From Chapter 4:
But to turn from this worthy Exeter citizen to more famous names: I do not know of any good evidence as to whether or not Cromwell smoked, although he is said to have taken an occasional pipe while considering the offer of the crown, but John Milton certainly did. The account of how the blind poet passed his days, after his retirement from public office, was first told by his contemporary Richardson, and has since been repeated by all his biographers. His placid day ended early. The poet took his frugal supper at eight o'clock, and at nine, having smoked a pipe and drunk a glass of water, he went to bed. Apparently this modest allowance of a daily evening pipe was the extent of Milton's indulgence in tobacco. He knew nothing of what most smokers regard as the best pipe of the day—the after-breakfast pipe.

From Chapter 5:
At the time of the Restoration tobacco-boxes which were considered suitable to the occasion were made in large numbers. The outside of the lid bore a portrait of the Royal Martyr; within the lid was a picture of the restored king, His Majesty King Charles II; while on the inside of the bottom of the box was a representation of Oliver Cromwell leaning against a post, a gallows-tree over his head, and about his neck a halter tied to the tree, while beside him was pictured the devil, wide-mouthed. Another form of memorial tobacco-box is described in an advertisement in the London Gazette of September 15, 1687. This was a silver box which had either been "taken out of the Bull's Head Tavern, Cheapside, or left in a Hackney Coach." It was "ingraved on the Lid with a Coat of Arms, etc., and a Medal of Charles the First fastened to the inside of the Lid, and engraved on the inside 'to Jacob Smith it doth belong, at the Black Lyon in High Holborn, date August 1671.'"
