From Chapter 1:
So far Hariot's "Report" regarded tobacco from the medicinal point of view only; but it is important to note that he goes on to describe his personal experience of the practice of smoking in words that suggest the pleasurable nature of the experience. He says: "We ourselves during the time we were there used to suck it after their maner, as also since our returne, and have found maine [? manie] rare and wonderful experiments of the vertues thereof: of which the relation woulde require a volume by itselfe: the use of it by so manie of late, men and women of great calling as else, and some learned Physitians also, is sufficient witness."

From Chapter 8:
No doubt smoking had its ups and downs at the Universities apart from the set of the main current of fashion. We learn from the invaluable Gunning that at Cambridge about 1786 smoking was going "out of fashion among the junior members of our combination-rooms, except on the river in the evening, when every man put a short pipe in his mouth." "I took great pains," he adds, "to make myself master of this elegant accomplishment, but I never succeeded, though I used to renew the attempt with a perseverance worthy of a better cause." About the same time Dr. Farmer was Master of Emmanuel and the Master was an inveterate smoker. Gunning says that Emmanuel parlour under Farmer's presidency was always open to those who loved pipes and tobacco and cheerful conversation—a very natural collocation of tastes. Farmer's silver tobacco-pipe is still preserved in his old college, while Porson's japanned snuff-box is at Trinity.
