of the individuals that represent the type at the
present moment, or in the growth of the germ of
every being born into that type to-day. In other

succession of geological ages controls the struct-
ural relations of all living beings as well as their
distribution over the surface of the earth, and is
repeated within the narrow compass of the small-
est egg in which any being begins its growth.
