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 underground have not such an optic 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 advantageous to them. The Empress seemed 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 laughed? We most humbly beg your Majesty’s pardon, replied they; for we could not choose but laugh, when we heard of a colourless body. Why, said the Empress, colour is only an accident, which is an immaterial thing, and has no being of itself, but in another body.
