From Chapter 3:
Another tract which may be classed with Venner's "Treatise" was the "Nepenthes or the Vertues of tobacco," by Dr. William Barclay, which was published at Edinburgh in 1614. This is sometimes referred to and quoted, as by Fairholt, as if it were a whole-hearted defence of tobacco-taking. But Barclay enlarges mainly on the medicinal virtues of the herb. "If Tabacco," he says, "were used physically and with discretion there were no medicament in the worlde comparable to it"; and again: "In Tabacco there is nothing which is not medicine, the root, the stalke, the leaves, the seeds, the smoake, the ashes." The doctor gives sundry directions for administering tobacco—"to be used in infusion, in decoction, in substance, in smoke, in salt." But Barclay clearly does not sympathize with its indiscriminate use for pleasure. "As concerning the smoke," he says, "it may be taken more frequently, and for the said effects, but always fasting, and with emptie stomack, not as the English abusers do, which make a smoke-boxe of their skull, more fit to be carried under his arme that selleth at Paris dunoir a noircir to blacke mens shooes then to carie the braine of him that can not walke, can not ryde except the Tabacco Pype be in his mouth." He goes on to say that he was once in company with an English merchant in Normandy—"betweene Rowen and New-haven"—who was a merry fellow, but was constantly wanting a coal to kindle his tobacco. "The Frenchman wondered and I laughed at his intemperancie."

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!"
