PHYSIOLOGICAL ZOOLOGY. 



CHAPTER FIRST. 



THE SPHERE AND FUNDAMENTAL PRINCIPLES OF 



ZOOLOGY. 



1. ZOOLOGY is that department of Natural History which 

 relates to animals. 



2. To enumerate and name the animals which are found 

 on the globe, to describe their forms, and investigate then- 

 habits and modes of life, are the principal, but by no means 

 the only objects of this science. Animals are worthy of our 

 regard, not merely when considered as to the variety and ele- 

 gance of their forms, or their adaptation to the supply of our 

 wants ; but the Animal Kingdom, as a whole, has a still 

 higher signification. It is the exhibition of the divine thought, 

 as carried out in one department of that grand whole which 

 we call Nature ; and considered as such, it teaches us most 

 important lessons. 



3. Man, in virtue of his twofold constitution, the spiritual 

 and the material, is qualified to comprehend Nature.
