A substance of peculiar chemical and complicated molecular structure whose office is to perpetuate the species. At every ontogenesis a portion of the germ-plasma which the parent germ-cell contains is not used in the formation of the offspring, but is reserved unchanged to produce the germ-cells of the following generation. It is therefore as deathle as the species itself. The germ-plasma of each species is supposed to vary in complexity of chemical and molecular structure in direct proportion to the complexity of structure of the Individuals of the species.
