speak, comparable to Dz CanDoLLE’s system”. 
Thus having completed our circuit of Mt. Fuji, let us consider the 
beautiful vegetation of the mountain. However different be our starting 
point, after having completed ow: circuit and combined the different views, 
the correct idea thus acquired of the mountain is always the same. So it is 
with the natural system. No matter what system we take for a first con- 
sideration, after having considered all relations in all views, the result should 
be always the same. 
For the framework in constructing the dynamic system, I prefer 
Encer’s system to others, as it is the one most widely used by systematizers. 
For the present, I shall content myself with forming the system of the 
Angiosperms, as that class is the one with which I am most familiar, 
although I believe that systems for the other classes can be formed in the 
same manner. Now, to construct a dynamic system, arrange the series and 
families in the same order as in the system taken for a framework, and on 
both sides of a series or a family, put into such order as you like the several 
series or families respectively that are known to have some relations to the 
middle series or family, bearing in mind that the relative positions between 
the series or families thus arranged laterally and those in the middle vary 
with criteria. Next, put many short lines on both sides of the same series 
or families in the middle, a little more distant than the series or families 
already placed, keeping in view the fact that the lines denote series or families 
whose relations to the middle member are as yet unknown to us, though such 
surely exist, according to the participation theory. In the full extent of the 
latter theory, all the series and families, as many as are in the system, must 
necessarily be related in equal or different degree according as we consider 
the matter from the standpoint of universality or from that of particularity. 
The true method, therefore, in the above system - construction, is to arrange all 
series or families other than the middle one on both sides of the latter. 
1) For the sake of convenience, I have here metaphorically compared different systems to 
different views of the mountain. Yet, speaking more correctly, a static system such as 
Evycizr’s is something like a mosaic picture of the mountain, one part of which is taken 
from one view, and another part of which is taken from another ; while the real natural system 
is, as it were, comparable to the mountain itself.
