of the concentrated solutions of the chloride given in figs. 18 to 21. This 

 is what we should expect, since the concentrations of the nitrate solutions 

 are not so great. However, two of the absorption bands reach zero trans- 

 mission. A comparative study of any of these bands in the succeeding 

 curves shows that, just as was found with the chloride bands, they become

more intense with dilution. The decided decrease in the transmission in the 

 regions of the spectrum beyond 1/u is undoubtedly due to the increasing 

 absorption of water as the solution becomes more dilute. The other slight 

 deviations from Beer's law are not greater than could be accounted for by 

 the corrections mentioned under the discussion of the chloride curves.
