It is therefore through this fact that I have concluded to designate 
this definitive curve as a more-topped one. 
What we perceive here in the curve of this single tree, especially in 
the length of its leaves, is the same phenomenon which is indicated in 
the “populations” with a transgression of properties, and in these cases 
considered as an indication for more “small species”. I am inclined to 
apply the same interpretation in my case, and thus to see in it that where 
the curve represents the fluctuation of leaf-length it is also an indication 
that we have to deal here with more length-properties in this single 
Robusta tree. What here applies to length, serves also for breadth. In the 
Curve IE 
latter case, however, the apical plurality is not so apparent when one con- 
siders that the width of variation is much smaller; and that consequently 
the tips lie so close to each other that they scarcely seem isolated. We 
will now resort to another method, by which the presence of more breadth- 
qualities can be revealed with clear conviction. In the further demonstration 
of this, I make use of it at the same time to show, how, with the definitive 
end curve alone applied, the presence of more tops and so of more pro- 
perties is not to be understood. 
As a pendant of the Rodusta curve (in curve I) there is shown below 
a fluctuation curve of the leaf-length of C. Uganda (curve II). In this 
curve is assimilated the end curve of the length of all the leaves on that tree. 
As one perceives, this is a single topped curve, just as we should have 
surmised, and nothing appears to indicate that this matter is in reality
