But above all I would beg my reading merry Friends of the thoughtless kind not to be so much surpriz'd at the Apparitions of their own Brain; not to start and be frighted when they first make Devils by Day-light, and then see them in the dark; and as they may be assur'd they will hardly ever see any thing worse than themselves, so let them resolve not to be scar'd at Shadows, or amus'd with Vapours; mistaking the Devil for an Ass, and tell us of the Saucer Eyes of a Pink-eyed Bear; not fancy they see a Hearse with headless Horses, and take the Night Cart for a fiery Chariot, which one would think they might distinguish by their Noses, unless they will own that their Fear gave them a worse Smell than that of the Devil.
