The least refrangible constituent widened into 4549-90. 
' The line became a broad diffuse band, in which no separation 
could be seen. On analysis by the calcite it appeared to divide 
[ into three broad and diffuse constituents too weak to measure. 
The constituents widened and blurred into one another, and it 
was difficult to isolate those corresponding to the respective 
lines. 
I This line widened into a broad diffuse band like that of 4544-99. 
On analysis by the calcite it appeared to divide into three broad 
and diffuse constituents which were too weak to measure.
