Paleontology. The study of fossil animals (paleo- 

 zoology) is a division of morphology since the in- 

 vestigation of the physiology of fossil remains is not 

 practicable. That part of it that deals with animal 

 forms is zoological rather than geological. It is a 

 study of the succession of animal life on the globe. 

 In passing, it should be remarked that the succes5ion 

 of plant life (paleobotany) has been in recent years 

 the field of very notable advances. 



Systematic Zoology. Deriving its name from the 

 systematic arrangement of animals as first accom- 

 plished in the Systema Naturae of Linnaeus. Since 

 classification is based largely on structural features, it 

 would appear that in its recent scientific aspects, it 

 should be the outcome of morphological study and 

 such is the case. But this was not so in earlier 

 times Systematic Zoology had large development 

 before morphology pushed into prominence. It 

 arose out of the old natural history of Linnaeus. The 

 designation natural history is, however, more com- 

 prehensive than classification. It represents the 

 kind of study of animals to which the name zoology 

 was applied after the Renaissance. After the rise of 

 morphology, natural history continued to develop 

 and took on modern form. To this division belongs
