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 6:
The more fashionable folk of the Restoration Era and later began to leave off if not to disdain the smoking-habit. Up to about 1700 smoking had been permitted in the public rooms at Bath, but when Nash then took charge, tobacco was banished. Public or at least fashionable taste had begun to change, and Nash correctly interpreted and led it. Sorbière, who has been quoted in the previous chapter, remarked in 1663 that "People of Quality" did not use tobacco so much as others; and towards the end of the century and in Queen Anne's time the tendency was for tobacco to go out of fashion. This did not much affect its general use; but the tendency—with exceptions, no doubt—was to restrict the use of tobacco to the clergy, to country squires, to merchants and tradesmen and to the humbler ranks of society—to limit it, in short, to the middle and lower classes of the social commonwealth as then organized. In the extraordinary record of inanity which Addison printed as the diary of a citizen in the Spectator of March 4, 1712, the devotion of the worthy retired tradesman to tobacco is emphasized. This is the kind of thing: "Monday ... Hours 10, 11 and 12 Smoaked three Pipes of Virginia ... one o'clock in the afternoon, chid Ralph for mislaying my Tobacco-Box.... Wednesday ... From One to Two Smoaked a Pipe and a half.... Friday ... From Four to Six. Went to the Coffee-house. Met Mr. Nisby there. Smoaked several Pipes."
