From Chapter 4:
We know also that the Roundhead soldiers smoked in circumstances that did them no credit. In the account of the trial of Charles I, written by Dr. George Bates, principal physician to his Majesty, and to Charles II also, we read that when the sentence of the Court presided over by Bradshaw, condemning the King "to death by severing his Head from his Body," had been read, the soldiers treated the fallen monarch with great indignity and barbarity. They spat on his clothes as he passed by, and even in his face; and they "blew the smoak of tobacco, a thing which they knew his Majesty hated, in his sacred mouth, throwing their broken Pipes in his way as he passed along."

From Chapter 8:
When Tennyson was an undergraduate at Cambridge, 1828-30, he and his companions all smoked. At the meetings of the "Apostles"—the little group of friends which included the future Laureate—"much coffee was drunk, much tobacco smoked." Dons smoked as well as undergraduates. At Queens', the Combination-room in Tennyson's time had still a sanded floor, and the "table was set handsomely forth with long 'churchwardens'"—as the poet told Palgrave when the two visited Cambridge in 1859. George Pryme, in his "Autobiographic Recollections," 1870, states that in 1800 "smoking was allowed in the Trinity Combination-room after supper in the twelve days of Christmas, when a few old men availed themselves of it," which looks as if tobacco were not very popular just then at Trinity. With the wine, pipes and the large silver tobacco-box were laid on the table. Porson, when asked for an inscription for the box, suggested Pryme says that among the undergraduates, of whom he was one, tobacco had no favour, and "an attempt of Mr. Ginkell, son of Lord Athlone ... to introduce smoking at his own wine-parties failed, although he had the prestige of being a hat-fellow-commoner."
