2io PICTURING MIRACLES 



leaving you still in doubt as to what it really is or 

 does. 



What it does or will show is still a matter of trying 

 it to find out, as almost nothing has been done in 

 picturing in natural color subjects so illuminated. 



In a few and simple words polarized light is, con- 

 sidering light as waves of energy, a light in which all 

 the horizontal waves have been eliminated and only 

 the vertical ones allowed to pass through, illumi- 

 nating the subject. A microscope designed for that 

 work costs about $1,000, or more with its attach- 

 mentsrather a large sum for anyone except the 

 most advanced worker and one able to have special 

 equipment for each type of work. One may buy from 

 Bausch and Lomb, Zeiss or Leitz, for much less than 

 $100, a Polarizer and an Analyzer, the former in- 

 serted in place of the condenser, and the Analyzer 

 above the eye piece, revolving the latter until the 

 nicols cross, giving the best illumination and the 

 darkest background. 



Certain subjects with this kind of illumination 

 show things in color not as visible as in ordinary 

 light. In plant and animal tissue it is much more 

 difficult to see, but in thin sections of some minerals 

 or crystals forming in a drop of water as it evap- 

 orates, the colors are so wonderful that any effort 

 would be worth while just to see them. To be able
