From Chapter 1:
All the evidence agrees that whoever taught Raleigh, it was Raleigh's example that brought smoking into notice and common use. Long before his death in 1618 it had become fashionable, as we shall see, in all ranks of society. He is said to have smoked a pipe on the morning of his execution, before he went to the scaffold, a tradition which is quite credible.

From Chapter 8:
Notwithstanding the unfashionableness of tobacco, there were still some noteworthy smokers to be found among the clergy. Dr. Sumner, head master of Harrow, who died in 1771, was devoted to his pipe. The greatest of clerical "tobacconists" of late eighteenth century and early nineteenth century date was the once famous Dr. Parr. It was from him that Dr. Sumner learned to smoke. When he and Parr got together Sumner was in the habit of refilling his pipe again and again in such a way as to be unobserved, at the same time begging Parr not to depart till he had finished his pipe, in order that he might detain him, we are told, in the evening as long as possible.

From Chapter 15:
Before the end of the seventeenth century, however, the signs were ceasing to have any necessary association with the trade carried on under them, and tobacconists are found with shop-signs which had no reference in any way to tobacco. For instance, to take a few examples from the late Mr. Hilton Price's lists of "Signs of Old London" from Cheapside and adjacent streets, in 1695 John Arundell, tobacconist, was at the "White Horse," Wood Street; in the same year J. Mumford, tobacconist, was at the "Faulcon," Laurence Lane; in 1699 Mr. Brutton, tobacconist, was to be found at the "Three Crowns," under the Royal Exchange; in 1702 Richard Bronas, tobacconist, was at the "Horse Shoe," Bread Street; and in 1766 Mr. Hoppie, of the "Oil Jar: Old Change, Watling Street End," advertised that he "sold a newly invented phosphorus powder for lighting pipes quickly in about half a minute. Ask for a Bottle of Thunder Powder."

Again, in Fleet Street, Mr. Townsend, tobacconist, traded in 1672 at the "Three Golden Balls," near St. Dunstan's Church; while at the end of Fetter Lane, a few years later, John Newland, tobacconist, was to be found at the "King's Head."

From Chapter 6:
Other well-known men of the late seventeenth century were "tobacconists" in the old sense of the word. Sir Isaac Newton is said to have smoked immoderately; and a familiar anecdote represents him as using for the purposes of a tobacco-stopper, in a fit of absent-mindedness, the little finger of a lady sitting beside him, whom he admired, but the truth of this legend is open to doubt. Thomas Hobbes, who lived to be ninety (1588-1679), was accustomed to dine at 11 o'clock, after which he smoked a pipe and then lay down and took a nap of about half an hour. No doubt he would have attributed the length of his days to the regularity of his habits. Izaak Walton, who also lived to be ninety, as the lover of the placid and contemplative life deserved to do, loved his pipe, though he seldom mentions smoking in the "Compleat Angler." Sir Samuel Garth, poet and physician, once known to fame as the author of "The Dispensary," was another pipe-lover, as is shown by his verses quoted at the head of this chapter. Dudley, the fourth Lord North, began to smoke in 1657, and, says Dr. Jessopp, "the habit grew upon him, the frequent entries for pipes and tobacco showing that he became more and more addicted to this indulgence. Probably it afforded him some solace in the dreadful malady from which he suffered so long."
