Angstrom represents this line as not absolutely 
coincident with a solar line which lies close to it. 
The Mn line is placed at about 4235-0, and the solar 
line 4234-7 ; the position given by Thalen is nearly 
the mean of these two. From its length we must 
conclude that it is reversed, and that the slight dis- 
crepancies between ThalLn in his metallic spectra
