THE STORY OF ARTIFICIAL SILK 
University, New York City, made the startling 
discovery that Artificial Silk clothing admitted 
the Ultra-Violet rays. 
Cotton and woollen clothes are like armour- 
plate to these rays. They bar them from our 
bodies. Only our faces and hands are left 
open to the rays that are necessary to perfect 
health. When people wear broad-brimmed 
hats and gloves, they are shut out completely 
from these medicinal rays. Their bodies are 
wholly in the dark, so far as these rays are 
concerned. 
As we all know, the human race grew up 
in sunshine—sunshine that shone directly 
upon naked bodies. For hundreds of thou- 
sands of years the human race was a prac- 
tically naked race. It enjoyed 100 per cent. 
of the sun's rays. 
Clothes have only been worn in compara- 
tively recent centuries. First came the fig 
leaf or some other leaf, and then the skins of 
animals and then cotton and woollen clothes. 
Naked bodies were covered up. And what 
this has meant in weakness and disease we 
are only beginning to realize. 
After all, we have the same physical needs
