Turning his microscope in all directions, he examined water and found it peopled with minute animalcules, those simple forms of animal life propelled through the water by innumerable hair-like cilia extending from the body like. banks of oars from a galley, except that in many cases they extend from all surfaces. He saw not only the animalcules, but also the cilia that move their bodies. He also discovered the Rotifers, those favorites of the amateur microscopists, made so familiar to the general public in works like Gosse's Evenings at the Microscope. He observed that when water containing.
