From Chapter 1:
In this "Report" Hariot says of the tobacco plant: "There is an herbe which is sowed a part by itselfe and is called by the inhabitants Vppówoc: In the West Indies it hath divers names, according to the severall places and countries where it groweth and is used: The Spaniardes generally call it Tobacco. The leaves thereof being dried and brought into powder: they use to take the fume or smoke thereof by sucking it through pipes made of claie into their stomacke and heade: from whence it purgeth superfluous fleame and other grosse humors, openeth all the pores and passages of the body: by which meanes the use thereof, not only preserveth the body from obstructions: but if also any be, so that they have not beane of too long continuance, in short time breaketh them: wherby their bodies are notably preserved in health, and know not many greevous diseases wherewithall wee in England are oftentimes afflicted."

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."
