the solution. Integration is also seen in the 

 rising of cream upon the surface of a dish of 

 milk, and in the frothy collection of carbonic 

 acid bubbles covering a newly filled glass of 

 ale. 



Obviously as it is through differentiation that 

 an aggregate increases in heterogeneity, so it is 

 through integration that an aggregate increases 

 in definiteness, of structure and function. But 

 there is still another way in which integration 

 is exemplified. Along with increasing hetero- 

 geneity and definiteness of structure and func- 

 tion, the evolution of an aggregate is marked 

 by the increasing subordination of the various 

 functions, with their structures, to the require- 

 ments of the general functional activity of the 

 aggregate. In other words, along with grow- 

 ing specialization of parts, there is a growing 

 cooperation of parts, and an ever - increasing 

 mutual dependence among parts. An illustra- 

 tion is furnished by the contrasted facts, that 

 a slightly evolved animal, like a common earth- 

 worm, may be cut in two without destroying 

 the life of either part ; while a highly evolved 

 animal, like a dog, is destroyed if a single artery 

 is severed, or if any one of the viscera is pre- 

 vented from discharging its peculiar functions. 

 This third kind of integration is the process 

 through which an evolving aggregate increases 

 in coherence. And with this, our definition of
