From Chapter 4:
One inference at least may be fairly drawn, I think, from this document, and that is that smoking was very popular north as well as south of the Tweed.

Tobacco was certainly cheap in Scotland. The following entries are from a MS. account of household expenses kept by the minister of the parish of Eastwood, near Glasgow, the Rev. William Hamilton. They cover two months only and show that the minister was a furious smoker. The prices given are in Scots currency, the pound Scots being worth about twenty pence sterling:

It may perhaps be interesting to compare with these prices, from which, apparently, it may be inferred that near Glasgow tobacco could be bought for some 5d. a pound, which seems incredibly cheap, the occasional expenditure upon tobacco of a worthy citizen of Exeter some few years earlier. Extracts from the "Financial Diary" of this good man, whose name was John Hayne, and who was an extensive dealer in serges and woollen goods generally, as well as in a smaller degree of cotton goods also, were printed some years ago, with copious annotations, by the late Dr. Brushfield.

From Chapter 5:
Clouds were blown under archiepiscopal roofs. At Lambeth Palace one Sunday in February 1672 John Eachard, the author of the famous book or tract on "The Contempt of the Clergy," 1670, which Macaulay turned to such account, dined with Archbishop Sheldon. He sat at the lower end of the table between the archbishop's two chaplains; and when dinner was finished, Sheldon, we are told, retired to his withdrawing-room, while Eachard went with the chaplains and another convive to their lodgings "to drink and smoak."
