From Chapter 4:
But to turn from this worthy Exeter citizen to more famous names: I do not know of any good evidence as to whether or not Cromwell smoked, although he is said to have taken an occasional pipe while considering the offer of the crown, but John Milton certainly did. The account of how the blind poet passed his days, after his retirement from public office, was first told by his contemporary Richardson, and has since been repeated by all his biographers. His placid day ended early. The poet took his frugal supper at eight o'clock, and at nine, having smoked a pipe and drunk a glass of water, he went to bed. Apparently this modest allowance of a daily evening pipe was the extent of Milton's indulgence in tobacco. He knew nothing of what most smokers regard as the best pipe of the day—the after-breakfast pipe.

From Chapter 6:
The attractions and the atmosphere of provincial coffee-houses were much the same as those of the London resorts. A German gentleman who visited Cambridge in July and August 1710 remarked that in the Greeks' coffee-house in that town, in the morning and after 3 o'clock in the afternoon, you could meet the chief professors and doctors, who read the papers over a cup of coffee and a pipe of tobacco. One of the learned doctors took the German visitor to the weekly meeting of a Music Club in one of the colleges. Here were assembled bachelors, masters and doctors of music of the University—no professionals were employed—who performed vocal and instrumental music to their mutual gratification, though, apparently, not to the satisfaction of the visitor, who records his opinion that the music was "very poor." "It lasted," he says, "till 11 P.M., there was besides smoking and drinking of wine, though we did not do much of either. At 11 the reckoning was called for, and each person paid 2s."
