8 THEORY OF ORGANIC EVOLUTION. 



into idioplasm, in which at certain favorable points 

 the micellae that are being stored up under the influ- 

 ence of molecular forces arrange themselves into 

 groups by similar orientations, and hence form 

 bodies of less water content and greater solidity. 

 Each body of idioplasm consists originally of only 

 one group of micellae, which, however, necessarily 

 breaks up with increasing additions into several 

 groups. On account of the dynamic influence of the 

 groups of micellae upon their own growth, they 

 become in part more distinct and more definitely 

 separated, in part again differentiated by new 

 irregular intussusception. This phylogenetic proc- 

 ess is continued indefinitely, by which the com- 

 bination of forces produces a new configuration, and 

 conversely, by which a new configuration produces 

 a new combination of forces, so that the body of 

 idioplasm merely takes on a continually increasing 

 complexity of configuration by the action of the 

 internal forces that is, by the molecular forces of 

 the micellae of the albumen under the influence of 

 which growth proceeds. This constitutes the auto- 

 matic perfecting process or progression of the idio- 

 plasm, and entropy of organic matter. (See p. 47.) 

 The above described phylogenetic perfecting 

 process of the idoplasm, which operates through 

 internal causes, is scarcely affected by differences of 

 nutrition and by climatic conditions influencing 

 nutrition. On the other hand all those external
