In the Star-fish, a considerable power of regenerating lost parts has been observed ; but this appears to be confined to the reproduction of the arms from the body. As it does not seem that the body can be regenerated from the arms, or from a half of itself, no multiplication of individuals can take place in this manner; and in this class there is no propagation by buds, as in the group just mentioned. In Animalcules, however, we find this process, or a modification of it, to be almost the only means of re- production, which the beings composing that wonderful group pos- sess ; for the greater number of species never deposit eggs, but multiply themselves by the development of buds, or by the division of their own bodies. The former process may be continually wit- nessed by the microscopic observer, in the common Vorticella, a.
