For years, scientists with high power magnification at their fingertips have identified and labeled tens of thousands of microscopic creatures; the catalogs of microbiology are flush with Actinophrys, Noctiluca scintillans, Paramecium, and all manner of tiny creatures. ‘Since animalcules were visible only under a microscope, most of the city's residents had neither seen nor heard of them.’ ‘Leeuwenhoek tried ingenious ways to estimate the size of his animalcules.’ ‘The lowest plant, or animalcule, feeds, grows, and reproduces its kind.’ Through the techniques introduced by these first luminaries, our knowledge of what Leeuwenhoek called animalcules has deepened considerably.
