Just like unto a Nest of Boxes round, Degrees of sizes within each Boxe are found. So in this World, may many Worlds more be, Thinner, and lesse, and lesse still by degree; Although they are not subject to our Sense, A World may be no bigger than two-pence. Nature is curious, and such worke may make, That our dull Sense can never finde, but scape. For Creatures, small as Atomes, may be there, If every Atome a Creatures Figure beare. If foure Atomes a World can make, then see, What severall Worlds might in an Eare-ring bee. For Millions of these Atomes may bee in The Head of one small, little, single Pin. And if thus small, then Ladies well may weare A World of Worlds, as Pendents in each Eare.
