446 CLASSIFICATIONS OF ZOOPHYTES. 



divisions. Lamarck, although he also confined his examina- 

 tion to the polypidoms, took higher ground : he maintained 

 that as these were secreted by the polypes and formed on and 

 by them, a sameness in the structure of the one necessarily 

 implied a sameness in the structure of the other ; that in fact 

 we might as safely infer a sameness of structure or dissimi- 

 larity from the various configurations of the polype-cells and 

 coral, as we could from an actual inspection of the animated 

 tenants themselves. The experience of a few years has shown 

 either that Lamarck's examination of the coral was hasty, or 

 that his principle was erroneous, for his arrangement is far 

 from being in harmony with a physiological one, and, although 

 greatly superior to Lamouroux''s, yet is not the less artificial ; 

 there being even in some of his genera, species whose polypes 

 are widely at variance with each other. I do not mean to 

 trace the systems of either of these authors through their 

 various changes, from their first promulgation to their per- 

 fection;"'^ an outline of them in their latest state is sufficient 

 for our purpose.
