably received by the publick. In Sir George Staunton’s Embassy to China, lately published, there are some remarks on Tea, which are occasionally referred to in the present edition; and they are referred to with the satisfaction of confirming the relation first offered to the publick in 1772.
