44 Natural Salvation. 



tection, and continued these unions till by division of 

 labor and differentiation of function the simple colony 

 developed into the vertebrate animal organism, with its 

 thirty specialized genera of cells, all acting together for 

 the common weal. 



Man must still turn to the unicells for grand examples 

 of social organization and progress by means of organiza- 

 tion. Vastly and grandly more than is yet exhibited in 

 human civilizations have the protozoons united and com- 

 bined for mutual betterment. In this maple, towering in 

 leafy beaut} r , we may find two billions of arboreal cells, 

 organized, apportioned for diverse labors, trained to 

 special work, devoted and artisaned to the production of 

 fiber, bark, sugar, and chlorophyl, and all in an orderly 

 sequence of effects and a consecration of each cell self to 

 its appointed task, and with an apparent content and faith 

 in the outcome, when each does his share, such as the 

 human world has never yet seen nor understood. 



In that horse dashing along the track we behold several 

 billions of cells, each a living creature, an individual life, 

 banded, united, and organized in such multicellular com- 

 plexity that it is the glory of anatomy and histology even 

 to have demonstrated and described it. And in the mat- 

 ter of locomotion since speed is the criterion in the 

 horse we may behold this entire body of cells moving 

 at a speed a million times greater than that at which it 

 would be possible for these cells to move if living isolated
