* In the solar spectrum these belong to a group of several lines. Of the 

 three most prominent, the middle line is Cr, with possibly a weak line on its 

 red edge ; and the red one is a close double, the violet component of the double 

 being Fe. (J.) 



t The solar line is a group of four lines. The third from the yiolet side is 

 the brightest and is Fe. 



$ Metal measured was Fe. § There is a faint line on the red side. 



|| Red component of double. 



Hf In the solar spectrum this is the red component of a double, the other 

 being cobalt. 



** The metallic line measured was Fe.
