Remarks. 
Lilies strouj' aud Avell dedued 
Lines all strong and well detiued. 
Continuous spectrum of carbonic 
oxide very strong, somewhat 
obscures the metallic lines 
3929-8 
3922 
3904-8 
3898-5 
Lines well defined 
The strongest lines in the spectrum 
dividing the visible 
ultra-violet rays 
from the 
Strongest part of the spectrum. 
Nearly all iron lines, many of 
which are very prominent. Con¬ 
tinuous spectrum not too strong 
to admit the lines being well seen
