Translation of the original German introduction by Ernst Haeckel:
Phylum of Protista; - class of Infusoria; - subclass of Ciliata.
The body of Ciliata or Ciliata infusoria consists of one simple cell that is completely or partially covered with flexible ciliae. These Ciliae are used for locomotion (swimming and trailing) as well as groping and swirling in the later; with the help of this movement the cell body is supplied with nutrition and oxygen. Most Ciliata swim freely in water (fig. 1-6); others are temporarily attached (fig. 7, 8); some are permanently fixed (fig. 9-15). Among the latter many bud and thus form brachiate cell unions (Coenobia, fig. 11-15).
