From Chapter 3:
The fumes of dried coltsfoot leaves were used as a remedy in cases of difficulty of breathing, both in ancient Roman times and in Tudor England. Lyte, in his translation, 1578, of Dodoens' "Historie of Plants," says of coltsfoot: "The parfume of the dryed leaves layde upon quicke coles, taken into the mouth through the pipe of a funnell, or tunnell, helpeth suche as are troubled with the shortnesse of winde, and fetche their breath thicke or often, and do [sic] breake without daunger the impostems of the breast." The leaves of coltsfoot and of other plants have often been used as a substitute for tobacco in modern days. A correspondent of Notes and Queries, in 1897, said that when he was a boy he knew an old Calvinist minister, who used to smoke a dried mixture of the leaves of horehound, yarrow and "foal's foot" intermingled with a small quantity of tobacco. He said it was a very good substitute for the genuine article. Similar mixtures, or the leaves of coltsfoot alone, have often been smoked in bygone days by folk who could not afford to smoke tobacco only.

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."
