covered with a pulp, and are swallowed by birds, but protected 

 by a hard covering from being digested, and so get distributed. 

 Some seed capsules at maturity suddenly burst open, turn 

 violently inside out, and scatter the seeds in every direction. 

 In the spore cases of the liverworts are two spiral fibres coiled 

 up like steel springs, and when the cases open they scatter the 

 germs. 



The protective power of the life intelligence or life instinct, 

 if you prefer the term is shown in flowers turning to the light ; 

 closing at night; closing to protect their pollen from rain. If 

 you say that cold or moisture produces these effects, you must 

 admit that certain flowers are made sensitive to cold and 

 moisture. We are sensitive to cold and shut the doors, put 

 on more clothing or build fires. The flowers fold up their 

 petals. 



Everywhere we see contrivance, design, adaptation of means 

 to ends, artistic taste, and mechanical skill, which can only be 

 attributed to a high intelligence joined to a power inconceiv- 

 able. To fancy that such things are the result of the play of 

 material forces, chemical affinities, and chance variations going 

 on through millions of ages, seems to me absurd. My mind, 

 by its very constitution, can conceive only of mind as the cause 

 of such operations.
