From Chapter 2:
The rich young gallant carried about with him his tobacco apparatus (often of gold or silver) in the form of tobacco-box, tobacco-tongs—wherewith to lift a live coal to light his pipe, ladle "for the cold snuffe into the nosthrill," and priming-iron. Sometimes the tobacco-box was of ivory; and occasionally a gallant would have looking-glass set in his box, so that when he took it out to obtain tobacco, he could at the same time have a view of his own delectable person. When our gallant went to dine at the ordinary, according to the custom of the time, he brought out these possessions, and smoked while the dinner was being served. Before dinner, after taking a few turns up and down Paul's Walk in the old cathedral, he might look into the booksellers' shops, and, pipe in mouth, inquire for the most recent attack upon the "divine weed"—the contemporary tobacco literature was abundant—or drop into an apothecary's, which was usually a tobacco-shop also, and there meet his fellow-smokers.

From Chapter 8:
smoking had certainly not died out at Cambridge, even at the time when Denison was at Oxford. According to the "Gradus ad Cantabrigium," 1824, the Cambridge smart man's habit was to dine in the evening "at his own rooms, or at those of a friend, and afterwards blows a cloud, puffs at a segar, and drinks copiously." The spelling of "segar" shows that cigars were then somewhat of a novelty.
