From Chapter 1:
"Tarlton, as other gentlemen used, at the first comming up of tobacco, did take it more for fashion's sake than otherwise, and being in a roome, set between two men overcome with wine, and they never seeing the like, wondered at it, and seeing the vapour come out of Tarlton's nose, cryed out, fire, fire, and threw a cup of wine in Tarlton's face. Make no more stirre, quoth Tarlton, the fire is quenched: if the sheriffes come, it will turne to a fine, as the custome is. And drinking that againe, fie, sayes the other, what a stinke it makes; I am almost poysoned. If it offend, saies Tarlton, let every one take a little of the smell, and so the savour will quickly goe: but tobacco whiffes made them leave him to pay all."

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.
