SIR NORMAN LOCKYER AND MR. F. E. BAXANDALL 
(arc lines prominent, enhanced lines weak or absent) and those of a Cygni (enhanced 
lines prominent, arc lines weak or absent), 
3. The enhanced lines of scandium, strontium, and titanium are better develoj)ed 
than in a Cygni, l^ut those of iron, chromium, and magnesium are less conspicuous 
than in a Cygni. 
4. The relative intensities of the metallic and proto-metallic lines are about the 
same as in the spectrum of the solar chromosphere, which, if anything, represents a 
slightly higher temperature. 
Wave-lengths, Intensities, and Probable Origins of y Cygni Lines, compared with 
those of S Canis Majoris, the Chromosphere, and a Cygni.
