' ' of Reflexion of Polarized Light, "^^ 



Table IV. 

 Azimuth of polarizer = 80°. Red sunlight. 



ms 



Here, as before, the fifth and sixth columns prove the truth 



of Laws I. and V., and a comparison of the column for j- with 



the' corresponding column of Table III. verifies, as far as it goes. 

 Law II. 



The principal incidence derived from the fifth column is 

 54° 27', at which incidence the quantity of light reflected in 

 the plane of incidence exceeds that in the perpendicular plane in 

 the ratio of 3'96 to unity. 



In the next table the azimuth of the polarizer approaches 

 nearer to the circular limit. 



Table V. 

 Azimuth of polarizer =85°. 



Red sunlight. 



This table verifies Laws I., V. and II. 



The principal incidence derived from the fifth column is 

 54° 59', and the quantity of light in the plane of incidence is 1*58
