| infusoria | <zoology> One of the classes of Protozoa, including a large number of species, all of minute size. They are found in all seas, lakes, ponds, and streams, as well as in infusions of organic matter exposed to the air. They are distinguished by having vibrating lashes or cilia, with which they obtain their food and swim about.They are devided into the orders Flagellata, Ciliata, and Tentaculifera. See these words in the Vocabulary. Formely the term Infusoria was applied to all microscopic organisms found in water, including many minute plants, belonging to the diatoms, as well as minute animals belonging to various classes, as the Rotifera, which are worms; and the Rhizopoda, which constitute a distinct class of Protozoa. Fossil Infusoria are mostly the siliceous shells of diatoms; sometimes they are siliceous skeletons of Radiolaria, or the calcareous shells of Foraminifera. Origin: NL.; so called because found in infusions which are left exposed to the air for a time. See Infuse. Source: Websters Dictionary (01 Mar 1998) |

It is used in polishing powder, and in the manufacture of dynamite. Source: Websters Dictionary (01 Mar 1998) |

| Infusoria |
A class of microscopic animalcules, so called from their having originally been observed in infusions of vegetable matters. They consist of a gelatinous material enclosed in a delicate membrane, the whole or part of which is furnished with short vibrating hairs (called cilia), by means of which the animalcules swim through the water or convey the minute particles of their food to the orifice of the mouth.
