PHYSIOLOGICAL ZOOLOGY 



CHAPTER FIRST. 



THE SPHERE AND FUNDAMENTAL PRINCIPLES OF 



ZOOLOGY. 



1. ZOOLOGY is that department of Natural History which 

 relates to Animals. 



2. The enumeration and naming of the animals which 

 are found on the globe, the description of their forms, and 

 the investigation of their 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 only when considered 

 as to the variety and elegance of their forms, or their 

 adaptation to the supply of our wants ; but the Animal 

 Kingdom, as a whole, has also a still higher signification. 

 It is the exhibition of the divine thought, as it is carried out 

 in one department of that grand whole which we call Na- 

 ture ; and considered as such, it teaches us the most im- 

 portant lessons. 



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

 and the material, is qualified to comprehend Nature.
