FRSTSCH, F. E., The use of anatomical characters for 



systematic purposes. (New Phytologist. Vol. II. No. 8. 



1903. p. 177—184.) 



This is a discussion of the systematic value of the different anato- 

 mical characters from the evolutionary point of view. The anatomical 

 strueture of any individual plant is due to two chief factors : we have to 

 distinguish those characters, which are derived from the ancestor, and 

 those, which have arisen by Variation and the influence of external con- 

 ditions. The former characters are those, to which most importance 

 should be attached, while the latter are at the most generally only of 

 specific value. The anatomical strueture of the different parts of the 

 plant is briefly discussed, most importance being attached to the stem.

Ganong, W. F., The Cardinal Principles of Ecology. 



(Science N. S. Vol. XIX. 1904. p. 493—498.) 



Enunciates and comments on five important principles which are 

 characterized as follows: 1. The reality of Adaptation; 2. the evolutio- 

 nary Phylogeny of Adaptation; 3. Adaptation a Race, not an Individual 

 Process; 4. Metamorphic Origin of Adaptation; 5. Inevitable Imperfection 

 of all Adaptation. H. M. Richards (New York).
