556 SUMMARY AND CONCLUSION. 



distribution of Matter and Motion is usually accompanied 

 by secondary re-distributions. 



Distinguishing the different kinds of Evolution so pro- 

 duced as simple and compound, we went on to consider 

 under what conditions the secondary re-distributions which 

 make Evolution compound, take place. We found that a 

 concentrating aggregate which loses its contained motion 

 rapidly, or integrates quickly, exhibits only simple Evolu- 

 tion; but in proportion as its largeness, or the peculiar con- 

 stitution of its components, hinders the dissipation of its 

 motion, its parts, while undergoing that primary re-distribu- 

 tion which results in integration, undergo secondary re- 

 distributions producing more or less complexity. 



§ 187. From this conception of Evolution and Dissolu- 

 tion as together making up the entire process through which 

 things pass; and from this conception of Evolution as 

 dividing into simple and compound ; we went on to consider 

 the law of Evolution, as exhibited among all orders of 

 existences, in general and in detail. 



The integration of Matter and concomitant dissipation of 

 Motion, was traced not in each whole only, but in the parts 

 into which each whole divides. By the aggregate Solar 

 System, as well as by each planet and satellite, progressive 

 concentration has been, and is still being, exemplified. In 

 each organism that general incorporation of dispersed ma- 

 terials which causes growth, is accompanied by local in- 

 corporations, forming what we call organs. Every society 

 while it displays the aggregative process by its increasing 

 mass of population, displays it also by the rise of dense 

 masses in special parts of its area. And in all cases, along 

 with these direct integrations there go the indirect inte- 

 grations by which parts are made mutually dependent. 



From this primary re-distribution we were led on to 

 consider the secondary re-distributions, by inquiring how 

 there came to be a formation of parts during the formation
