 insignificant size : but we cease to think them insignificant, 

 when we reflect that it is by means of the smallest objects, 

 that Nature every where produces her most remarkable and 

 astonishing phenomena. Whatever she may seem to lose 

 in point of volume in the production of living bodies, is amply 

 made up by the number of the individuals, which she multi- 

 plies with admirable promptitude to infinity. The remains 

 of such minute animals have added much more to the mass 

 of materials which compose the exterior crust of the globe, 

 than the bones of Elephants, Hippopotami, and Whales.
