If a single name is demanded for this conception of evolution it 

 might be termed the tetrakinetic theory in reference to the four sets of 

 internal and external energies which play upon and within every 

 individual and every race. In respect to form it is a tetraplastic 

 theory in the sense that every living plant and animal form is plas- 

 tically moulded by four sets of energies. The derivation of this 

 conception of life and of the possible causes of evolution from the laws 

 which have been developed out of the Newtonian system, and from 

 those of the other great Cambridge philosopher, Charles Darwin, 

 are clearly shown in the above diagram.
