the intensities of the lines as seen in the quantity coil with a 

 jar, and the solar lines 4918 being thinner than in the solar 

 spectrum. If we take the jar out of circuit 4923*2 almost dis- 

 appears, and we get nearly the same result as from the arc. 



We then try the intensity coil, which is supposed to give us 

 an equivalent of higher temperature than the quantity coil 

 does. What do we find then? That 4923*2 is enormously
