From Chapter 4:
It is somewhat singular that the Puritans, who denounced most amusements and pleasures, and who frowned upon most of the occupations or diversions that make for gaiety and the enjoyment of life, did not, as Puritans, denounce the use of tobacco. One or two of their writers abused it roundly; but these were not representative of Puritan feeling on the subject. The explanation doubtless is that the practice of smoking was so very general and so much a matter of course among men of all ranks and of all opinions, that the mouths of Puritans were closed, so to speak, by their own pipes. A precisian, however, could take his tobacco with a difference. The seventeenth-century diarist, Abraham de la Pryme, says that he had heard of a Presbyterian minister who was so precise that "he would not as much as take a pipe of tobacco before that he had first sayed grace over it." George Wither, one of the most noteworthy of the poets who took the side of the Parliament, was confined in Newgate after the Restoration, and found comfort in his pipe.

From Chapter 8:
Dr. Farmer was elected Master of Emmanuel in 1775. Years before he had held the curacy of Swavesey, about nine miles out of Cambridge, where he regularly performed the duty. After morning service it was his custom to repair to the local public-house where he enjoyed a mutton-chop and potatoes. Immediately after the removal of the cloth, "Mr. Dobson (his churchwarden) and one or two of the principal farmers, made their appearance, to whom he invariably said, 'I am going to read prayers, but shall be back by the time you have made the punch.' Occasionally another farmer accompanied him from church, when pipes and tobacco"—with the punch—"were in requisition until 6 o'clock." The Sabbath afternoon thus satisfactorily concluded, Farmer returned to college in Cambridge and took a nap, till at nine he went to the parlour of the college where the Fellows usually assembled, and pipes and tobacco concluded a well-spent day.
