From Chapter 3:
Sometimes coltsfoot was mixed with tobacco. Ursula, the pig-woman and refreshment-booth keeper in Bartholomew Fair, in Ben Jonson's play of that name, says to her assistant: "Threepence a pipe-full I will have made, of all my whole half-pound of tobacco and a quarter of a pound of coltsfoot mixt with it too to eke it out."

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.
