From Chapter 4:
We know also that the Roundhead soldiers smoked in circumstances that did them no credit. In the account of the trial of Charles I, written by Dr. George Bates, principal physician to his Majesty, and to Charles II also, we read that when the sentence of the Court presided over by Bradshaw, condemning the King "to death by severing his Head from his Body," had been read, the soldiers treated the fallen monarch with great indignity and barbarity. They spat on his clothes as he passed by, and even in his face; and they "blew the smoak of tobacco, a thing which they knew his Majesty hated, in his sacred mouth, throwing their broken Pipes in his way as he passed along."

From Chapter 6:
Even children seem to have smoked sometimes in the coffee-houses. Ralph Thoresby, the Leeds antiquary, tells a strange story. He declares that, one evening which he spent with his brother at Garraway's Coffee-house, February 20, 1702, he was surprised to see his brother's "sickly child of three years old fill its pipe of tobacco and smoke it as audfarandly as a man of three score; after that a second and a third pipe without the least concern, as it is said to have done above a year ago." A child of two years of age smoking three pipes in succession is a picture a little difficult to accept as true. As this is the only reference to tobacco in the whole of his "Diary," it is not likely that Thoresby was himself a smoker.
