From Chapter 4:
From the various entries in the "Diary" relating to the purchase of tobacco, it seems clear that there was no shop in Exeter devoted specially or exclusively to the sale of the weed. Hayne bought his supplies from four of the leading goldsmiths of the city, who can be identified by the fact that he had dealings with them in their own special wares, also from two drapers, one grocer, and four other tradesmen (on a single occasion each) whose particular occupations are unknown.

From Chapter 11:
About the time that Lang's article was written, Sir F.C. Burnand's burlesque, "Bluebeard" was produced at the Gaiety Theatre. In those days a certain type of young man, since known by many names, including the present day "nut," was called a "masher"; and Burnand's burlesque included a duet with the refrain:

We are mashers, we are,
As we smoke our cigar
And crawl along, never too quick;
We are mashers, you bet,
With the light cigarette
And the quite irreproachable stick.

Nowadays the cigarette is in such universal use, that it would be impossible thus to associate it with any particular type of man, sane or inane.

All-virtuous Herbert! on whose every part
Truth might spend all her voice, fame all her art!—
was a smoker, as we know from a very curious passage in his well-known autobiography. He appears to have smoked not so much for pleasure as for supposed reasons of health. "It is well known," he wrote, "to those that wait in my chamber, that the shirts, waistcoats, and other garments I wear next my body, are sweet, beyond what either can easily be believed, or hath been observed in any else, which sweetness also was found to be in my breath above others, before I used to take tobacco, which towards my latter time I was forced to take against certain rheums and catarrhs that trouble me, which yet did not taint my breath for any long time." The autobiography was written about 1645, so as Lord Herbert did not smoke till towards the latter part of his life—he died in 1648—he clearly was not one of those who took to tobacco in the first enthusiasm for the new indulgence.

From Chapter 10:
The flight of fancy in the last sentence has hardly yet been fulfilled; but I saw, many years ago, a distinguished man of letters, the late Mr. Francis Turner Palgrave, of "Golden Treasury" fame, who was an inveterate smoker, sitting on one of the cane benches by the door of the Athenæum Club, smoking a short clay pipe.

Thackeray does not appear to have realized that tobacco was not invading England for the first, but for the second time, nor did he foresee that the ladies, to whom he addressed his impassioned defence of smoking, would not only submit to the conqueror but would themselves be found among his joyous devotees.
