From Chapter 8:
In the whole sixteen volumes of Walpole's correspondence, as so admirably edited by Mrs. Toynbee, there is scarcely a mention of tobacco; and the same may be said of other collections of letters of the same period—the Selwyn letters, the Delany correspondence, and so on. Neither Walpole nor any member of the world in which he lived would appear to have smoked. In Miss Burney's "Evelina," 1778, from the beginning to the end of the book there is no mention whatever of tobacco or of smoking. Apparently the vulgar Branghtons were not vulgar enough to smoke. Such use of tobacco was considered low, and was confined to the classes of society indicated in the preceding chapter. One of the characters in Macklin's "Love à la Mode," 1760, is described as "dull, dull as an alderman, after six pounds of turtle, four bottles of port, and twelve pipes of tobacco."

From Chapter 13:
Another French visitor to our shores, M. Jorevin, whose rare book of travels was published at Paris in 1672, was wandering in the west of England about the year 1666, and in the course of his journey stayed at the Stag Inn at Worcester, where he found he had to make himself quite at home with the family of his hostess. He tells us that according to the custom of the country the landladies sup with strangers and passengers, and if they have daughters, these also are of the company to entertain the guests at table with pleasant conceits where they drink as much as the men. But what quite disgusted our visitor was "that when one drinks the health of any person in company, the custom of the country does not permit you to drink more than half the cup, which is filled up and presented to him or her whose health you have drunk. Moreover, the supper being finished, they set on the table half a dozen pipes, and a packet of tobacco, for smoking, which is a general custom as well among women as men, who think that without tobacco one cannot live in England, because, say they, it dissipates the evil humours of the brain."
