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 8:
Parr is said on one occasion to have called for a pipe after taking a meal at a coaching-inn called the "Bush" at Bristol, when the waiter told him that smoking was not allowed at the Bush. Parr persisted, but the authorities at the inn were firm in their refusal to allow anything so vulgar as smoking on their premises, whereupon Parr is said to have exclaimed: "Why, man, I've smoked in the dining-room of every nobleman in England. The Duchess of Devonshire said I could smoke in every room in her house but her dressing-room, and here, in this dirty public-house of Bristol you forbid smoking! Amazing! Bring me my bill." The learned doctor exaggerated no doubt as regards the facilities given him for smoking; for it was his overbearing way not to ask for leave to smoke, but to smoke wherever he went, whether invited to do so or not; but the story shows the prejudice against smoking which was found in many places as a result of the attitude of the fashionable world towards tobacco.
