and solitary, as did the ancestral protozoon on the beach 

 of the Cambrian Ocean. 



We should not here be understood as denying or leav- 

 ing out of the account the influence which the metazoic 

 mind exerts for longevity. It is by reason of this supe- 

 rior intelligence, obtained by banding the small wits of the 

 cells together, that those better conditions were gained 

 which make cell longevity possible. Nor yet would we 

 appear to assert that the animal organism lives for the 

 benefit, or at the behoof of the component cells. In the 

 animal brain the cells live to themselves only during the 

 eight or ten hours of sleep daily. During waking hours 

 the lives of all these cells are consentient, having banded 

 and blended together to form the self-conscious mind of 

 the animal, -which devotes its energies to supplying the 

 animal wants. Without this consentient union for men- 

 tation, locomotion, and general muscular activity, the 

 animal could not have developed. The component cells 

 improved, each its individual condition, by forming a con- 

 sentient paitnership. 



This point might readily be given fuller illustration, and 

 a thousand examples of metazoic life cited in evidence of 

 the principle, rationale, and intent of the passage from uni- 

 cellular to multicellular life ; but the idea has been con- 

 veyed ; and this is enough for our present purpose. The 

 genuineness of the deduction can hardly be controverted. 

 By banding together and by organization, with division of
