From Chapter 3:
Some of the apothecaries whose shops were in most repute for the quality of the tobacco kept, took pupils and taught them the "slights," as tricks with the pipe were called. These included exhaling the smoke in little globes, rings and so forth. The invaluable Ben Jonson, in the preliminary account of the characters in his "Every Man out of his Humour," 1600, describes one Sogliardo as "an essential clown ... yet so enamoured of the name of a gentleman that he will have it though he buys it. He comes up every term to learn to take tobacco and see new motions." Sogliardo was accustomed to hire a private room to practise in. The fashionable way was to expel the smoke through the nose. In a play by Field of 1618, a foolish nobleman is asked by some boon companions in a tavern: "Will your lordship take any tobacco?" when another sneers, "'Sheart! he cannot put it through his nose!" His lordship was apparently not well versed in the "slights."

From Chapter 6:
Even children seem to have smoked sometimes in the coffee-houses. Ralph Thoresby, the Leeds antiquary, tells a strange story. He declares that, one evening which he spent with his brother at Garraway's Coffee-house, February 20, 1702, he was surprised to see his brother's "sickly child of three years old fill its pipe of tobacco and smoke it as audfarandly as a man of three score; after that a second and a third pipe without the least concern, as it is said to have done above a year ago." A child of two years of age smoking three pipes in succession is a picture a little difficult to accept as true. As this is the only reference to tobacco in the whole of his "Diary," it is not likely that Thoresby was himself a smoker.
