The Bell Animalcule (Vorticella) (fig 10) in certain respects resembles the Slipper Animalcule. It is generally attached by a slender stalk, and where many are growing together they appear like a delicate growth of mold upon the water weed. In figure 10 we see Vorticlla, an attached ciliate infusorian, highly magnified. (a) fully extented individual, (c.v.) pulsating vaculoe; (g) gullet; (n) nucleus. (b) contracted specimen, (c) small free-swimming individual, which unites with a statinary individual (one partly united is shown in specimen b).
