From Chapter 2:
Perhaps the most noteworthy thing about smoking at this period, from the social point of view, was its fashionableness. One of the marked characteristics of the gallant—the beau or dandy or "swell" of the time—was his devotion to tobacco. Earle says that a gallant was one that was born and shaped for his clothes—but clothes were only a part of his equipment. Bishop Hall, satirizing the young man of fashion in 1597, describes the delicacies with which he was accustomed to indulge his appetite, and adds that, having eaten, he "Quaffs a whole tunnel of tobacco smoke"; and old Robert Burton, in satirically enumerating the accomplishments of "a complete, a well-qualified gentleman," names to "take tobacco with a grace," with hawking, riding, hunting, card-playing, dicing and the like. The qualifications for a gallant were described by another writer in 1603 as "to make good faces, to take Tobacco well, to spit well, to laugh like a waiting gentlewoman, to lie well, to blush for nothing, to looke big upon little fellowes, to scoffe with a grace ... and, for a neede, to ride prettie and well."

From Chapter 8:
In the first two or three decades of the nineteenth century smoking reached its nadir. No dandy smoked. If some witnesses may be believed smoking had almost died out even at Oxford. Archdeacon Denison wrote in his "Memories"—"When I went up to Oxford, 1823-24, there were two things unknown in Christ Church, and I believe very generally in Oxford—smoking and slang"; but one cannot help fancying that the archdeacon's memory was not quite trustworthy. It is difficult to imagine that there was ever a time when the slang of the day was not current on the lips of young Oxford, or that so long as tobacco was procurable it did not find its way into college rooms.
