Theoretically spaaking, jxll the members (series as well as ftimilies) in the 

 dynamic system should be mentioned repeatedly i. e. as many times as the 

 nnmber of series or famiUes respectively. But, for practical pui-poses, the 

 system may, as mentioned above, be simphfied by arranging only those series 

 or famihes whose relations to the middle members are so far known t<3 us, 

 and by adding thereto a few short Hnes symboHzing or representiug as many 

 series or families, other than those laterally an-anged and the middle member. 

 To make what we present to onr readers as a dynamic system as compre- 

 hensible as possible, it may conveniently be formed of fovu* parts, namely : — 

 the participation theory upon which the system is grounded, the system itself, 

 the explanation of the latter, and finally the index to the members of the 

 system. Now, on the side of the reader, iu order to understand thorouglily 

 the dynamic system thus presented, they should, first of all, master the 

 participation theory, then proceed to study the system itself, then look at the 

 explanation of the latter, and finally go to the index, espacially when they 

 have sometliing in mind, the natural position of which they wish to fiud in 

 the system. These four parts are, however, iu final analysis resolvable to 

 oneness, — each being in itself the theory, each in itself the system, and so 

 on. I have described the participation theory above ; so I shall uow give 

 the system and then the explanation and the index, in the following pages.
