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

Then the Empress asked them, Whether by their Sensitive perceptions they could observe the interior corporeal, figurative Motions both of Vegetables and Minerals? They answer'd, That their Senses could perceive them after they were produced, but not before; Nevertheless, said they, although the interior, figurative motions of Natural Creatures are not subject to the exterior, animal, sensitive perceptions, yet by their Rational perception they may judg of them, and of their productions if they be regular: Whereupon the Empress commanded the Bear-men to lend them some of their best Microscopes. At which the Bear- men smilingly answered her Majesty, that their Glasses would do them but little service in the bowels of the Earth, because there was no light; for, said they, our Glasses do onely represent exterior objects, according to the various reflections and positions of light; and wheresoever light is wanting, the glasses wil do no good. To which the Worm-men replied, that although they could not say much of refractions, reflections, inflections, and the like; yet were they not blind, even in the bowels of the Earth: for they could see the several sorts of Minerals, as also minute Animals, that lived there; which minute Animal Creatures were not blind neither, but had some kind of sensitive perception that was as serviceable to them, as sight, taste, smell, touch, hearing, &c. was to other Animal Creatures: By which it is evident, That Nature has been as bountiful to those Creatures that live underground, or in the bowels of the Earth, as to those that live upon the surface of the Earth, or in the Air, or in Water. But howsoever, proceeded the Worm-men, although there is light in the bowels of the Earth, yet your Microscopes will do but little good there, by reason those Creatures that live under ground have not such an optick sense as those that live on the surface of the Earth: wherefore, unless you had such Glasses as are proper for their perception, your Microscopes will not be any ways advantagious to them. The Empress seem'd well pleased with this answer of the Worm-men; and asked them further, Whether Minerals and all other Creatures within the Earth were colourless? At which question they could not forbear laughing; and when the Empress asked the reason why they laught?
