From Chapter 2:
A curious feature of tobacco-manners among fashionable smokers of the period was the practice of passing a pipe from one to another, after the fashion of the "loving cup." There is a scene in "Greene's Tu Quoque," 1614, laid in a fashionable ordinary, where the London gallants meet as usual, and one says to a companion who is smoking: "Please you to impart your smoke?" "Very willingly, sir," says the smoker. Number two takes a whiff or two and courteously says: "In good faith, a pipe of excellent vapour!" The owner of the pipe then explains that it is "the best the house yields," whereupon the other immediately depreciates it, saying affectedly: "Had you it in the house? I thought it had been your own: 'tis not so good now as I took it for!" Another writer of this time speaks of one pipe of tobacco sufficing "three or four men at once."

From Chapter 5:
General Monk, to whom Charles II owed so much, is said to have indulged in the unpleasant habit of chewing tobacco, and to have been imitated by others; but the practice can never have been common.
