cent more intense than that for neodymium chloride in pure alcohol. 

 On the ascending arms of the curves exactly the opposite effects are 

 noted. This indicates a displacement of the alcoholate band to the 

 region of longer wave-lengths. The displacement is very large in the 

 case of the first band. Neodymium chloride in 100 per cent water has 

 a band whose center is at X = 0.739^. When the solvent is 100 per
