From Chapter 1:
Who first smoked a pipe of tobacco in England? The honour is divided among several claimants. It has often been stated that Captain William Middleton or Myddelton (son of Richard Middleton, Governor of Denbigh Castle), a Captain Price and a Captain Koet were the first who smoked publicly in London, and that folk flocked from all parts to see them; and it is usually added that pipes were not then invented, so they smoked the twisted leaf, or cigars. This account first appeared in one of the volumes of Pennant's "Tour in Wales." But the late Professor Arber long ago pointed out that the remark as to the mode of smoking by cigars and not by pipes was simply Pennant's speculation. The authority for the rest of the story is a paper in the Sebright MSS., which, in an account of William Middleton, has the remark: "It is sayed, that he, with Captain Thomas Price of Plâsyollin and one Captain Koet, were the first who smoked, or (as they called it) drank tobacco publickly in London; and that the Londoners flocked from all parts to see them." No date is named, and no further particulars are available.

From Chapter 7:
Warton and another Oxford smoker of some distinction—the Rev. William Crowe, who was Public Orator from 1784 to 1829—are both said to have been, like Prior, rather fond of frequenting the company of persons of humble rank and little education, with whom they would drink their ale and smoke their pipes.

Mr. A.D. Godley, in his "Oxford in the Eighteenth Century," gives an excellent English version of the Latin original of one of the Christ Church "Carmina Quadragesmalia," which affords much the same picture of the daily life of an Oxford Fellow in the days when George I was king. This good man lives strictly by rule, and each returning day—

Ne'er swerves a hairbreadth from the same old way.
Always within the memory of men
He's risen at eight and gone to bed at ten:
The same old cat his College room partakes,
The same old scout his bed each morning makes:
On mutton roast he daily dines in state
(Whole flocks have perished to supply his plate),
Takes just one turn to catch the westering sun,
Then reads the paper, as he's always done;
Soon cracks in Common-room the same old jokes,
Drinking three glasses ere three pipes he smokes:—
And what he did while Charles our throne did fill
'Neath George's heir you'll find him doing still.
