In the first place I must refer to tables Iand II. Each column represents 
a frequency curve the apex of which is numbered in heavy type. In both 
tables I and II it happens that the different curves have their apices in a 
different situation. The curves do not correspond with each other. 
This comprehended as a transgression, it signified the first indication 
of the presence of more length and more breadth properties. 
The following curve (Curve I) is the fluctuation curve of the leaf- 
length of Coffea Robusta; and represents all the leaves from a single tree.

It is indeed noteworthy that some of the dimensions occur in such an 
increased number that a more-topped curve results, and that here it 
alone refers to a single specimen of C. Robusta. However it is still more 
important to be in the position to affirm, that this very same form of 
curve, thus consequently the same pronounced apices, were to be 
observed much earlier, even before all the material was utilized. The 
measurements began again at the foot of the tree, and were gradually 
extended to the top. During this time the tops on three different lengths 
of the tree, were united into one curve, as represented here by dotted 
lines. From this, one sees that even at such early stages precisely the 
same form of curve and precisely the same apices are to be remarked 
as in the definitive curve.
