From Chapter 3:
Taking the whiff, it has been suggested, may have been either a swallowing of the smoke, or a retaining it in the throat for a given space of time; but what may be meant by the "Cuban ebolition" or the "euripus" is perhaps best left to the imagination. "Ebolition" is simply a variant of "ebullition," and "ebullition," as applied with burlesque intent to rapid smoking—the vapour bubbling rapidly from the pipe-bowl—is intelligible enough, but why Cuban? "Euripus" was the name, in ancient geography, of the channel between Eubœa (Negropont) and the mainland—a passage which was celebrated for the violence and uncertainty of its currents—and hence the name was occasionally applied by our older writers to any strait or sea-channel having like characteristics. The use of the word in connexion with tobacco may, like that of "ebolition," have some reference to furious smoking, but the meaning is not clear.

From Chapter 7:
It has sometimes been said that Swift smoked; but this is a mistake. He had a fancy for taking tobacco in a slightly different way from the fashionable mode of taking snuff. He told Stella that he had left off snuff altogether, and then in the very next sentence remarked that he had "a noble roll of tobacco for grating, very good." And in a later letter to Stella, May 24, 1711, he asked if she still snuffed, and went on to say, in sentences that seem to contradict one another: "I have left it off, and when anybody offers me their box, I take about a tenth part of what I used to do, then just smell to it, and privately fling the rest away. I keep to my tobacco still, as you say; but even much less of that than formerly, only mornings and evenings, and very seldom in the day." One might infer from this that he smoked, but this Swift never did. His practice was to snuff up cut and dried tobacco, which was sometimes just coloured with Spanish snuff. This he did all his life, but as the mixture he took was not technically snuff, he never owned that he took snuff.

Another cleric of the period, well known to fame, who took snuff but also loved his pipe, was Samuel Wesley, rector of Epworth, Lincolnshire, from 1697 to 1735. He not only smoked his pipe, but sang its praises:

In these raw mornings, when I'm freezing ripe,
What can compare with a tobacco-pipe?
Primed, cocked and toucht, 'twould better heat a man
Than ten Bath Faggots or Scotch warming-pan.

Samuel's greater son, John Wesley, did not share the parental love of a pipe. He spoke of the use of tobacco as "an uncleanly and unwholesome self-indulgence," and described snuffing as "a silly, nasty, dirty custom."
