THE LIVING STRUCTURES 133 



nest, which is lined by a capsule of hardened mucus 

 secreted by the glands of the skin. It hibernates thus 

 for nearly six months, drawing its sustenance from the 

 fat secreted when it is active." This fish is wonderful 

 in that it is able to make a nest in the mud, where it will 

 not lose any of its moisture, by lining its room with a 

 secretion which will prevent the escape of the moisture. 

 During its activity the cells in charge of this individual 

 gather and store away enough food in the way of fat so 

 they can live and enjoy life until the rainy season comes 

 again and provides the water to float them. The ability 

 of animals to store away food to be used at a future time 

 is a common habit, that is, with all animals that sleep in 

 the winter, like badgers, bears, etc. The cells in the body 

 gather and store food for the purpose of tiding over a 

 time when food will be scarce and hard to get. What 

 possible difference can there be in the intelligent purpose 

 evidenced by the cell in providing for the future, and the 

 animal and man doing the same thing? There can cer-. 

 tainly be none whatever. 



Take again for instance protective coloration. The 

 military experts are now adopting and taking advantage 

 of the tricks of the cell. The zebra in its bright stripes is 

 almost invisible in the jungles of his natural habitat. 

 When the cells building the zebra gave him the stripes 

 which make him so conspicuous in the circus they knew 

 what they were doing. The experience of hunters all 

 testify to the fact that the tall grasses and trees in the 

 jungle where he lives make the zebra almost invisible. 

 In reference to the cause of the color of animals, plants 

 and fish we have now fully demonstrated that it is caused 

 by the action of cells occupying the individuals, especially 

 if they have eyes with which to take a picture of the out- 

 side surroundings, and transfer this to the skin cells, who
