afford support.

FERTILIZATION IN PLANTS 
The exhibit demonstrates the peculiar nature of the process of fertiliza¬ 
tion,- and the special mechanisms that these organisms have developed to 
bring about fertilization in various ways. The processes are adjusted 
intimately to the visits made by insects to flowers for nourishment.

THE DESCENT OF MAN 
The general principles of evolution hold true for the attainment by the 
human species of its present place in nature. The exhibits demonstrate in 
a general manner the various stages reached by organisms nearly related to 
man, which the human species has surpassed. 
Illustrations

2. A series of crania of primate mammals, showing the gradual 
enlargement of the brain case and the relative reduction of the 
jaws. 
3. A series of casts and models of the brains of various primates, 
showing the progressive evolution of the brain, and especially 
of the cerebrum.
