He begins by refuting a popular notion, that bohea and green tea are leaves of the same shrub, gathered at different times of the year.  He is of opinion, that they are produced by different shrubs.  The leaves of tea are gathered in dry weather; then dried and curled over the fire, in copper pans.  The Chinese use little green tea, imagining, that it hinders digestion, and excites fevers.  How it should have either effect, is not easily discovered; and, if we consider the innumerable prejudices, which prevail concerning our own plants, we shall very little regard these opinions of the Chinese vulgar, which experience does not confirm.

When the Chinese drink tea, they infuse it slightly, and extract only the more volatile parts; but though this seems to require great quantities at a time, yet the author believes, perhaps, only because he has an inclination to believe it, that the English and Dutch use more than all the inhabitants of that extensive empire.  The Chinese drink it, sometimes, with acids, seldom with sugar; and this practice our author, who has no intention to find anything right at home, recommends to his countrymen.

The history of the rise and progress of tea-drinking is truly curious.  Tea was first imported, from Holland, by the earls of Arlington and Ossory, in 1666; from their ladies the women of quality learned its use.  Its price was then three pounds a pound, and continued the same to 1707.  In 1715, we began to use green tea, and the practice of drinking it descended to the lower class of the people.  In 1720, the French began to send it hither by a clandestine commerce.  From 1717 to 1726, we imported, annually, seven hundred thousand pounds.  From 1732 to 1742, a million and two hundred thousand pounds were every year brought to London; in some years afterwards three millions; and in 1755, near four millions of pounds, or two thousand tons, in which we are not to reckon that which is surreptitiously introduced, which, perhaps, is nearly as much.  Such quantities are, indeed, sufficient to alarm us; it is, at least, worth inquiry, to know what are the qualities of such a plant, and what the consequences of such a trade.

He then proceeds to enumerate the mischiefs of tea, and seems willing to charge upon it every mischief that he can find.  He begins, however, by questioning the virtues ascribed to it, and denies that the crews of the Chinese ships are preserved, in their voyage homewards, from the scurvy by tea.  About this report I have made some inquiry, and though I cannot find that these crews are wholly exempt from scorbutick maladies, they seem to suffer them less than other mariners, in any course of equal length.  This I ascribe to the tea, not as possessing any medicinal qualities, but as tempting them to drink more water, to dilute their salt food more copiously, and, perhaps, to forbear punch, or other strong liquors.

He then proceeds, in the pathetick strain, to tell the ladies how, by drinking tea, they injure their health, and, what is yet more dear, their beauty.
