GLOSSARY. 415 



ZOOIDS. In many of the lower animals (such as the Corals, Medusae, &c.) 

 reproduction takes place in two ways, namely, by means of eggs and by a 

 process of budding with or without separation from the parent of the 

 product of the latter, which is often very different from that of the egg. 

 The individuality of the species is represented by the whole of the form 

 produced between two sexual reproductions ; and these forms, which are 

 apparently individual animals, have been called zooids.
