different solvents as entirely different bands.) As a consequence, the 

 more concentrated solutions appeared a deep purple, becoming more 

 and more pink as the dilution increased. 



The A c curve for 744/iju shows that A decreases by a large amount 

 with dilution, dropping from 0.128 for c = 0.7 to 0.080 for c = 0.1. 

 This is the only Ac curve which has been plotted for a wave-length
