THE WONDERS OF LIFE 



ad Stage: Sensation op Molecules (groups of atoms) : in the 

 attraction and repulsion of molecules (positive and nega- 

 tive electricity, etc.). 

 3d Stage: Sensation op Plastidules (micella, biogens, or 

 plasma-molecules) : in the simplest vital process of the 

 monera (chromacea and bacteria). 



4th Stage: Sensation of Cells: irritability of the unicelliilar 

 protists (protophyta and protozoa) : erotic chemotropism 

 connected with the nucleus and trophic with the cell-body. 



Sth Stage: Sensation op Ccenobia (volvox, magosphsera) . 

 With the formation of cell-communities we have associa- 

 tion of sensations (individual feeUng on the part of the 

 social cells together with common feeling on the part of 

 the community). 



6th Stage: Sensation of the Lower Plants. In the meta- 

 phyta or tissue-plants all the cells are still equally sensitive 

 at the lower stages: there are no special sense-organs. 



7th Stage: Sensation op the Higher Plants. In the higher 

 metaphyta specially sensitive cells, or groups of cells, with 

 a specific energy, are developed at certain points: sense- 

 organs, 



Sth Stage: Sensation of the Lower Metazoa, without 

 differentiated nerves or sense-organs. Lower coelenteria: 

 sponges, polyps, platodaria. 



9th Stage: Sensation of the Higher Metazoa, with dif- 

 ferentiated nerves and sense-organs, but still without 

 consciousness(?). The higher coelenteria and most of the 

 coelomaria. 

 10th Stage: Sensation with Dawning Consciousness, with 

 independent formation of the phronema. The higher 

 articulata (spiders and insects) and vertebrates (amphibia, 

 lower reptiles, lower mammals), 

 nth Stage: Sensation with Consciousness and Thought: 

 amniotes: higher reptiles, birds, and mammals: savages. 

 12th Stage: Sensation with Productive Mental Action in 

 Art and Science: civilized men.
