The author admits of three primary groups of animals : — 

 The Binary of M. de Blainville, the Radiate, and the Homo- 

 geneous. These groups represent three terms of a very regular 

 series ; and their essential characters admit of being brought under 

 geometrical and arithmetical considerations. 



From the first to the last, similarity is manifested more and more 

 strongly, whilst the mode of co-ordination becomes simplified. Thus 

 in the first group, to take the geometrical character, the co-ordina- 

 tion of the similar parts takes place in relation to a plane, or more 

 generally to a surface ; in the second, in relation to a line ; and in 

 the third, to a point, spine, axis, or centre. In the first division, 

 moreover, the corresponding parts are repeated in pairs; in the second, 

 in groups of several to several ; and in the third, in a very great or
