ON THE CLASSES OF THE 



The foregoing observations I am well aware must be 

 far from accurate ; but they are sufficient to prove that 

 there are five great circular groups in the animal kingdom 

 which possess each a peculiar structure, and that these, 

 when connected by means of five smaller osculant groups, 

 compose the whole province of Zoology. As for the sub- 

 ordinate affinities, they had better be collected into one 

 tabular view, when it will be found that what, from my 

 imperfect description, may perhaps have appeared con- 

 fusion in the above detail, becomes order in the general 

 idea obtained of it from the following figure.
