From Chapter 1:
Wherever Raleigh is known to have lived or lodged we are sure to find the tradition flourishing that there he smoked his first pipe. The assertion has been made of his birthplace, Hayes Barton, although it is very doubtful if he ever visited the place after his parents left it, some years before their son had become acquainted with tobacco; and also with more plausibility of his home at Youghal, in the south of Ireland. Froude, in one of his "Short Studies," quotes a legend to the effect that Raleigh smoked on a rock below the Manor House of Greenaway, on the River Dart, which was the home of the first husband of Katherine Champernowne, afterwards Raleigh's wife; and Devonshire guide-books have adopted the story.

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.
