The supposed conversion of base metals into gold or silver in alchemy.

The act of transmuting, or the state of being transmuted: change into another substance, form, or nature.

In geometry, the change or reduction of one figure or body into another of the same area or solidity but of a different form, as of a triangle into a square; transformation.

In biology, the change of one species into another by any means; transpeciation; transformism. The history of the idea or of the fact runs parallel with that of transformism, from an early crude or vulgar notion akin to that involved in the alchemy of metals (see above) to the modern scientific conception of transmutation as an evolutionary process, or the gradual modification of one species into another by descent with modification through many generations.

Successive change; alternation; interchange.
