From Chapter 9:
By 1830 smoking had so far "come in" again that a considerable proportion of the members of the House of Commons were smokers. Macaulay has drawn for us the not very attractive picture of the smoking-room of the old House of Commons—before the fire of 1834—in a letter to his sister dated in the summer of 1831. "I have left Sir Francis Burdett on his legs," he wrote, "and repaired to the smoking-room; a large, wainscoted, uncarpeted place, with tables covered with green baize and writing materials. On a full night it is generally thronged towards twelve o'clock with smokers. It is then a perfect cloud of fume. There have I seen (tell it not to the West Indians), Buxton blowing fire out of his mouth. My father will not believe it. At present, however, all the doors and windows are open, and the room is pure enough from tobacco to suit my father himself." In July 1832 he again dated a letter to his sisters from the House of Commons smoking-room. "I am writing here," he says, "at eleven at night, in this filthiest of all filthy atmospheres ... with the smell of tobacco in my nostrils.... Reject not my letter, though it is redolent of cigars and genuine pigtail; for this is the room—

The room,—but I think I'll describe it in rhyme,
That smells of tobacco and chloride of lime.
The smell of tobacco was always the same:
But the chloride was bought since the cholera came."

From Chapter 14:
Another eighteenth-century instance of smoking in church, taken from historical fact and not from fiction, is associated with the church of Hayes, in Middlesex. The parish registers of that village bear witness to repeated disputes between the parson and bell-ringers and the parishioners generally in 1748-1754. In 1752 it was noted that a sermon had been preached after a funeral "to a noisy congregation." On another occasion, says the register, "the ringers and other inhabitants disturbed the service from the beginning of prayers to the end of the sermon, by ringing the bells, and going into the gallery to spit below"; while at yet another time "a fellow came into church with a pot of beer and a pipe," and remained "smoking in his own pew until the end of the sermon." Going to church at Hayes in those days must have been quite an exciting experience. No one knew what might happen next.
