From Chapter 2:
Ben Jonson has given us an amusing picture of the behaviour of gallants on the Elizabethan stage, in his "Cynthia's Revels." In this scene a child thus mimics the obtrusive beau: "Now, sir, suppose I am one of your genteel auditors, that am come in (having paid my money at the door, with much ado), and here I take my place, and sit downe. I have my three sorts of tobacco in my pocket, my light by me, and thus I begin. 'By this light, I wonder that any man is so mad, to come to see these rascally tits play here—they do act like so many wrens—not the fifth part of a good face amongst them all—and then their musick is abominable—able to stretch a man's ears worse than ten—pillories, and their ditties—most lamentable things, like the pitiful fellows that make them—poets. By this vapour—an't were not for tobacco—I think—the very smell of them would poison me, I should not dare to come in at their gates. A man were better visit fifteen jails—or a dozen or two hospitals—than once adventure to come near them.'" And the young rascal, who at each pause marked by a dash had puffed his pipe, no doubt blowing an extra large "cloud" when he swore "by this vapour," turns to his companions and says: "How is't? Well?" and they pronounce his mimicry "Excellent!"

From Chapter 6:
Other well-known men of the late seventeenth century were "tobacconists" in the old sense of the word. Sir Isaac Newton is said to have smoked immoderately; and a familiar anecdote represents him as using for the purposes of a tobacco-stopper, in a fit of absent-mindedness, the little finger of a lady sitting beside him, whom he admired, but the truth of this legend is open to doubt. Thomas Hobbes, who lived to be ninety (1588-1679), was accustomed to dine at 11 o'clock, after which he smoked a pipe and then lay down and took a nap of about half an hour. No doubt he would have attributed the length of his days to the regularity of his habits. Izaak Walton, who also lived to be ninety, as the lover of the placid and contemplative life deserved to do, loved his pipe, though he seldom mentions smoking in the "Compleat Angler." Sir Samuel Garth, poet and physician, once known to fame as the author of "The Dispensary," was another pipe-lover, as is shown by his verses quoted at the head of this chapter. Dudley, the fourth Lord North, began to smoke in 1657, and, says Dr. Jessopp, "the habit grew upon him, the frequent entries for pipes and tobacco showing that he became more and more addicted to this indulgence. Probably it afforded him some solace in the dreadful malady from which he suffered so long."
