From Chapter 2:
Hentzner, the German traveller, who visited London in 1598, speaks of smoking being customary among the audience at plays, who were also supplied with "fruits, such as apples, pears and nuts, according to the season, carried about to be sold, as well as ale and wine." He was struck with the universal prevalence of the tobacco-habit. Not only at plays, but "everywhere else," he says, the "English are constantly smoking tobacco," and then he proceeds to describe how they did it: "They have pipes on purpose made of clay, into the further end of which they put the herb, so dry that it may be rubbed into powder; and putting fire to it, they draw the smoak into their mouths, which they puff out again through their nostrils, like funnels, along with it plenty of phlegm and defluxions from the head." This suggests that the unpleasant and quite unnecessary habit of spitting was common with these early smokers, a suggestion which is amply supported by other contemporary evidence.

From Chapter 7:
In Townley's well-known two-act farce "High Life Below Stairs," 1759, the servants take their masters' and mistresses' titles and ape their ways. The menservants—the Dukes and Sir Harrys—offer one another snuff. "Taste this snuff, Sir Harry," says the "Duke." "'Tis good rappee," replies "Sir Harry." "Right Strasburgh, I assure you, and of my own importing," says the knowing ducal valet. "The city people adulterate it so confoundedly," he continues, "that I always import my own snuff;" and in similar vein he goes on in imitation of his master, the genuine Duke. These servants copy the talk and style (with a difference) of their employers; but smoking is never mentioned. The real Dukes and Sir Harrys took snuff with a grace, but they did not do anything so low as to smoke, and their menservants faithfully aped their preferences and their aversions.
