SIR NORMAN LOCKYER AND OTHERS ON THE 
More refrangible than K .... 265 
K to Hy.190 
Hy to .178 
H/8 to D.223 
I'otal number . . . 856 
The intensities are on a scale such that 10 indicates the strons'est and 1 the 
faintest lines. 
The suggested origins have Ijeen tabulated in two columns, one in Avhich there is 
considerable certainty as to the origins suggested, and the other in which the evidence 
is not so complete. The general results with regard to the origins of the chromo¬ 
spheric lines are indicated hy the following table. 
Table showing the probable Presence or Absence of some of the Chemical Elements 
in the Chromosphere.
