From Chapter 2:
Hentzner, the German traveller, who visited London in 1598, speaks of smoking being customary among the audience at plays, who were also supplied with "fruits, such as apples, pears and nuts, according to the season, carried about to be sold, as well as ale and wine." He was struck with the universal prevalence of the tobacco-habit. Not only at plays, but "everywhere else," he says, the "English are constantly smoking tobacco," and then he proceeds to describe how they did it: "They have pipes on purpose made of clay, into the further end of which they put the herb, so dry that it may be rubbed into powder; and putting fire to it, they draw the smoak into their mouths, which they puff out again through their nostrils, like funnels, along with it plenty of phlegm and defluxions from the head." This suggests that the unpleasant and quite unnecessary habit of spitting was common with these early smokers, a suggestion which is amply supported by other contemporary evidence.

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."
