   Two principles are postulated, according to which the elements have probably been evolved: (1) the ontogenic principle, involving the formation of the primary members of the different groups by direct condensation of protyl; (2) the phytogenetic principle, by which the higher members of the groups are developed from the lower by a process of integration.
