*Y. 3878.47 is not present unless it should be this line, which is scarcely 
credible. 3878.80 is certainly in satisfactory agreement with the iron line 
3878.78. But much stronger iron lines come out as impurities on the plates 
with much smaller intensities. The separation is unlike any other line of 
the triplet class in yttrium. The separation of Fe 3878.78 is unknown to 
the author, but should the separaticn of the Fe line prove to be some other 
magnitude, then the present line might safely be regarded an yttrium line, 
i. e. the magnetic separation may be used to determine the substance of 
doubtful lines. See also remarks upon Ba 6548.3, 6495.3, and 6484.7, table 
Baa.
