220 THE CHEMISTRY OF THE SUN. [CHAP. 



Vanadium. Reversal of 4 lines at wave-length 4379 '0, 4384-0, 

 4389-0, and 4407 -5. 



Palladium. Reversal of 5 lines at w.l. 3893-0, 3958'0, 4787*0, 

 4817-0, and 4874-0. 



Molybdenum. "Reversal of 4 lines at w.l. 3902-0, 4576-0, 4706'0, 

 and 4730-0. 



In many cases the result was still left doubtful. 



Indium. One line at wave-length 4101 was coincident with H, a 

 hydrogen line.^ The reversal of another line at w.l. 4509 '0 was 

 doubtful. 



Lithium. One line at w.l. 4603-0 was reversed, but the reversal 

 of the long red line at w.l. 6705 was not detected. 



Rubidium. One long line at w.l. 4202'0 was reversed, but solar 

 lines corresponding to the long red lines at w.l. 6205 and 6296 

 were not traced. 



Ccesium. Two lines at w.l. 4554'9 and 4592 were possibly 

 reversed. 



Bismuth. One line at w.l. 4722*0 was reversed, but further 

 evidence was considered necessary. 



Tin. One line at w.l. 4524 was apparently reversed, but further 

 evidence was desirable. 



Glucinum. One line at w.l. 3904*77 was apparently reversed, 

 further evidence desirable. 



Lanthanum. Three winged lines at w.l. 3948 '20, 3988 '0, and 

 3995*04 were reversed. 



Yttrium, or Erbium. Two lines at w.l. 3981-87 and 3949'55 

 were reversed. 



The upshot of this work, then, comparing it with what Had 

 gone before, .gave us the following metals existing, with more or 

 less probability, in the atmosphere of the sun : 



Hydrogen, sodium, calcium, magnesium, iron, manganese, 

 titanium, chromium, nickel, barium, zinc, cobalt, aluminium, 

 strontium, lead, cadmium, cerium, uranium, potassium, vana- 

 dium, palladium, molybdenum, indium, lithium, rubidium, 

 caesium, bismuth, tin, glucinum, lanthanum, yttrium or erbium.
