From Chapter 4:
It seems likely that Richard Cromwell was a smoker. In 1689, long after he had retired into private life and had ample leisure for blowing clouds, he sent to a friend a "Boxe of tobacco," which was described as "A.J. Bod (den's) ... best Virginnea." In a letter to his daughter Elizabeth, dated 21 January 1705, there is a reference to this same dealer, whom he describes as "Adam Bodden, Bacconist in George Yard, Lumber [Lombard] Street." The allusion is worth noting as a very early instance of the colloquial trick of abbreviation familiar in later days in such forms as "baccy" and "bacca" and their compounds.

From Chapter 6:
After King William III was settled on the throne the sum of £600,000 was paid to the Dutch from the English exchequer for money advanced in connexion with his Majesty's expedition, and this amount was paid off by tobacco duties. Granger long ago remarked that most of the eminent divines and bishops of the day contributed very practically to the payment of this revolutionary debt by their large consumption of tobacco. He mentions Isaac Barrow, Dr. Barlow of Lincoln, who was as regular in smoking tobacco as at his meals, and had a high opinion of its virtues, Dr. Aldrich, "and other celebrated persons who flourished about this time, and gave much into that practice." One of the best known of these celebrated persons was Gilbert Burnet, Bishop of Salisbury from 1689, and historian of his own times. He had the reputation of being an inveterate smoker, and was caricatured with a long clay stuck through the brim of the shovel hat, on the breadth of which King William once made remark. The bishop replied that the hat was of a shape suited to his dignity, whereupon the King caustically said, "I hope that the hat won't turn your head."
