From Chapter 1:
The only mention made of tobacco by Raleigh himself occurs in a testamentary note made a little while before his execution in 1618. Referring to the tobacco remaining on his ship after his last voyage, he wrote: "Sir Lewis Stukely sold all the tobacco at Plimouth of which, for the most part of it, I gave him a fift part of it, as also a role for my Lord Admirall and a role for himself ... I desire that hee may give his account for the tobacco." As showing how closely Sir Walter's name was associated with it long after his death, Dr. Brushfield quotes the following entry from the diary of the great Earl of Cork: "Sept. 1, 1641. Sent by Travers to my infirme cozen Roger Vaghan, a pott of Sir Walter Raleighes tobackoe."

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.
