The three constituents appeared to be equally strong. 
Too weak and diffuse. 
The three constituents were equally strong. 
Too weak and diffuse. 
The three constituents were equally strong. 
Exner and Haschek give one line at 3349-16, whilst Eowlaud 
gives three at 3349 '043, 3349-135 and 3349-212. There are 
three lines well seen ; a strong one at 3349-16 and two weaker 
ones, one on each side of this. The three constituents of 
3349-16 are equally intense, and the least refrangible one 
widens into those of 3349-70. Also 3349‘7 is reversed nor- 
mally, whilst 3349-16 is not. 
The three constituents were equally strong. 
Too weak and too diffuse. 
The constituents were very diffuse.
