acteristics. Thus it may be hoped that these tables faithfully represent 
a permanent relationship between characteristics in individuals and 
between type and type. It is in this light that they should be read.

The Illustrations and the Tables. — If Figures 70 to 77 and 89, i.e. the 
photographs of the nine types grown as stools, are studied side by 
side with Table IV., section (i) General Habit, and the descriptions of 
the Pose in Relation to Stem in section (iv) Leaves, they will be 
found to show most strikingly the very obvious superficial differences 
of growth and leaf-pose. 
Figures 78 to 86 show the various summer details ; Table IV., 
section (iii) Lenticels, section (iv) Leaves, section (v) Leaf Stalk, and 
section (vi) Stipules are all well illustrated, the surface and pose of 
leaf being well brought out. 
* N.B. — Measurements were in all cases taken to the nearest millimetre and 
the averages were also calculated in the same way.
