SPECTRA OP SOME OF THE BRIGHTER STARS. 
689 
(1.) Table A.—Stars in which there is no remarkable continuous absorption either in 
the ultra-violet or violet. In these stars the hydrogen lines are broad. 
(«•) 
The spectra differ widely 
from the solar spectrum. 
There is only a small 
number of lines, and the 
hydrogen lines are not 
of extreme thickness. 
(/^.) 
The spectra do not differ 
very widely from the 
solar spectrum, There 
•is a large number of 
lines, but the hydrogen 
lines are not of extreme 
thickness, though much 
thicker than in the 
solar spectrum. 
(7-) 
The spectra show very 
broad hydrogen lines, 
and, in addition, faint 
representatives of some 
of the lines seen in stars 
of sub-division a.

lines seen in stars of

Many of the photographs are on too small a scale or are too ill-delined to show more 
than that there is no remarkable absorption in the violet or ultra-violet, and that the 
hydrogen lines are broad. These are as follows :—
