Fernald has no entry of its own for metamorphose; he lists it under change.
Where he writes about it:
To metamorphose is to make some remarkable change, ordinarily in external qualities, but often in structure, use, or chemical constitution, as of a caterpillar into a butterfly, of the stamens of a plant into petals, or of the crystalline structure of rocks, hence called "metamorphic rocks," as when a limestone is metamorphosed into a marble. — from change
