been known to the cell for ages. Man with the phenom- 

 enon before his eyes on sea and land, spending fortunes, 

 investigating this and trying to discover the secret, is 

 not yet able to produce it. A text book on physics has 

 the following to say about it : 



"We burn a jet of gas in order to produce artificial 

 light. We are seeking to set up ether waves of a certain 

 length but in doing so we produce only three per cent of 

 these waves and 97% of waves we do not wish and could 

 do very well without, as they are simply dark heat waves. 

 The hotter the body is which is setting up the ether 

 waves, the better is the percentage of useful waves, but 

 even with electric arc lamps we can only attain an effi- 

 ciency of ten or fifteen per cent. If we could only imi- 

 tate nature as we see her producing light in the glow 

 worm, where practically the whole of the ether disturb- 

 ance is in the form of visible light no dark heat waves 

 being produced we should be able to cause illumina- 

 tion on a grand scale. Referring to the luminosity of the 

 glow worm, Sir Oliver Lodge has remarked that if we 

 could only obtain this secret from nature, a boy turning 

 a crank could furnish sufficient energy to light an entire 

 electric circuit." 



You will notice how they put it. They say if we 

 could "imitate nature" or "discover the secrets of na- 

 ture." Why not tell the truth and say the secrets of the 

 cell? What is the reason for all this meaningless lan- 

 guage and jumbling of words? Whether you say the 

 secrets of nature, the secrets of the universe, the secrets 

 of the world or the secrets of the moon, we understand 

 one about as well as the other. If the cell living a single 

 life in the open, or in a colony like the glow worm or 

 lightning bug, can produce this light, why not be honest 

 about it and admit the truth? There can be no question
