From Chapter 3:
"A Tobacco-Seller," says Earle, "is the onely man that findes good in it which others brag of, but do not; for it is meate, drinke, and clothes to him. No man opens his ware with greater seriousnesse, or challenges your judgement more in the approbation. His shop is the Randevous of spitting, where men dialogue with their noses, and their communication is smoake. It is the place onely where Spaine is commended, and prefer'd before England itselfe. He should be well experienc'd in the world: for he ha's daily tryall of mens nostrils, and none is better acquainted with humors. Hee is the piecing commonly of some other trade which is bawde to his Tobacco, and that to his wife, which is the flame that follows this smoke."

From Chapter 8:
Notwithstanding the unfashionableness of tobacco, there were still some noteworthy smokers to be found among the clergy. Dr. Sumner, head master of Harrow, who died in 1771, was devoted to his pipe. The greatest of clerical "tobacconists" of late eighteenth century and early nineteenth century date was the once famous Dr. Parr. It was from him that Dr. Sumner learned to smoke. When he and Parr got together Sumner was in the habit of refilling his pipe again and again in such a way as to be unobserved, at the same time begging Parr not to depart till he had finished his pipe, in order that he might detain him, we are told, in the evening as long as possible.
