ANALYTICAL TABLE or CONTENTS. 



BOOK I. The work commences with a general review of 

 the animal kingdom, and several suggestions for a natural 

 arrangement of animals in groups, according to their 

 external form or their mode of life, a comparison of animals 

 among themselves, and a description of some of their habits.
