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 8:
Cowper's aversion from tobacco could not have been very strong, for he encouraged his friend to smoke in the famous Summer House at Olney, which was the poet's outdoor study. Bull smoked Orinoco tobacco, which he carried in one of the tobacco-boxes, which in those days were much more commonly used than pouches, and this box on one occasion he accidentally left behind him at Olney. Cowper returned it to him with the well-known rhymed epistle dated June 22, 1782, and beginning:

If reading verse be your delight,
'Tis mine as much, or more, to write;
But what we would, so weak is man,
Lies oft remote from what we can.
