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:
If smoking had died out at Oxford its decline must have been rapid. When a certain young John James was an undergraduate of Queen's, 1778 to 1781, he and his correspondents spoke severely of the "miserable condition of Fellows who (under the liberal pretence of educating youth) spend half their lives in smoking tobacco and reading the newspapers." About 1800 the older or more old-fashioned of the Fellows at New College, "not liking the then newly introduced luxury of Turkey carpets," says Mr. G.V. Cox, in his "Recollections of Oxford," 1868, "often adjourned to smoke their pipe in a little room opposite to the Senior Common-room, now appropriated to other uses, but then kept as a smoking-room." A Mr. Rhodes, a one-time Fellow of Worcester College, who was elected Esquire Bedel in Medicine and Arts in 1792, had a very peculiar way of enjoying his tobacco. Mr. Cox says: "On one occasion, when I had to call upon him, I found him drinking rum and water, and enjoying (what he called his luxury) the fumes of tobacco, not through a pipe or in the shape of a cigar, but burnt in a dish!"
