In the above tables the wave-lengths are those corresponding to Rowland’s second 
series of photographic maps of the solar spectrum. An origin stated without further 
comment signifies that there is a long line at that wave-length in the spectrum of the 
substance named ; but when a ? is added the coincident line of the substance is not 
one of the longest. Coincidencies with lines of cerium have not been considered.
