The reason for plotting this quantity is that it is the most 

 convenient for comparison with experiments. Measurements 

 on the polarization of light scattered from a turbid medium 

 are best made with a Cornu polarimeter, consisting of a 

 small rectangular opening through which the light to be 

 examined passes, a double-image prism, and a nicol capable 

 of being rotated about its own axis and attached to a divided 

 circle. The double- image prism is fixed at such a distance 

 from the rectangular opening that the two images, one 

 polarized vertically and the other horizontally, are seen side 

 by side. These are viewed through the nicol, which is then 

 set so that the two images appear equally bright. If the 

 zero position of the nicol is taken to be that position in which 

 it transmits only the vertical component, and the angle
