From Chapter 1:
In November 1911 a curiously shaped pipe was put up for sale in Mr. J.C. Stevens's Auction Room, Covent Garden, which was described as that which Raleigh smoked "on the scaffold." The pipe in question was said to have been given by the doomed man to Bishop Andrewes, in whose family it remained for many years, and it was stated to have been in the family of the owner, who sent it for sale, for some 200 years. The pipe was of wood constructed in four pieces of strange shape, rudely carved with dogs' heads and faces of Red Indians. According to legend it had been presented to Raleigh by the Indians. The auctioneer, Mr. Stevens, remarked that unfortunately a parchment document about the pipe was lost some years ago, and declared, "If we could only produce the parchment the pipe would fetch £500." In the end, however, it was knocked down at seventy-five guineas.

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.
