From Chapter 1:
Perhaps the most likely scene of Raleigh's first experiments in the art of smoking was Durham House, which stood where the Adelphi Terrace and the streets between it and the Strand now stand. This was in the occupation of Sir Walter for twenty years (1583-1603), and he was probably resident there when Hariot returned from Virginia to make his report and instruct his employer in the management of a pipe. Walter Thornbury, in his "Haunted London," referring to the story of the servant throwing the ale over his smoking master, says: "There is a doubtful old legend about Raleigh's first pipe, the scene of which may be not unfairly laid at Durham House, where Raleigh lived." The ale story is mythical, but it is highly probable that Sir Walter's first pipes were smoked in Durham House. Dr. Brushfield quotes Hepworth Dixon, in "Her Majesty's Tower," as drawing "an imaginary and yet probable picture of him and his companions at a window of this very house, overlooking the 'silent highway':

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.
