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 attractions and the atmosphere of provincial coffee-houses were much the same as those of the London resorts. A German gentleman who visited Cambridge in July and August 1710 remarked that in the Greeks' coffee-house in that town, in the morning and after 3 o'clock in the afternoon, you could meet the chief professors and doctors, who read the papers over a cup of coffee and a pipe of tobacco. One of the learned doctors took the German visitor to the weekly meeting of a Music Club in one of the colleges. Here were assembled bachelors, masters and doctors of music of the University—no professionals were employed—who performed vocal and instrumental music to their mutual gratification, though, apparently, not to the satisfaction of the visitor, who records his opinion that the music was "very poor." "It lasted," he says, "till 11 P.M., there was besides smoking and drinking of wine, though we did not do much of either. At 11 the reckoning was called for, and each person paid 2s."
