The Description of a New World, Called the Blazing-World

To which they answered, That there was a certain Rock in the parts of that World, which contained the Golden Sands, which Rock was hallow within, and did produce a Gum that was a hundred years before it came to its full strength and perfection; this Gum, said they, if it be held in a warm hand, will dissolve into an Oyl, the effects whereof are following: It being given every day for some certain time, to an old decayed man, in the bigness of a little Pea, will first make him spit for a week, or more; after this, it will cause Vomits of Flegm; and after that it will bring forth by vomits, humors of several colours; first of a pale yellow, then of a deep yellow, then of a green, and lastly of a black colour; and each of these humours have a several taste, some are fresh, some salt, some sower, some bitter, and so forth; neither do all these Vomits make them sick, but they come out on a sudden, and unawares, without any pain or trouble to the patient: And after it hath done all these mentioned effects, and clear'd both the Stomack and several other parts of the body, then it works upon the Brain, and brings forth of the Nose such kinds of humors as it did out of the Mouth, and much after the same manner; then it will purge by stool, then by urine, then by sweat, and lastly by bleeding at the Nose, and the Emeroids; all which effects it will perform within the space of six weeks, or a little more; for it does not work very strongly, but gently, and by degrees: Lastly, when it has done all this, it will make the body break out into a thick Scab, and cause both Hair, Teeth, and Nails to come off; which scab being arrived to its full maturity, opens first along the back, and comes off all in a piece like armour, and all this is done within the space of four months.
