the essential processes of life, and hence what life 

 is. The study of the arrangements of organs is called 

 Morphology (the study of form) ; a new word, 

 which has to some extent superseded the older name 

 of Comparative Anatomy : its object is, to find out 

 how animals are related to one another by the com- 

 parison of their parts. Classification is Just a short 

 way of expressing the facts of Morphology : we put 

 all the animals that have their parts arranged in a 

 similar manner into one group, and give the group a 

 name. The study of the classification of the animal 

 kingdom is called Systematic Zoology.
