E signifies lines found in the photograjili of the corona spectrum taken in Egypt, 1882. 
In the column marked 1 the lines were found in three different measurements. 
In the column marked 2 the lines were found in two different measurements. 
In the adopted spectrum only those lines which were each measured by the two 
computers on each limb of the moon have been taken as coronal, unless a coincidence 
was noted between lines measured on one and the coronal spectrum of 1882 taken in 
Egypt. It will he noted that lines occurring in Ca and Fe lie very close to those 
given in the adopted spectrum.
