THE beech tree {fagus sylvatica), from which the leaves 

 examined were gathered, stands in the Botanical Garden of 

 Munich. The leaves marked I. period were taken from the tree 

 of fom- different sizes, on May IG, 1801. The smallest leaves a 

 were just unfolded from the leaf-bud, whilst those marked d 

 were fully expanded. There were between a and d a difference 

 of four days' growth. The other two sets, marked severally b 

 and c, were in size and period of growth intermediate between 

 a and d. The leaves of the I. period were very delicate, and of 

 yellowish green colour. 



The leaves of the II. period were gathered on July 18, those 

 of the III. period on October 15, 1861. The leaves of each 

 period possessed among themselves the same size and firmness 

 of structure. The colour of the July leaves was dark green, of 

 those of October somewhat lighter.
