From Chapter 4:
There is a curious entry in Thomas Burton's diary of the proceedings of Cromwell's Parliament, which suggests that there may then have been the luxury of a members' smoking-room. Burton was a member of the Parliaments of Oliver and Richard Cromwell from 1656 to 1659, and made a practice—for which historical students have been and are much his debtors—of taking notes of the debates as he sat in the House. Members sometimes objected to and protested against this note-taking, but Burton quietly went on using his pencil, and though his summaries of speeches are often difficult to follow, argument and sense suffering by compression, he has preserved much very valuable matter. Referring to a debate on January 7, 1656-57, on an attempt to go behind the previously passed Act of Oblivion, the diarist records that "Sir John Reynolds had numbered the House, and said at rising there were 220 at the least, besides tobacconists." This can only mean that there were at least 220 members actually present in the House when it rose, not counting the "tobacconists" or smokers, who were enjoying their pipes, not in the Chamber itself, but in some conveniently adjoining place, which may have been a room for the purpose, or may simply have been the lobby referred to above in the extract from "Mercurius Pragmaticus."

From Chapter 7:
It seems to have been taken for granted that country parsons smoked. smoking was universal among their male parishioners from the squire to the labourer (when he could afford it), so that it was only natural that the parson, with little to do, and in those days not too much inclination to do it, should be as fond of his pipe as the rest of the world around him. In a World of 1756 there is an account of a country gentleman entertaining one evening the vicar of the parish, and the host as a matter of course proceeds to order a bottle of wine with pipes and tobacco to be placed on the table. The vicar forthwith "filled his pipe, and drank very cordially to my friend," his host. One cannot doubt that Laurence Sterne, that most remarkable of country parsons, smoked. His "My Uncle Toby" is among the immortals, and Toby without his pipe is unimaginable.
