All animals may be reduced to one or other of these classes. It 

 will be observed, that though the term ' Invertebrata' is introduced, 

 it is not employed as significant of any peculiar form. The reason 

 of this is, that it is merely a negative character, and such should 

 never be used where positive can be obtained. Its vagueness is 

 evident from its belonging to three out of four of the great primary 

 divisions of the 'Animal Kingdom.'
