If carmine has been mixed with the water, the atoms are seen in the customary vortex, and some are occasionally drawn into the cell nearly half-way down its cavity, and then swiftly driven out again. On a slight tap upon the table the animal withdraws, and in the same moment the urn bends down upon its leathery pedicle, at a point where there is always an angle, until the rim of the cell is in contact with the plant to which it is attached. This action is instantaneous. Presently, however, it rises, and resumes its former position, and then the mouth of the cell slowly opens, and the animal again protrudes, the cilia appearing first, and finally the head or front part of the animal, which is then opened and begins to rotate. Very similar to this are the Vaginicolm, but the cells which they inhabit are not stalked, but are immovably affixed to plants. In V. crystallina, the cell is a tall gob-.

Here is, fortunately, a group of the latter species, scattered about the leaves of the Nitella. Though, in general, both in form and habits, closely like the Cothurnia, yet the Vaginicola has some peculia-.
