The formation and storing of perpetuation areas represents no 

 break or radical difference in the general habit of the mass 

 substance. It is to be remembered that food secured by the 

 organism is always for activities of the future, for even remote 

 contingencies as well as for immediate or certain rhythmic 

 needs. That some of these needs will not arise till a portion 

 of the existing mass shall be leading an independent existence 

 matters little, for the sequence of structures and especially of 

 function has still for this a certain and a true continuity. 

 Considerable interval must always elapse after taking food 

 before the general and local substance has use of it. A stor- 

 ing of perpetuation areas with specific environmental condi- 

 tions needed for its sequent phases and phenomena is, 

 therefore, one with all the phenomena of distribution of 

 materials throughout the mass, one with all preparation made 

 by a larval stage for other larval, or for adult stages. And 

 indeed the "adult" stage in many cases becomes absolutely 

 parasitic upon the "larval" stage. In such cases it is the 

 whole and not merely a portion of the mass that becomes 

 fosterling, for which the precedent phase acts as foster parent. 

 Some adult phases are as absolutely dependent on this as the 

 ovum is upon the mother organism. In pupa states again, the 

 whole organism passes through an egg-like phase, becoming 

 regenerate and transformed. The male rotifer must again be 

 cited in this connection as an illuminating form. By regard- 

 ing the organism as a recurrent grouping of substance organs 

 and substance functionings, — as a rhythmic set of substance 

 habits, — the whole living universe comes more within one's 

 comprehension, because expressed in more unifying terms. 



But it is manifest that while the creature we know, is built 

 up of substance organs, it can hardly be taken to be by itself 

 the whole meaning, a mere summation of those found in it. 

 In each organism there are probably vast numbers of true 

 substance organs existing and functioning with little or no 

 reference to it, except as they are indirectly dependent upon 

 it as general purveyor. Each of these may represent some 

 attained end or cast-off function which will disappear — van- 

 ishing characters in process of elimination from the race
