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:
The London clergy seem to have smoked at one time as a matter of course at their gatherings at Sion College, their headquarters. An entry in the records under date February 14, 1682, relating to a Court Meeting, runs: "Paid Maddocks [the Messenger] for Attendinge and Pipes 6d." How long pipes continued to be concomitants of the meetings of the College's General Court I cannot say; but smoking and the annual dinners were long associated. At the anniversary feast in 1743 there were two tables to provide for, the total number of guests being about thirty, and two "corses" to each. The cost of the food, as Canon Pearce tells us in his excellent and entertaining book on the College and its Library, was £19 15s., or rather more than 13s. a head. The bill for wines and tobacco amounted to five guineas, or about 3s. 6d. a head, and for this modest sum the thirty convives enjoyed eleven gallons of "Red Oporto," one of "White Lisbon," and three of "Mountain," to the accompaniment of two pounds of tobacco (at 3s. 4d. the pound) smoked in "half a groce of pipes" (at 1s.).
