40 Natural Salvation. 



higher degree of intelligence, from the exercise of which 

 each cell of the organic union was grandly benefited in 

 the matter of food and protection, and is enabled to 

 become a participator and beneficiary of mind. 



It may be added that the later physiology portrays the 

 connection and intercommunication of cells in metazoons 

 as based on and maintained by currents of "ions," 

 liberated and set in motion by the vital processes, and de- 

 picts life itself as arising from the reciprocal action of 

 these biogenetic units of matter. 



The passage from the unicellular to organized multi- 

 cellular forms of life, from protozoa to metazoa, was pri- 

 marily effected by simple combinations of cells and 

 varying of their functions. It was thus that the animal 

 organism originated. The question of importance next to 

 be asked is, What was gained by it ? Of what use was it ? 

 What advantage accrued from it to the cells themselves 

 which, from the strict biological point of view, are not 

 only the first, but the only type of life that has ever ap- 

 peared on the eai'th; since all life, organic as well as 

 unicellular, goes on by virtue and instrumentality of 

 the "cell" mode. 



What advantage therefore has accrued to the cell, and 

 how far has it by this means advanced toward that natural 

 salvation which is the goal of all life ? 



A survey of the whole field shows clearly that the 

 single cell made a great personal gain by uniting its life
