I observed certain animalcules, within whole bodies I saw so quick a motion as to exceed belief.
I saw in the body of one of these animalcules a bright and round corpuscle, placed near the head, and in which a very wonderful swift motion was to be seen, consisting of an alternate extension and contraction. Antonie van Leeuwenhoek
