From Chapter 10:
Thackeray, as the satirist of the foolish social prejudices against smoking, was naturally an inveterate smoker himself. He died in 1863, and so hardly saw the beginning of a change in the attitude of society towards the pestilent weed; but he was one of the many men of letters and artists, who, despising the conventions of society, were largely instrumental in breaking down stupid restrictions, and in overcoming senseless prejudices, and were thus heralds of freedom. Charles Keene's attitude was that of many artists. He smoked a little Jacobean clay pipe in his "sky-parlour" overlooking the Strand, and did not care in the least what the world might think or not think about that or any other subject.

From Chapter 15:The figure was usually made with a snuff mull in his hand—the highlander being always credited with a great love and a great capacity for snuff-taking. But one curious example was furnished, not only with a mull but with a bat-like implement of unknown use. Mr. Arthur Denman, F.S.A., writing in Notes and Queries, April 17, 1909, said: "I have a very neat little, genuine specimen of the old tobacconist's sign of a 42nd Highlander with his 'mull.' It is 3 ft. 6 in. high, and it differs from those usually met with in that under the left arm is an implement almost exactly like a cricket-bat. This bat has a gilt knob to the handle, and on the shoulder of it are three chevrons in gold, without doubt a sergeant's stripes. On the exposed side of the bat is what would appear to represent a loose strip of wood. This strip is nearly one-third of the width of the instrument, and extends up the middle about two-fifths of the length of the body of it. I can only guess that the bat was, at some time, primarily, an emblem of a sergeant's office, and, secondarily, used for the infliction of chastisement on clumsy or disorderly recruits; and perhaps it was equivalent to the Prügel of German armies, with which sergeants drove lagging warriors into the fray. But is there any record of such an accoutrement as being that of a sergeant in the British army? and what was the purpose of the loose strip, unless it was to cause the blow administered to resound as much as to hurt, as does the wand of Harlequin in a booth."
