MORPHOLOGY, (Gr. μορφή, form), a term introduced by Goethe to denote in biology the study of the unity of type in organic form (for which the Linnaean term "Metamorphosis" had formerly been employed). It now usually covers the entire science of organic form. There are numerous restricted senses of the term in various sciences, but here we shall deal with it as a substantive side of zoology and botany.
