THE beech tree (fagus sylvatica), from which the leaves ex- 

 amined were gathered, stands in the Botanical Garden of 

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

 of four different sizes, on May 16, 1861. 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 5 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. 



The leaves of the IV. period were from the same tree, but had 

 been gathered in the end of November, 1860. They had withered 

 on the tree, and were quite dry.
