The most refrangible constituent of 2878-52 widened into the 
» least refrangible one of 2878-03 and it was impossible to 
i isolate them. 
Widened into a band, and no clear and definite separation. 
\ The appearance of the triplet was not unlike that of 3128-82, i.e. 
L there were two sharp and strong constituents on the outside, 
I and an inside broad and weak one. 
) The least refrangible constituent coincided with the consti- 
j tuents of 2873-91 and it was impossible to separate them. 
Too weak to measure.
