From Chapter 2:
Ben Jonson has given us an amusing picture of the behaviour of gallants on the Elizabethan stage, in his "Cynthia's Revels." In this scene a child thus mimics the obtrusive beau: "Now, sir, suppose I am one of your genteel auditors, that am come in (having paid my money at the door, with much ado), and here I take my place, and sit downe. I have my three sorts of tobacco in my pocket, my light by me, and thus I begin. 'By this light, I wonder that any man is so mad, to come to see these rascally tits play here—they do act like so many wrens—not the fifth part of a good face amongst them all—and then their musick is abominable—able to stretch a man's ears worse than ten—pillories, and their ditties—most lamentable things, like the pitiful fellows that make them—poets. By this vapour—an't were not for tobacco—I think—the very smell of them would poison me, I should not dare to come in at their gates. A man were better visit fifteen jails—or a dozen or two hospitals—than once adventure to come near them.'" And the young rascal, who at each pause marked by a dash had puffed his pipe, no doubt blowing an extra large "cloud" when he swore "by this vapour," turns to his companions and says: "How is't? Well?" and they pronounce his mimicry "Excellent!"

From Chapter 5:
At the time of the Great Plague all kinds of nostrums were sold and recommended as preservatives or as cures. Most of these perished with the occasion that called them forth; but the names of some have been preserved in a rare quarto tract which was published in the Plague year, 1665, entitled "A Brief Treatise of the Nature, Causes, Signes, Preservation from and Cure of the Pestilence," "collected by W. Kemp, Mr. of Arts." In the list of devices for purifying infected air it is stated that "The American Silver-weed, or Tobacco, is very excellent for this purpose, and an excellent defence against bad air, being smoked in a pipe, either by itself, or with Nutmegs shred, and Rew Seeds mixed with it, especially if it be nosed"—which, I suppose, means if the smoke be exhaled through the nose—"for it cleanseth the air, and choaketh, suppresseth and disperseth any venomous vapour." Mr. Kemp warms to his subject and proceeds with a whole-hearted panegyric that must be quoted in full: "It hath singular and contrary effects, it is good to warm one being cold, and will cool one being hot. All ages, all Sexes, all Constitutions, Young and Old, Men and Women, the Sanguine, the Cholerick, the Melancholy, the phlegmatick, take it without any manifest inconvenience, it quencheth thirst, and yet will make one more able, and fit to drink; it abates hunger, and yet will get one a good stomach; it is agreeable with mirth or sadness, with feasting and with fasting; it will make one rest that wants sleep, and will keep one waking that is drowsie; it hath an offensive smell to some, and is more desirable than any perfume to others; that it is a most excellent preservative, both experience and reason do teach; it corrects the air by Fumigation, and it avoids corrupt humours by Salivation; for when one takes it either by Chewing it in the leaf, or Smoaking it in the pipe, the humors are drawn and brought from all parts of the body, to the stomach, and from thence rising up to the mouth of the Tobacconist, as to the helme of a Sublimatory, are voided and spitten out."
