From Chapter 2:
When Robert, Earl of Essex, and Henry, Earl of Southampton, were tried for high treason in Westminster Hall on February 19, 1600-1, the members of the House of Lords, who with the Judges formed the Court, if we may believe the French Ambassador of the time, behaved in a remarkable and unseemly manner. In a letter to Monsieur de Rohan, the Ambassador declared that while the Earls and the Counsel were pleading, their lordships guzzled and smoked; and that when they gave their votes condemning the two Earls, they were stupid with eating and "yvres de tabac"—drunk with smoking. This was probably quite untrue as a representation of what actually took place; but it would hardly have been written had smoking not been a common practice among noble lords.

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.
