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 8:
Angelo gives some lively pictures of scenes of this kind in the London of about 1780. The Turk's Head, in Gerrard Street, was the meeting-place for "a knot of worthies, principally 'Sons of St. Luke,' or the children of Thespis, and mostly votaries of Bacchus," as the old fencing-master, who loved a little "fine writing," describes them; and here they sat, he says, "taking their punch and smoking, the prevailing custom of the time." About the same time (circa 1790) an evening resort for purposes mostly vicious was the famous Dog and Duck, in St. George's Fields. "The long room," says Angelo, "if I may depend on my memory, was on the ground floor, and all the benches were filled with motley groups, eating, drinking, and smoking." Angelo also mentions the "Picnic Society," a celebrated resort of fashion at the beginning of the nineteenth century, where the odour of tobacco never penetrated. It afforded, he says in his fine way, "a sort of antipodeal contrast to these smoking tavern clubs of the old city of Trinobantes." The same writer speaks of a certain Monsieur Liviez whom he met in Paris in 1772, who had been one of the first dancers at the Italian Opera House, and maître de ballet at Drury Lane Theatre. This gentleman was addicted to self-indulgence, loved good eating, and good and ample drinking, and moreover kept "late hours, Ã l'Anglaise, smoked his pipe, and drank oceans of punch."
