From Chapter 3:
Thomas Dekker, to whose pictures of London social life at the opening of the seventeenth century we are so much indebted for information both with regard to smoking and in respect of many other matters of interest, was himself an enemy of tobacco. He politely refers to "that great Tobacconist, the Prince of Smoake and Darkness, Don Pluto"; and in another place addresses tobacco as "thou beggarly Monarche of Indians, and setter up of rotten-lungd chimney-sweepers," and proceeds in a like strain of abuse.

From Chapter 8:
A famous crony of Parr's, the learned Porson, was another devotee of tobacco. In November 1789 Parr wrote to Dr. Burney: "The books may be consulted, and Porson shall do it, and he will do it. I know his price when he bargains with me; two bottles instead of one, six pipes instead of two, burgundy instead of claret, liberty to sit till five in the morning instead of sneaking into bed at one: these are his terms:" and these few lines, it may be added, give a graphic picture of Porson. According to Maltby, Porson once remarked that when smoking began to go out of fashion, learning began to go out of fashion also—which shows what nonsense a learned man could talk.
