Experemental Part: 



The iVleasurement of the Absorption Spectra. 



Tlu' al>-orptioii spectra of these salts were measured by means 

 of tlie quartz spectrograpJi of Adam Hilger & Co, London . 

 The concentrations of tlie solutions were viU'ied from ]/!()() X to 

 I/IOOO. Tiie salts used; were" specially purißed by recrystallization, 

 the formulae of some of^which were ascertained by analysis. \\'e 

 might go into discussions from tlie standpoint of the absorption 

 curves, which were dia^vn by the method suggested by Hartley 

 & Ealy. As the result, 'the eight compounds can be grouped 

 into two classes: to the first class'.belong
