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:
If smoking had died out at Oxford its decline must have been rapid. When a certain young John James was an undergraduate of Queen's, 1778 to 1781, he and his correspondents spoke severely of the "miserable condition of Fellows who (under the liberal pretence of educating youth) spend half their lives in smoking tobacco and reading the newspapers." About 1800 the older or more old-fashioned of the Fellows at New College, "not liking the then newly introduced luxury of Turkey carpets," says Mr. G.V. Cox, in his "Recollections of Oxford," 1868, "often adjourned to smoke their pipe in a little room opposite to the Senior Common-room, now appropriated to other uses, but then kept as a smoking-room." A Mr. Rhodes, a one-time Fellow of Worcester College, who was elected Esquire Bedel in Medicine and Arts in 1792, had a very peculiar way of enjoying his tobacco. Mr. Cox says: "On one occasion, when I had to call upon him, I found him drinking rum and water, and enjoying (what he called his luxury) the fumes of tobacco, not through a pipe or in the shape of a cigar, but burnt in a dish!"
