238 CELL, INTELLIGENCE THE CAUSE OF EVOLUTION 



is considered to be the vibration of ether. When the 

 ether vibrations traverse any material, they produce two 

 different results : First, they raise the temperature ; sec- 

 ond, they occasion chemical energy. The first is called 

 absorption of light, the second chemical change. Gases, 

 liquids and solids all respond to ether vibrations, such as 

 the explosive mixture of hydrogen and chlorine, chlorine 

 water, which gives up oxygen, and phosphorous which 

 changes to red, or cinabar which turns to black. Now, 

 what is the cause of these light vibrations? 



"The latest authorities maintain that light vibrations 

 are produced by electric agitations, and that in the chem- 

 ical action of light we deal with phenomena not far re- 

 moved from the formation and decomposition of com- 

 pounds under the influence of the galvanic current. 



"The action of light waves (according to latest theo- 

 ries) are the rapidly alternating electric fields. From these 

 conclusions we may assume that the ultimate cause of the 

 photo-chemical action of light lies in electric phenomena." 



The most common and abundant single cell that we 

 have in our ponds and lakes which makes its own starch 

 or food, is the cell called euglena. This is what you 

 might call a minute invisible green plant. These Euglenas 

 are again eaten by other cells that do not understand how 

 to make starch for food. The Euglena is known as the 

 green scum of sewers, lakes, ponds, streams and muddy 

 places. As soon as it finds itself in darkness or light too 

 weak to aid it in its starch-making activities it moves into 

 a better light. Euglenas are cigar shaped with a tail for 

 a propeller, which works like a cork screw. The starch 

 factory is carried at the front end. Under the microscope 

 these creatures can be seen gathering together at certain 

 places where the light is not too weak nor too strong, 

 generally about two or three inches under the water.
