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 5:
Clouds were blown under archiepiscopal roofs. At Lambeth Palace one Sunday in February 1672 John Eachard, the author of the famous book or tract on "The Contempt of the Clergy," 1670, which Macaulay turned to such account, dined with Archbishop Sheldon. He sat at the lower end of the table between the archbishop's two chaplains; and when dinner was finished, Sheldon, we are told, retired to his withdrawing-room, while Eachard went with the chaplains and another convive to their lodgings "to drink and smoak."
