152 life's beginning on the earth 



SUMMARY 



Salt and water are a part of life itself. We see their 

 expanding forces in simple artificial cells made of gelatin, 

 in real living cells, and particularly in the artificial osmotic 

 structures which are inorganic and yet counterfeit life 

 amazingly well. We see why and how our own blood has 

 been developed in early evolution from the ocean, which is 

 the cradle of life. New facts thus elucidate the nature of 

 growth, but mainly growth in the plant kingdom. In the 

 fourth and last act, now to follow, observations will be 

 presented through which we shall try to understand the 

 mechanism of motion in the animal world.
