I do not know which are the new ones, but call attention to Silicon, 

 Vanadium, Scandium, Yttrium, Zirconium, Glucinum, Germanium and 

 Erbium, as being possibly new. 



Silicon has lines on my map at wave-lengths 3905-7, 4103-1, 5708-7, 

 5772-3 and 5948-7. That at 3905-7 is the largest and most certain. 

 That at 4103-1 is also claimed by Manganese.
