From Chapter 4:
It seems likely that Richard Cromwell was a smoker. In 1689, long after he had retired into private life and had ample leisure for blowing clouds, he sent to a friend a "Boxe of tobacco," which was described as "A.J. Bod (den's) ... best Virginnea." In a letter to his daughter Elizabeth, dated 21 January 1705, there is a reference to this same dealer, whom he describes as "Adam Bodden, Bacconist in George Yard, Lumber [Lombard] Street." The allusion is worth noting as a very early instance of the colloquial trick of abbreviation familiar in later days in such forms as "baccy" and "bacca" and their compounds.

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."
