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."

From Chapter 11:
The earliest references for the word "cigarette" in the Oxford Dictionary are dated 1842 and 1843, but both refer to the smoking of cigarettes abroad—in France and Italy. The 1843 quotation is from a book by Mrs. Romer, in which she says—"The beggars in the streets have paper cigars (called cigarettes) in their mouths." The wording here would seem to show that cigarettes were not then familiar to English people.
