From The Secret Commonwealth of Elves, Fauns and Fairies by Robert Kirk (1644-1692). (Find more here about Kirk and this work of his.) The first paragraph is my rewrite into modern English, and the next is the original spelling:
Their bodies of congealled air are some times caried aloft. Other times they grovel in different shapes, and enter into any cranny or cleft of the earth where air enters, to their ordinary dwellings (the earth being full of cavities and cells)—and there being no place nor creature but is supposed to have other animals (greater or lesser) living in or upon it as inhabitants; and no such thing as a pure wilderness in the whole universe.
