From Chapter 1:
"'It requires no effort of the fancy to picture these three men [Shakespeare, Bacon and Raleigh] as lounging in a window of Durham House, puffing the new Indian weed from silver bowls, discussing the highest themes in poetry and science, while gazing on the flower-beds and the river, the darting barges of dame and cavalier, and the distant pavilions of Paris garden and the Globe.'" This is a pure "effort of the fancy" so far as Bacon and Shakespeare are concerned. Shakespeare's absolute silence about tobacco forbids us to assume that he smoked; but of Raleigh the picture may be true enough. The house had, as Aubrey tells us, "a little turret that looked into and over the Thames, and had the prospect which is as pleasant perhaps as any in the world"; and it would be strange indeed if the owner of the noble house did not often smoke a contemplative pipe in the window of that pleasant turret.

From Chapter 8:
In the fashionable world the snuff-box was all-powerful. The Prince Regent was devoted to snuff, but disdained tobacco. He had a "cellar of snuff," which after his death was sold, said John Bull, August 15, 1830, "to a well-known purveyor, for £400." Lord Petersham, famous among dandies, made a wonderful collection of snuffs and snuff-boxes, and was curious in his choice of a box to carry. Gronow relates that once when a light Sèvres snuff-box which Lord Petersham was using, was admired, the noble owner replied, with a gentle lisp—"Yes, it is a nice summer box—but would certainly be inappropriate for winter wear!" The well-known purveyor who bought the Prince Regent's cellar of snuff, and who bought also Lord Petersham's stock, was the Fribourg of Fribourg and Treyer, whose well-known old-fashioned shop at the top of the Haymarket, with a bow-window on each side of the door, still gives an eighteenth-century flavour to that thoroughfare. All the dandies of the period were connoisseurs of snuff, and imitated the royal mirror of fashion in their devotion to the scented powder. Young Charles Stanhope wrote to his brother on November 5, 1812—"I have learnt to take snuff among other fashionable acquirements, a custom which, of course, you have learnt and will be able to keep me in countenance." But no dandies or young men of fashion smoked. Tobacco, save in the disguise of snuff, was tabooed.
