From Chapter 2:
When Robert, Earl of Essex, and Henry, Earl of Southampton, were tried for high treason in Westminster Hall on February 19, 1600-1, the members of the House of Lords, who with the Judges formed the Court, if we may believe the French Ambassador of the time, behaved in a remarkable and unseemly manner. In a letter to Monsieur de Rohan, the Ambassador declared that while the Earls and the Counsel were pleading, their lordships guzzled and smoked; and that when they gave their votes condemning the two Earls, they were stupid with eating and "yvres de tabac"—drunk with smoking. This was probably quite untrue as a representation of what actually took place; but it would hardly have been written had smoking not been a common practice among noble lords.

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.'"
