the will being under the influence of various kinds of compulsory 
choice in the lower, and intelligent option among higher animals. 
Thus intelligent choice may be regarded as the originator of the 
fittest, while natural selection is the tribunal to which all the re- 
sults of accelerated growth are submitted. This preserves or 
destroys them, and determines the new points of departure on 
which accelerated growth shall build. 
Acceleration under the influence of effort accounts for the exis- 
tence of rudimental characters. Many other characters will 
follow at a distance, the modifications proceeding in accordance 
with the laws here proposed, and retardation is accounted for by 
enon or absolute loss of growth force.
