From Chapter 4:
In this "Diary," covering the years 1631-43, there are some forty entries concerning the purchase of what is always, save in one case, called "tobacka." These entries give valuable information as to the prices of the two chief kinds of tobacco. One was imported from Spanish America, which up to 1639 Hayne calls "Varinaes," and after that date "Spanish"; the other was imported from English colonies—chiefly from Virginia. The "Varinaes" kind, Dr. Brushfield suggests, was obtained from Varina, near the foot of the range of mountains forming the west boundary of Venezuela, and watered by a branch of the Orinoco River. Hayne also notes the purchase of "Tertudoes" tobacco, but what that may have been I cannot say. From the various entries relating respectively to Varinaes or Spanish tobacco, and to Virginia tobacco, it is clear that the former ranged in price from 8s. to 13s. per lb., while the latter was from 1s. 6d. to 4s. per lb. There is one entry of "perfumed Tobacka," 10 oz. of which were bought at the very high price of 15s. 6d.

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.
