32 ABSORPTION SPECTRA OF AQUEOUS SOLUTIONS OF CERTAIN SALTS 



tion. By repeating this procedure any wave-length could be allowed to fall 

 on the junction. If we represent by I the deflection with the solution in the 

 path of the beam of light, and by Jo the deflection with the solvent in the path 

 of the light beam, the percentage of light which passed through the solution 

 would be represented by I/Iq. In tables 2 to 5 we have the ratio of I/h.
